Department of Materials Science and Engineering, Zhejiang University, Hangzhou 310027; 2.Hangzhou Hongtu Pile Manufacturing Co. , Ltd,Hangzhou 311228, China) Abstract The characters of pore structure of the cement stone containing slag and containing fly ash are investigated in this paper. The results show that the cement stone containing fly ash has higher porosity but smaller pore radii distribution, having more porosity with pore radii under 5nm and less over 5nm.
