Use of Water Reducers, Retarders, and Superplasticizer

Admixtures are used to modify the properties of concrete or mortar to make them more suitable to work by hand or for other purposes such as saving mechanical energy. Water reducing admixtures (WRA) 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

What are water-reducing admixtures?

A. Water-reducing admixtures are used to increase the strength and workability of concrete and to reduce cost. They. consist of certain organic compounds or mixtures of organic and inorganic compounds to reduce the water requirement of the mixture for a given slump. Reduction in water demand may result in a reduction in the w/cm for a given ...
