摘要
以氨基磺酸系高效减水剂对水泥净浆流动度 ,混凝土力学性能、膨胀性能、坍落度损失等方面的研究表明 ,氨基磺酸系高效减水剂对水泥具有高度的减水作用 ,以它为主要成分的混凝土外加剂 ,可以大幅度提高混凝土的强度 。
It is studied that sulfamic acid series sup er plasticizers to cement paste flowability,concrete performance of mechanical,dist e nsibility and slump loss of concrete.It shows sulfamic acid series superplastici z ers have high water-reducing,concrete additive mainly composed with it can consumedly improve intension of concrete and preferable ameliorate concrete cap ability.
