Effects of silane treatment on the bond between steel fibres and mortar
Publisher: Thomas Telford Ltd.
Date: 05-2022
Abstract: The ability of fibres to resist crack growth in fibre-reinforced concrete can be significantly influenced by the fibre–matrix bond. This investigation reveals surface treatment of fibres as a viable technique for developing a uniform bond along the fibre–cement interface to resist growth of microcracks and thereby complement the physical restraint against pull-out provided by fibres’ shape and friction. Previous reports have shown effective chemical treatment of glass, carbon and polypropylene fibres. However, research into chemical surface treatment processes for steel fibres, the most common in concrete, is scarce and focused on corrosion and dispersion, rather than the fibre–matrix bond. Here, a silane treatment technique is proposed to strengthen the steel fibre–cementitious matrix bond. Surface energy measurements and X-ray photoelectron spectroscopy demonstrate the effectiveness of this treatment. Fibre pull-out tests conducted on silane-treated fibres show an apparent increase in pull-out energy, accompanied by a delay in reaching the peak load, compared with untreated fibres, suggesting increased resistance to crack initiation and growth. Furthermore, the results indicate improved flexural strength and direct tensile strength of mortar reinforced with silane-treated fibres compared with untreated fibres. The improvements are further corroborated by results from restrained drying shrinkage and volume of permeable voids.

The behaviour of steel-fibre-reinforced geopolymer concrete beams in shear
Publisher: Thomas Telford Ltd.
Date: 03-2013
Abstract: An investigation of the shear behaviour of steel-fibre-reinforced geopolymer concrete beams is presented. Shear tests were conducted on five series of 250 mm deep by 120 mm wide beams spanning 2250 mm. The beams did not contain conventional web reinforcement (stirrups), but were reinforced with end-hooked and straight steel fibres in various fibre volumetric dosages, ranging from 0 to 1·5%. The test results show that the shear strength increases significantly as the fibre content increases and that improvement in the cracking behaviour is achieved through the addition of fibres. The results of the test were compared with the fib Model Code 2010 alternative model for shear strength of steel-fibre-reinforced concrete in combination with the variable engagement model for the determination of the tensile strength of steel-fibre-reinforced concrete. A good correlation is observed for the predictive model with the test data.

Creep and drying shrinkage of a blended slag and low calcium fly ash geopolymer Concrete

DOI: 10.1617/S11527-015-0599-1
Abstract: The main purpose of this research is to study the time dependent behaviour of a geopolymer concrete. The geopolymer binder is composed of 85.2 % of low calcium fly ash and only 14.8 % of ground granulated blast furnace slag. Both drying shrinkage and creep are studied. In addition, different curing conditions at elevated temperature were used. All experimental results were compared to predictions made using the Eurocode 2. The curing regime plays an important role in the magnitude and development of both creep and drying shrinkage of class F fly ash based geopolymer concrete. A minimum of 3 days at 40 °C or 1 day at 80 °C is required to obtain final drying shrinkage strains similar to or less than those adopted by Eurocode 2 for ordinary Portland cement (OPC) concrete. Creep strains were similar or less than those predicted by Eurocode 2 for OPC concrete when the geopolymer concrete was cured for 3 days at 40 °C. After 7 days at 80 °C, creep strains became negligible.

Behaviour of precast concrete deck slabs with transverse confining systems
Publisher: Thomas Telford Ltd.
Date: 09-2016
Abstract: The enhanced loading capacity of transversely confined concrete deck slabs has been demonstrated through different studies, but the available transverse confining systems used in conjunction with cast in situ concrete deck slabs are not conducive to deconstruction. This paper presents the results of an experimental study on precast slabs attached to girders using bolted shear connectors. Ten half-scale precast slabs are tested under a monotonically increasing force applied at the mid-span. The configuration and proportion of the reinforcing steel bars and types of transverse confining system (cross-bracings or ties) are the main test variables. The experimental results demonstrate the efficiency of the proposed system for mobilising arching action in the precast concrete deck slabs. Also, it is shown that the location of reinforcing bars in single-span concrete slabs with transverse confinement can significantly influence the load capacity and ductility, but the top reinforcing steel bars have negligible influence on the peak load and ductility. In addition, detailed finite-element models of the specimens are developed and verified against test results and it is shown that the adopted finite-element models can adequately capture the local and global response of the transversely confined deconstructable precast concrete deck slabs.

