What are water
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

How to Reinforce Concrete
May 03, 2021Concrete naturally loses water over time, which causes it to shrink and thus become weaker. Pour shrinkage-reducing admixture into your concrete, per the manufacturer's instructions, to prevent cracking or curling caused by this water loss. You can purchase shrinking-reducing additives at any store that sells concrete mixtures.
