Effect of PVA Modificatio on the Properties of Cement Composites
Original language description
Polymers have been used for modifying cement-based composites and other building materials since the 1930s. Recent studies have assumed that even water soluble polymers can be used as an admixture for a modification of this kind. Several ways for modifying mortars, wood-based products and bituminous asphalts with a polymer are known and are currently being exploited. Various options differ in the way in which the modification is made. It can be applied basically to the entire volume or just to a surface, and the polymer can be used in the form either of a solution or of fibers. The aim of our study was to investigate the influence of modifying the volume with water soluble polymers, such as polyvinyl alcohol (PVA), on the properties of a cement paste,and to find an optimal additive. It turned out that the addition of a PVA solution into fresh cement paste increases the porosity and therefore reduces the stiffness and the compressive strength. However, the bending strength of PVA-rich
