A complex analysis of properties of sulfoaluminate cement containing natural zeolite as supplementary cementitious material in an amount of up to 30% by mass is presented.The studied parameters include compressive strength,alkalinity of pore fluid, water-holding capacity, open porosity, the products of hardened calcium sulfoaluminate cement.Experimental results show that 10% zeolite can increase the conpressive strength sulfoaluminate cement, the conpressive strength of 3d hydrated sulfoaluminate cement (containing 10% zeolite by mass) paste up to 63Mpa.While the dosage of zeolite for 30% by mass, the alkalinity of pore fluid of hydrated sulfoaluminate cement paste is 10.3.The water absorption amount of hydrated cement pastes changed great within the initial 0.5h..A large amount of zeolite powder can increase water absorption capacity of hydrated sulfoaluminate cement paste.While the dosage of zeolite for 30% by mass, the water absorption is 11%.
