Abstract：The effects of mixing water temperature and external reinforcing materials（rubber powder，polypropylene fiber and expanded vermiculite） on the physical and mechanical properties of foamed cement were studied emphatically through experiments. Considering the pore size structure，compressive strength and flexural strength, the optimum mixing water temperature and the optimum mixing amount of rubber powder，polypropylene fiber and expanded vermiculite for 250 kg/m3 foamed silica cement were proposed.
