Abstract

The possibility of using mineral admixtures as a replacement for cement may reduce the carbon dioxide emission, which causes global warming and climatic changes on the environment. The objective of this study is to investigate the properties of early strength concrete produced with a constant replacement of alccofine (i.e. 25% by mass) and a new generation of chemical admixture that is Polycarboxylate ether. The constant dosage of alccofine and different proportions of polycarboxylate ethers are mixed in concrete and tested for workability and mechanical properties of concrete. Response surface method was applied to predict, validate and optimize the experimental data using regression equation. The results show that the performance of concrete improves with the addition of alccofine and Polycarboxylate ether into concrete.
