In this work 4 superplasticizers were used and on the basis of the workability test on cement paste two SP's were selected for further studies and to compare their effects on mortar properties such as workability, compressive strength, water reduction and tensile strength. Two different mortar mixes (1:1.5 & 1:2) were tested for three values of w/c ratio (0.3, 0.35, and 0.4) for varying SP dosage i.e. from 0.6 to 2%. This paper presents an experimental investigation on strength aspects such as

The methodology adopted is that Portland cement is replaced by 0%, 35% and 50% of fly ash using two types of superplasticizers (SNF, PCE) and performance is measured and compared. Further Design of Self Compacting Concrete by replacing Fly ash is proposed and the studies on fresh and hardened properties were conducted. The results showed that PCE type Superplasticizer is performing better than SNF type in terms of workability.