A Smeared — Fixed Crack Model for FE Analysis of RC Membranes Incorporating Aggregate Interlock

DOI: 10.1260/136943306776232927
Abstract: This paper reports the development of the cracked membrane model using a fixed-crack approach for the finite element modelling of orthogonally reinforced structural elements under plane stress. The model falls into the broad category of “compression field models” combining elemental components from the modified compression field theory with those of the tension chord model. The tension stiffening effect is developed using a steel-concrete bond relationship with its basis in limit analysis. With this approach the tension stiffening and tension softening components of the concrete tension resistance mechanism are decoupled allowing for rational models for each component. With adoption of a fixed crack formulation aggregate interlock along the cracks is explicitly modelled allowing for modelling of reinforced concrete members containing no or low quantities of steel reinforcement where slip along cracks significantly affects the results. For ex le, the modelling of shear critical beams containing low shear reinforcement volumes. The model has been incorporated into the finite element program for the analysis of reinforced concrete structures with verification of the finite element model presented.

Precision of cement hydration heat models in capturing the effects of SCMs and retarders
Publisher: Thomas Telford Ltd.
Date: 12-2018
Abstract: A major input to numerical simulation models used to predict the risk of early-age thermal cracking in concrete is the hydration heat estimation. The precision of hydration heat estimation models has been extensively verified for different cement compositions in previous studies. However, little has been done to investigate the accuracy of such models for concrete mixes containing supplementary cementitious materials and retarders. This paper presents the results of a series of isothermal calorimetry tests conducted first to investigate the effects of Class F fly ash, ground-granulated blast-furnace slag (GGBFS) and three commonly used retarders (namely, retarder N, sucrose and citrate) on the heat of hydration profile of Australian general-purpose cement under different curing temperatures of 10, 23 and 30°C, and second to evaluate the precision of the two most commonly used hydration heat models in capturing the effects of fly ash, GGBFS, retarders and curing temperature on the hydration profile. The results reveal the possibility of considerable errors in estimating the hydration heat of concrete mixes containing supplementary cementitious materials and retarders under different curing temperatures, highlighting the need for re-calibration of the existing models for locally used materials to avoid misleading errors in numerical simulation of early-age thermal cracking.

Modelling the tension stiffening effect in SFR-RC
Publisher: Thomas Telford Ltd.
Date: 04-2016
Abstract: The understanding of the performance and cracking behaviour of steel fibre reinforced concrete (SFRC) has developed greatly in recent times. Many of these studies, however, are limited to SFRC without conventional reinforcement. This paper reports on the tensile behaviour of SFRC members co-reinforced with conventional reinforcing bars (SFR-RC). A physical description of the behaviour of the specimens is presented and an analytical model is derived. The model adopts the load-sharing concept between the tensile stresses resisted by the steel fibres and the steel reinforcing bar as well as the bond between the concrete and reinforcing bar to the tension stiffening effect of these members. The model is founded upon a previously reported tension chord model and allows for explicit identification of the three components to the tension stiffening effect. An experimental programme is reported here and the model is shown to correlate well with the experimental data and test data reported elsewhere.

DOI: 10.1260/1369-4332.16.12.1989
Abstract: An efficient frame finite element (FE) is developed and applied for nonlinear analysis of reinforced concrete beams flexurally strengthened with externally bonded fibre reinforced polymer (FRP) strips lates. The developed nonlinear model is able to capture different failure modes associated with concrete crushing and cracking, yielding of steel, FRP rupture and intermediate crack-induced debonding of FRP sheets lates. The element is formulated using force interpolation concept and a simple approach based on application of discrete springs and linear interpolation of bond forces along the element axis is adopted to take account of shear-slip. The developed formulation and analytical tool are employed to predict the loading capacity and the load-deflection response of reinforced concrete beams strengthened with FRP and the numerically simulated responses agree well with the corresponding experimental results. The major features of this frame element are its simplicity and efficiency compared with more complex FEs which makes it a suitable tool for practical use in design-oriented parametric studies.

