Rheomac 730 

RHEOMAC 730 is a hydrophobic pore-blocking ingredient (H.P.I) for concrete. It significantly reduces water absorption of concrete.

RHEOMAC 730 is a chloride free organic admixture and supplied as a brown liquid. It reacts with the cement hydration process to form a hydrophobic ingredient to reduce the capillary suction and prevent the ingress of potentially deleterious soluble material, resulting in concrete with enhanced durability.
