Film Formation: During the cement hydration process, the latex powder particles absorb water and disperse; upon the evaporation of the water, they form a continuous polymer film.
Interface Modification: The polymer film encapsulates the cement hydration products, thereby improving the interfacial bonding between the aggregates and the cementing matrix.
Filling Effect: The latex powder particles fill the internal pores within the cement-based material, refining the pore structure and enhancing its compactness.
