我厂用CaO含量50%以上、MgO含量30%左右的白云石,在900～1200℃煅烧所得的白云石质石灰作激发剂,生产石膏矿渣水泥,其配合比为:水淬矿渣:无水石膏:白云石质石灰=82.5%:16%:1.5%,生产出的水泥安定性良好,1∶3硬练砂浆28天的耐压强度达678公斤/平方厘米,28天抗拉强度47.27公斤/平方 Our factory uses dolomite with a CaO content of over 50% and a MgO content of around 30%. The dolomite lime calcined at 900-1200°C is used as an activator to produce gypsum slag cement. Its mixing ratio is: water quenched slag: anhydrous Gypsum: Dolomite lime = 82.5%: 16%: 1.5%, the cement produced has good stability, the compressive strength of 1:3 hard mortar for 28 days is 678 kg/cm2, and the tensile strength for 28 days is 47.27 kg /square
