 Early-strengthening Water-reducing AgentsvYEGM环氧树脂灌浆料_SPC聚合物修补砂浆_防碳化涂料厂家
　　 A5 High-efficiency, early-strengthening. Water-reducing agent has, for its main ingredient, β-naphthalenesulfonis acidformaldehyde high condensate, which is compounded with the high-efficiency, early-strengthening, water-reducing agent that strengthens the cementitious composition. It is adaptable to all types of cement. With little air induced; its water reduction and gain in strength are remarkable, especially, its early strength is very notable. It can raise the resistance to frosting and seeping, and it can last longer, the product has been manufactured in compliance with relevant national standards for additives.svYEGM环氧树脂灌浆料_SPC聚合物修补砂浆_防碳化涂料厂家
