Development of thin bed concrete masonry structural walls. Masonry is one of the most well regarded construction systems for low and medium rise buildings, but requires skilled labour. The current skills shortage incurs project delays, leading to direct and indirect costs to the Australian community. Thin bed technology for concrete masonry will utilise special blocks and binders for easy adoption by unskilled labour, without compromising personal safety or structural integrity. As thin bed wal ....Development of thin bed concrete masonry structural walls. Masonry is one of the most well regarded construction systems for low and medium rise buildings, but requires skilled labour. The current skills shortage incurs project delays, leading to direct and indirect costs to the Australian community. Thin bed technology for concrete masonry will utilise special blocks and binders for easy adoption by unskilled labour, without compromising personal safety or structural integrity. As thin bed walls require less volume of cement reduced binders, the technology will also lead to reduced carbon emission. Thus, this project addresses two of Australia's greatest challenges: environmental degradation and our critical skills shortage.Read moreRead less
INVESTIGATION OF THE MECHANISM CAUSING SHRINKAGE STRAINS IN CONCRETES MADE WITH SLAG BLENDED CEMENTS. Slag, an industrial by-product, can partially substitute portland cement. High slag contents produce highly durable concretes and help reduce the CO2 emissions due to cement manufacture. Major problem of high slag content is often the high shrinkages resulting in the concrete. This project will systematically study all the factors affect the shrinkage behaviour in slag-blended cement concrete ....INVESTIGATION OF THE MECHANISM CAUSING SHRINKAGE STRAINS IN CONCRETES MADE WITH SLAG BLENDED CEMENTS. Slag, an industrial by-product, can partially substitute portland cement. High slag contents produce highly durable concretes and help reduce the CO2 emissions due to cement manufacture. Major problem of high slag content is often the high shrinkages resulting in the concrete. This project will systematically study all the factors affect the shrinkage behaviour in slag-blended cement concretes including the appropriateness of the standard shrinkage measurement method. The other aim is to develop a micro-mechanical model to understand the fundamental mechanism involved. This model will also lead to a better understanding of the mechanisms involved in shrinkage in all concretes.Read moreRead less
