Cementitious Coatings for Concrete Surfaces: Effects of Curing Conditions on Performance Measure
To increase cohesiveness, toughness, impermeability, and adhesion strength in cementitious materials like mortars and concrete, vinyl acetate ethylene (VAE) copolymer redispersible powder (RDP) is used. However, due to numerous variety of material, choosing an original performing RDP is challenging. The goal of this study is to assess the bond strength to concrete surfaces of various redispersible polymer-modified cementitious coatings under various accelerated settings. The outcomes showed that the RDP backbone composition has a significant influence on the coatings' adhesion strength. Methyl methacrylate (MMA) and Vinyl chloride (VC) present as comonomers in RDP exhibit outstanding thermal stability and boost tensile adhesion strength by 41% and 21%, respectively, in comparison to other RDPs. According to SEM studies, the VC- RDP stimulates the formation of fibrous ettringite, producing a uniform and cohesive microstructure.
