Answer :

Significance of water reducing admixture in concrete: Water reducing admixtures are essential for several purposes. The effect of using such admixtures on concrete properties is described below. 1. Water reducing admixtures maintain required w/c ratio by reducing excess water upto 10-30% from concrete. 2. These admixtures are significant in preventing segregation of concrete mixture and maintaining flow ability of pumped concrete. 3. Mid-range water reducing admixtures are important to increase workability in terms of slump beyond the regular water reducers. 4. Water reducing admixtures reduces the tendency of surface cracking. 5. It also ensures the good bonding between steel and concrete mass. 6. These admixtures help to increase early strength and develop better ultimate strength. 7. The durability of concrete structures can be ensured by using these admixtures.
