This project seeks to develop a new class of building materials based on geopolymers. These materials will have superior corrosion resistance, fire resistance, heat and noise insulating properties. The project will study in detail the effect of processing parameters on microstructure of these materials, and effect of structure and composition on properties. A good understanding of this would result in environmentally friendly inexpensive inorganic materials with superior durability, chemical and fire resistance, heat and noise insulation properties that can substitute organic polymers and ordinary Portland cement concrete in special applications.Read moreRead less
Effect of processing on microstructure of 'Biocrete' organo-mortar. 'Biocrete' is a novel organo-mortar whose composition differs substantially from conventional Portland cement based polymer mortars. It is a relatively new product with significant commercial potential because of its acid resistance and ease of application. However, the microstructure of this material is extremely complex and not well understood nor is the way the microstructure develops during the processing and application of ....Effect of processing on microstructure of 'Biocrete' organo-mortar. 'Biocrete' is a novel organo-mortar whose composition differs substantially from conventional Portland cement based polymer mortars. It is a relatively new product with significant commercial potential because of its acid resistance and ease of application. However, the microstructure of this material is extremely complex and not well understood nor is the way the microstructure develops during the processing and application of the material known. This project will use advanced materials characterisation methods to elucidate the microstructure and to quantify the effects of processing parameters on the microstructure. Such information is critical for further formulation and application development in important areas such as sewer relining.Read moreRead less
Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual defl ....Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual deflection leading to serviceability problems. The significance of this investigation hence lies in its potential to provide a solution to more accurately predict service-life deflections in post-tensioned concrete suspended slabs and validate the model with real-life deflections monitored over time on a current building project.Read moreRead less

By fully taking advantage of excellent affinity of water with polar layered silicate and polar polymer, an innovative approach to fabricate thermally stable polymer/layered silicate nanocomposites via melt extrusion with the aid of water/water vapour will be developed. In this process, the pristine layered silicate will be directly exfoliated into individual layers with nanometer thickness and high aspect ratio, and uniformly dispersed in a polymer matrix. This novel approach is environmentally benign and cost-effective since no alkyl ammonium surfactants are required. The resultant nanocomposites will exhibit excellent barrier properties, high thermal stability, environmental durability and superior mechanical properties. These qualities make them very attractive for many applications in the automotive and packaging industries.Read moreRead less
Ceramic matrix nanocomposites. Using a novel process developed by the applicant, this project will create and study ceramic matrix nanocomposites of two types: (i) those in which the nanoparticles are homogeneously distributed in alumina and (ii) functionally-graded nanocomposites of controlled heterogeneity, that is, nanocomposites in which the nanoparticles are distributed heterogeneously in glass.

Homogeneous nanocomposites of alumina are potentially of great importance to the mining industry as they can increase the toughness and wear resistance of mining components. Heterogeneous nanocomposities have the potential to revolutionise the dental restoration industry by combining greatly increased toughness with the aesthetic benefit of controllable translucency.Read moreRead less
Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous ....Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous and complicated form of corrosion. Existing experience indicates that EAF incidence will increase as magnesium alloys are increasingly used in more challenging applications. The results and insights from this research will help to underpin a major new industry and industrial applications.Read moreRead less
