Introduction to polymer cement mortar
Polymer cement mortar is a composite material made by combining cement, aggregates, and organic polymers that can be dispersed in water. These polymers can either be homopolymers, formed from a single monomer, or copolymers, created through the polymerization of two or more different monomers. In order to function effectively, the polymer must form a continuous film under environmental conditions, coating the cement particles and creating a strong bond between the cement matrix and the aggregate. This film helps improve adhesion, flexibility, and durability. Additionally, the polymer network plays a crucial role in preventing the formation of microcracks and limiting their propagation, which enhances the overall performance and longevity of the mortar. By incorporating these polymers, the material becomes more resistant to cracking, moisture, and mechanical stress, making it suitable for a wide range of construction applications.
