| Abstract |
The purpose of this study was to present surface adhesion characteristics of inorganic fiber-reinforced cement composite based on the results of experiment on the cement composite by the interfacial agent for the inorganic fiber PAM (Polyacrylamide). To improve surface adhesion between the inorganic fiber and cement in the inorganic fiber-reinforced cement composite, N-PAM (Nonion), C-PAM (Cation) and A-PAM (Anion), etc. were used as interfacial adhesives. Analysis of the physical properties of inorganic fiber-reinforced cement composite showed that C-PAM adhesive is an optimal interfacial treatment agent for the carbon fiber, whereas A-PAM adhesive is optimal for the epoxy coating carbon fiber. The excellent interfacial adhesion and physical properties of the cement composite were likewise revealed. Besides, the study of the tensily crushed cross section of the cement composite showed that the cement composite using interfacial treatment of the inorganic fiber manifests excellent refinement in the inner structure and interfacial adhesion, along with improved relevant physical properties. Results showed that the epoxy coating carbon fiber has better interfacial adhesion than the carbon fiber. When interfacial adhesion is reinforced by the interfacial adhesive for inorganic fiber, C-PAM was found to be suitable for the carbon fiber, whereas A-PAM adhesive was suitable for the epoxy coating carbon fiber. Analysis of the physical properties of inorganic fiber-reinforced cement composite showed that the epoxy coating carbon fiber has stronger interfacial adhesion to the cement interfacial structure, and better physical characteristics and mechanical properties than the carbon fiber. |
