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
