高强膨胀剂是最新科研成果,在制备混凝土时掺入6%～12%的高强膨胀剂,代替相同重量水泥,制成的混凝土其强度比一般膨胀剂混凝土强度提高10MPa左右;抗渗标号提高10%～20%适宜在要求高强度和抗渗的工程中使用。该产品经北京、山东、上海等重大工程中使用,效果良好,深受用户好评。1 High-strength expansive agent is the latest scientific research, in the preparation of concrete mixed with 6% to 12% of high-strength expansive agent, instead of the same weight of cement, concrete strength than the general expansion agent concrete strength increased about 10MPa; % ~ 20% Suitable for use in projects requiring high strength and impermeability. The product by Beijing, Shandong, Shanghai and other major projects in use, the effect is good, praised by users. 1
