| Abstract: | The raw and processed materials,design of the mixture ratio,property and contractibility of micro-expansive concrete are stutied.The high-powered concrete which is mixed with powdery cinders according to the design is compounded based on the optimization of the mixture ratio,and the property of mixtures,physical and mechanical property and deformation property of the compounded concrete are investigated.The relation between the experimental data of self-expansive volume of micro-expansive concrete and the computational model of micro-expansive concrete is analyzed objectively. |

| Keywords: | micro-expansive concrete mixing ratio physical and mechanical property deformation property self-stress |
