摘要: AbstractThe results of an experimental program conducted on latex-modified mortars are presented in this article. These have become growing interest the field construction. They were used as superplasticizers, or water reducers, for finishing work applications and repairs, coatings, waterproofing. This study is about using two polymers (latex), i.e. styrene–butadiene rubber styrene–acrylic, order to assess their performance replacing cement mortars. A series mortar mixtures, containing 0, 2.5, 5, 10, 15, 20% solid polymer latex (by weight), prepared tested fresh hardened states. The test parameters include fluidity, compressive flexural strengths, porosity accessible water, adhesion clay bricks, cementitious substrates. showed that substituting into modified improves fluidity adhesion. In case substrates, a cohesive failure occurs within substrate layer be...
