Abstract –Mineral admixtures (supplementary cementitious material) and chemical admixtures are used extensively in modern concrete to achieve specific concrete properties more effectively and ensure quality of concrete during mixing, transporting, placing and curing. The aim of this experimental work is to study the effect of combination of admixtures on properties of the GGBFS and Metakaolin based concrete. The parameters that are varied in the experiment includes two concrete mixes with partial cement replacement of 20% by GGBFS and Metakaolin respectively and the four combination of admixtures selected are superplasticizer + retarder, superplasticizer + acclerator, superplasticizer+ water proofing admixture and superplasticizer + Viscosity Modifying agent.Experiments are conducted to determine workability ,strength and durability characteristics of concrete.

Key words –Metakaolin; GGBFS; Chemical

Admixtures,Mineral Admixtures
