Anti-Washout/Rheology Modifying Admixture

EUCON AWA-P20 is a ready to use liquid admixture designed to modify the rheology of self consolidating concrete and prevents the loss of cement and fine aggregate during the placement of underwater concrete. EUCON AWA-P20 also can be used to reduce excessive bleeding and segregation of concrete or mortar. The Euclid Chemical Company recommends the use of EUCON AWA-P20 with the PLASTOL line of polycarboxylate based admixtures. EUCON AWA-P20 contains no added chlorides or chemicals known to promote the corrosion of steel.
