Abstract

Experimental results about effect of superplasticizer dosage, fly ash content and water to cement ratio on rheology and setting time are presented. 16 samples are evaluated using a Brookfield laboratory rheometer and a standard vicat needle apparatus. Spread of the samples is also measured using mini slump cone (d1=60mm, d2=35, h=60mm) and an empirical relationship between spread and yield stress is put forward.
