Abstract

Blended cements are noticed as countermeasure for the reduction of produced CO₂ gas in production of cement. This paper described the influence of the various type of additive on the hydration and chemical shrinkage of blended cement. The chemical shrinkage of BFS Cement was larger than OPC or other blended cements after 3 days. BFS rapidly reacts compared with the case of other additives. Chemical shrinkage of FA cement is indicated the smallest values, it is because FA didn’t react until 7 days.
