Product description:
High-efficiency water reducer is also called superplasticizer. It is different from ordinary water reducer in that it has a high water reduction rate. The water reduction rate of ordinary water reducer is generally 5%-10%, while the water reduction rate of high-efficiency water reducer can reach 15%-30%. Moreover, high-efficiency water reducer can be added to cement in a higher proportion without adverse effects on concrete. High-efficiency water reducer is divided into melamine water reducer and polycarboxylic acid water reducer. SMF is a melamine-type sulfonated polycondensate powder made by spray drying process. It has excellent fluidity and construction properties and is particularly suitable for plasticization and water reduction of cement-based and gypsum-based dry powder products. It has a very good dispersing effect on cement, volcanic rock and filler, and can produce a completely uniform and non-segregated mortar or grout mixture. The use of SMF can reduce the amount of water used for mixing and thus improve strength.
