Effect of Adding Redispersible Polymer Powder to Cementitious Tile Adhesive: A Literature Review

Modern advancements in structural and construction materials have prompted researchers to focus on the adaptation of these innovations. Particularly, ceramic tiles have garnered attention due to their aesthetic appeal in various indoor and outdoor settings, alongside their simplicity of installation. The utilization of ceramic tiles isn't only geared towards providing structural integrity, but similarly towards enhancing their visual attributes, which hold significant value. In terms of affixing these tiles onto surfaces, the conventional approach entails the employment of sand-cement grout. Nonetheless, this method presents certain limitations such as inadequate water retention, rigid surfaces, extended drying periods, lack of pliability, and thicker paste application, among other issues. These obstacles can be effectively addressed through the incorporation of redispersible polymer powder (RPP) in conjunction with additional cementitious elements. Through their combined application, polymers synergize with cement constituents to bolster physical and mechanical characteristics, thereby improving adhesion strength, minimizing shrinkage, and reducing water absorption. The main goal of this review article is to highlight the significance of ceramic tile adhesive while offering a thorough explanation of cementitious tile adhesive (CTA) and all of its components. We focused emphasis on the commercially available RPP and its incorporation into CTA formulation.
