Abstract

Use of Self-compacting concrete (SCC) in construction industry makes heavily congested reinforced area easier by avoiding vibration and reduces the time of construction, labor requirement and equipment on construction sites, noise reduction due to vibration, and better surface finishing. However, use of SCC is limited because it requires more binder content, chemical admixtures as cost is higher as compared to conventional concrete. SCC can be cost effective and eco-friendly by addition of mineral admixture as a partial replacement to cement and is the way to reduce the binder content. However, the durability of such SCC needs to be proven. In the present investigation, effect of freezing and thawing on quaternary blended SCC were found for different water binder ratio and compared with control self compacting concrete. The result shows that the effect of freezing and thawing was reduced on quaternary blended self compacting concrete with control self compacting concrete.
