Water retaining admixtures
Admixtures for concrete; Material added during the mixing process of concrete in a quantity not more than 5 % by mass of the cement content of the concrete, to modify the properties of the mix in the fresh and /or hardened state. Water resisting admixture; Admixture which reduces the loss of water by a reduction of bleeding.
