The Function Mechanism of Redispersible Polymer Powder
There are different views on the interaction between polyvinyl acetate and cement in aqueous solution. Some scholars think that the modified cement mortar with polyvinyl acetate itself forms polymer film inside and the holes inside mortar are sealed or covered, so its impermeability is improved. Foreign scholars think that the interaction between polymer and Ca(OH)2 … Continue reading