Behavior of Postcracked steel fiber‐reinforced concrete in fatigue and development of a damage prediction model
Publisher: Wiley
Date: 09-05-2022
Abstract: This paper reports the results of 27 tests on determinant round panels undertaken to determine the postcracking resistance to repeated cycling (fatigue) loading of steel fiber reinforced concrete (SFRC) of low fiber dosages. The experiments were conducted for both precracked and uncracked panels to examine the contribution of postcracking tensile strength, and the effectiveness of steel fibers in providing resistance to fatigue damage. The results quantify the improvements of fibers to fatigue life of SFRC and, particularly, to the important second stage of crack growth during cyclic loading. From the outcomes of the testing program, a damage prediction model is proposed for forecasting postcracking fatigue damage during repeated cyclic loading. The model is shown to accurately predict the overall load‐stiffness response, capture the development crack openings with increasing cycles, as well as quantify the stiffness development and number of load cycles to failure.

Abstract: The ability of the short, proline-rich native antibacterial peptides to penetrate bacterial and host cells suggests the utility of these transport systems in delivering peptidic cargo into cells. We studied the uptake of pyrrhocoricin and its most potent dimeric analogue by bacteria as well as human dendritic cells and fibroblasts. Native pyrrhocoricin entered the susceptible organism Escherichia coli very efficiently and the nonsusceptible bacterium Staphylococcus aureus to a significant degree. The antibacterial peptide also penetrated human monocyte-derived dendritic cells. It failed, however, to enter fibroblasts, whereas the designer analogue Pip-pyrr-MeArg dimer penetrated all the cell types that were studied. When glucoincretin hormone Glp-1 fragment 7-36 was cosynthesized with the dimer, the antibacterial peptide derivative lost its ability to cross the bacterial membrane layer. In contrast, a chimera of the Pip-pyrr-MeArg dimer and two copies of a shorter (nine residues) class I major histocompatibility complex epitope successfully entered bacterial and mammalian cells. While the Pip-pyrr-MeArg dimer was not immunogenic when inoculated into mice, the chimera elicited a strong cytotoxic T-cell response, indicating the maintenance of the antigenic integrity of the cargo in the peptide conjugate. The chimera when tested for its immunological properties activated human dendritic cells significantly more strongly than any of the two independent fragments alone, yet lacked mammalian cell toxicity. These results confirm the utility of designed pyrrhocoricin analogues for delivery of peptidic cargo across cell membranes in general, and their potential as carriers for epitope-based vaccines in particular.
Collapse analysis of reinforced concrete frames including bar fracture
Publisher: SAGE Publications
Date: 02-2016
Abstract: A nonlinear one-dimensional compound frame element is formulated and applied to collapse analysis of reinforced concrete frames including fracture of longitudinal reinforcing bars. The proposed formulation can take account of geometrical and material nonlinearities including cracking and crushing of the concrete, yielding of steel bars, post-yield tension stiffening and fracture of reinforcing steel bars and fixed-end rotation. The material nonlinearities are formulated within the framework of a distributed nonlinearity model, and the rupture of reinforcing bars is captured by nodal springs with damage multipliers. The developed analytical tool is verified against available experimental data in the literature. It is shown that the developed compound element and proposed modelling strategies can capture the full load–deflection response and the ultimate loading capacity of reinforced concrete beam assemblages/frames subjected to large displacements.

Model error and reliability of reinforced concrete beams in shear designed according to the Modified Compression Field Theory
Publisher: Wiley
Date: 20-10-2021
Abstract: Model error (or model uncertainty) were probabilistically characterized for modified compression field theory (MCFT) Simplified and General Method approaches using experimental databases that contained reinforced concrete (RC) beams having shear failures with and without stirrups (168 and 368 specimens, respectively). It was found that when compared to the design shear model currently used in ACI‐318, the General Method produced low model error variability indicating better consistency for the determination of shear strength. Structural reliabilities were then calculated for RC beams in shear designed to MCFT General Method (AASHTO LRFD, CSA A23.3‐14, AS3600‐2018) for a live‐to‐dead load ratio between 0 and 5, and for capacity reduction factor ϕ = 0.70, 0.75, and 0.80. It was concluded that the ϕ ‐factor for shear failure for Australian standards can be increased from 0.70 to 0.75 for RC beams with stirrups, providing a 7.1% increase in the design shear capacity and contributing to sustainable design and reduction in greenhouse gas emissions due to more efficient usage of materials.

