Abstract

This paper presents an experimental investigation on the effect of alternate wetting and drying on the properties of SCC produced by the combination of admixtures such as (Superplasticizer + Viscosity modifying admixture +Air entraining agent + Accelerator), (Superplasticizer + Viscosity modifying admixture+Air entraining agent +Retarder), (Superplasticizer + Viscosity modifying admixture +Air entraining agent + Water proofing compound) and (Superlasticizer + Viscosity modifying admixture +Air entraining agent + Shrinkage reducing admixture).The specimens were subjected alternate wetting and drying for 45 cycles and 60 cycles. Resistance of SCC containing the above combination of admixtures is found to be satisfactory for alternate wetting and drying.SCC show lesser resistance when it is subjected to 60 cycles of alternate wetting and drying as compared to 45 cycles of alternate wetting and drying. SCC produced with above combination of admixtures show better resistance to alternate wetting and drying as compared to SCC produced with combination of admixtures (SP+VMA) only.
