Use of Water Reducers, Retarders, and Superplasticizer

The use of WRA is defined as Type A in ASTM C 494. WRA affects mainly the fresh properties of concrete by reducing the amount of water used by 5% to 12% while maintaining a certain level of consistency, measured by the slump as prescribed in ASTM C 143-90. The use of WRA may accelerate or retard the initial setting time of concrete.

The concrete incorporated a 30% replacement of the total powder content by limestone filler. The degree of drop in slump flow consistency of the mortar with the increase in VEA content was especially high for the bio-gums. On the other hand, the cellulose-based VEA had a rather limited effect on reducing fluidity, despite the high addition rate.
