摘要 采用石灰石、硬石膏、粉煤灰、硅石为原料,研究了固定铝硫比(P=3.82)条件下,氧化铝含量为10%时,碱度系数和煅烧温度对CaO-SiO2-Al2O3-Fe2O3-SO3系统水泥熟料矿物烧成的影响。结果表明,碱度系数为1.2,煅烧温度范围为1375~1425℃时制得的水泥为高贝利特硅酸盐水泥;C4A3S分解生成了C3A,而非C12A7;在SO3和C3A存在的条件下,促进C3S在低温下形成,部分C3S在高温下分解为α'-C2S;水泥熟料的矿物形貌未发生明显的变化。

Abstract: Using limestone, anhydrite, fly ash and silica as raw materials, the influence of alkalinity modulus and burning temperature on the formation of clinker minerals were studied under the fixed aluminum /sulfur ratio (P) of 3.82 and alumina content of 10%. The results show that the cement prepared with the alkalinity modulus of 1.2 and the burning temperature of 1375~1425℃ is high-belite Portland cement. C4A3S decomposes into C3A instead of C12A7. The presence of SO3 and C3A improves the formation of C3S at low temperatures and C3S partially decomposes to give α'-C2S. The micromorphology of cement clinker minerals shows no apparent difference.
Key words:  Alkalinity modulus    Burning temperature    Clinker minerals
