摘要

Physical and chemical properties of ultra-fine composite cement M applied in conerete with superplasticizer are introduced in this article. The hydration products and microstructure of cement M are studied by using SEM, XRD, DTA. It is characterized by high early strength and good abrasion. It also has good compatibility with naphthalene or amido sulphonate series superplasticizer. It can be used for preparing premixed concrete and high-strength concrete. Its main shortcoming is higher water demand due to higher specific surface.
