Title: Preparation of cementitious materials with environment-protecting high performance
Abstract: To develop a kind of high performance cementitious material which contains less cement,its theory foundation and techno-approach were studied.The key technology is that the components of the cementitious material should be selected rightly and its input-quantity should be optimized combining with the mill-activation technology to increase the hydration-degree of the cement.According to the theory upwards,some experiments were performed to make the environment-protected high performance cementitious material(EHPCM).A proper cementitious system was selected,the proportion of components in cementitious system was optimized so that a kind of EHPCM was made.Theory calculation and experiment results show that the four-dimension cementitious system with an activate technique has characteristics of low cement content and high hydration degree,which can be used to make EHPCM.The reactived powder concrete whose compress strength is 132 MPa and the flexural strength is 18 MPa is made using the cementitious materials developed in the experiment.