Abstract: The ability of antigens to elicit immune responses depends upon their initial recognition, uptake, processing and presentation by dendritic cells. This fact has been recognized by many workers and dendritic cells are now regarded as natural 'adjuvants' in the business of vaccine design. One way of persuading dendritic cells to become interested in foreign material is to decorate it with lipid moieties found in bacteria. This approach has been used in the context of synthetic peptide-based immunogens and depending on the nature of the epitopes included, can provide highly immunogenic structures capable of eliciting antibody or cytotoxic T cell responses. In this paper we describe the results of experiments in which the stimulatory effects of peptide-based vaccine candidates on human dendritic cells are examined. Our findings indicate that lipidated structures comprising vaccine target sequences of viral origin coupled to the synthetic lipid groups of bacteria are able to induce the maturation of dendritic cells, as measured by the expression of cell surface MHC class II molecules.

Abstract: As part of an ongoing research project into the numerical prediction of high temperature hygral processes in concrete and fire induced spalling, a fully coupled hygro-thermal model has been formulated for predicting the behaviour of concrete at high temperatures. The hygro-thermal model is a mathematical model for predicting the behaviour of concrete at high temperatures, treating the concrete as a multi-phase semi-saturated porous material. A numerical simulation of a one-dimensional heating experiment performed on an unreinforced concrete slab is presented, demonstrating the effectiveness of the model. A brief discussion of the main hygral processes is presented, in addition to a discussion of numerical challenges arising from the numerical implementation.

The efficiency of recycled glass powder in mitigating the alkali-silica reaction induced by recycled glass aggregate in cementitious mortars
Publisher: Springer Science and Business Media LLC
Date: 29-06-2022
DOI: 10.1617/S11527-022-01989-7
Abstract: With the potential for a decline in fly ash (FA) production over time, due to the phasing down of coal fired power plants, alternative supplementary cementitious materials need to be identified. The efficiency of pulverised glass powder (PGP) was studied for its reactivity and its capacity for inhibiting alkali-silica reaction (ASR) that results from utilisation of recycled glass as a fine aggregate (sand) replacement. Characterisations of pastes containing PGP reveal that PGP may possess latent hydraulic properties, resulting in a more than 75% strength activity index, together with better strength gain than FA-blended pastes. PGP also offered increased heat of hydration compared to FA, from a combination of the dilution effect, filler effect and early-age reactions of PGP. A comparable efficiency of PGP and FA in ASR expansion mitigation was confirmed with mortar bar expansions of less than 0.10% at cement replacement levels of at least 10%. Both PGP and FA provided alkali dilution and reduced the mass transport in hydrated cement paste from the refinement of larger pores to below 60 nm. The FA mix consumed calcium hydroxide and, thus, performed marginally better than the PGP mix in mitigating ASR. This pozzolanic reactivity is not evident for PGP, whereas in the literature glass powders are often regarded as pozzolanic. Microscopic images confirm that PGP and FA significantly limit the occurrence of ASR gels without altering its composition. It was concluded that PGP is a comparable ASR inhibitor to FA, despite the underlying differences in their mechanisms. The result of this research support the utilisation of recycled glass both as an aggregate, and as an ASR-inhibiting SCM in cementitious systems.

Fibre-reinforced concrete beam assemblages subject to column loss
Publisher: Thomas Telford Ltd.
Date: 03-2016
Abstract: Application of steel-fibre-reinforced concrete (SFRC) to partially replace conventional steel reinforcement, particularly the stirrups in beams, has found increasing use in practice. However, the collapse response of SFRC beams (with no stirrups) subject to column loss scenario has not been investigated. Accordingly, four 2/5th scale beam sub-assemblages with SFRC and no stirrups are constructed and tested under a column loss scenario and the potential for steel fibres to replace the stirrups is investigated. The experimental results show that the use of structural steel fibres as a replacement for stirrups has a minor influence on the membrane behaviour of beams as well as the robustness of SFRC frames subjected to column loss. In addition, detailed finite-element models of the assemblages are developed and validated against the experimental data and the validated models are used to investigate the influence of steel bar ductility on the ability of beams to develop tensile membrane action. It is concluded that the minimum ductility requirements adopted by the Australian standard for normal ductility reinforcing bars (minimum uniform elongation of 0·05) is not sufficient to allow full development of catenary action in reinforced concrete/SFRC beams.
