为了解决普通混凝土存在的干缩开,从而发生渗漏的难题,建筑材料科学研究院进行了长期研究与实践,认为采用膨胀水泥或膨胀剂拌制的补偿收缩混凝土,可在钢筋和邻位约束下,导入2-10kgf/cm~2自应力,大大提高混凝土的抗裂性。同时,具有优良的抗渗性。 U型混凝土膨胀剂(简称UEA)是由建筑材料 In order to solve the problem of leakage of dry shrinkage of ordinary concrete, the Institute of Building Materials Science has conducted long-term research and practice, and believes that the compensation shrinkage concrete mixed with expansion cement or expansion agent can be restrained in the reinforcement and adjacent locations. Next, introduce 2-10kgf/cm~2 self-stress to greatly improve the crack resistance of the concrete. At the same time, it has excellent impermeability. U-type concrete expansion agent (abbreviated as UEA) is made of building materials
