Abstract:Physical and chemical properties of ultra fine composite cement M and its compatibility with superplasticizer were studied. The hydration products and microstructure were studied by using SEM, XRD, DTA. Test results show that the cement M has high early strength, normal strength development and good abrasion resistance. It also has good compatibility with naphthalene or amino sulphonate series superplasticizer, and can be used for making ready mix concrete and high strength concrete. Its main shortcoming is higher water demand due to the higher specific surface areas.
