Microstructure and Finite Element Analysis about Ceramic Concrete after High Temperature

This paper researched the high temperature properties of ceramic concrete though experimental. Test and analysis on the microstructure between the ceramic concrete and ordinary concrete which experience different temperatures using scanning electron microscopy (SEM); and analysis on the high temperature performance of the ceramic concrete using finite element method The results show that: the C-S-H gel, Ca (OH) (2) crystals and the interfacial transition zone between aggregate and colloidal and other microstructure have different characteristics, these features can be used to explain the main reasons for changes of the concrete performance indicators after the high temperature and to provide technical basis for the application of ceramic concrete in the high temperature environment.
