Abstract

Generally SCC requires a large content of binder and chemical admixtures compared to ordinary concrete; its material cost is generally 20-50% higher, which has been a major hindrance to a wider implementation of its use. There is growing evidence that incorporating high volumes of mineral admixtures and micro fillers as partial replacement for Portland cement in SCC can make it cost effective. However, the strength and durability of such SCC needs to be proven. Compared to normally vibrated concrete, self-compacting concrete possesses enhanced qualities and improves productivity and working conditions due to elimination of compaction. SCC generally has higher powder content than Normally Vibrated Concrete (NVC) which can increase cost and also cause temperature rise during hydration as well as possibly affect other properties such as creep and shrinkage, thus it is necessary to replace some of the cement by additions to achieve an economical and durable concrete.
