Flow time analysis of blended mixes using Marsh cone apparatus (original) (raw)

Admixture-Cement interaction in concrete is a complex blend of chemical and physical mechanism that are independent. Every admixture at optimum dosage gives better results when used with cement. The proposed research is aimed to study the compatibility of super plasticizer with different types of blended cements by investigatingflow time value. The present work is to study the behaviour of blended mixes (OPC+GGBS+ALCCOFINE) with the PCE (poly carboxylic ether) based admixtures at various dosages of both GGB,ALCCOFINE and chemical admixture. It was observed that most of the blended mixes were compatible with PCE based admixtures at dosages of around 3%. Increase in flow time has been observed with the addition of ALCCOFINE.
