摘要：

The effect of the ground granulated blast-furnace slag （GGBFS） addition, the modulus n （ mole ratio of SiO2 to Na2O） and the concentration of sodium silicate solution on the compressive strength of the material, i e alkali-activated carbonatite cementitious material （AACCM for short） was investigated. In addition, it is found that barium chloride has a satisfactory retarding effect on the setting of AACCM in which more than 20% （by mass） ground carbonatite was replaced by GGBFS. As a result, a cementitious material, in which ground carbonatite rock served as dominative starting material, with 3-day and 28-day compressive strength greater than 30 MPa and 60 MPa and with continuous strength gain beyond 90 days was obtained.
