definition

edit

Polymer mortar is made by mixing cement, aggregate and organic polymer that can be dispersed in water. Polymers can be homopolymers polymerized by one monomer, or copolymers polymerized by two or more monomers. polymer Film must be formed to cover the cement particles under environmental conditions, and make the cement body form a strong bond with the aggregate. The polymer network must have the ability to prevent the occurrence of micro cracks and prevent the expansion of cracks.^[1]
