Durability of cement pastes modified by polymer dispersions

Synchronous Monitoring of Cement Hydration and Polymer Film Formation Using 1H-Time-Domain-NMR with T2 Time-Weighted T1 Time Evaluation: A Nondestructive Practicable Benchtop Method

“…Polymer latex, which is also called polymer dispersion, can be applied as dispersions or dried redispersible powders and can significantly improve cement-based mortars, such as repair mortars, self-leveling underlayment, renders, tile adhesives, waterproofing membranes, and more. The use of polymer dispersions leads to a significant improvement in necessary properties such as adhesive strength, flexural strength, workability, or durability. , …”

“…The use of polymer dispersions leads to a significant improvement in necessary properties such as adhesive strength, flexural strength, workability, or durability. 2,3 The combination of cement and polymer latex leads to a very complex composite with a hardening process that can be divided into a chemical reaction (hydration of cement) and a physical coalescence of polymer particles caused by the interdiffusion of the polymer chains between the single polymer particles, which is known as film formation. During the composite/hybrid formation process, the cement consumes water, starts hydration, and builds new mineral phases.…”
