摘要/Abstract

摘要： 以Texaco气化炉渣、石灰石、粘土和铁粉为原料制备硅酸盐水泥熟料,分别采用X射线衍射仪、金相显微镜对该熟料的物相以及岩相结构进行分析,掺加适量石膏后,依据国标检测水泥的标准稠度用水量、安定性、凝结时间以及龄期强度,推断出制备水泥的标号.结果表明:(1)制备的水泥熟料主要矿相为硅酸三钙、硅酸二钙、铝酸三钙、铁酸钙.(2)当粘土加入量为5%,烧成温度为1450℃时,烧制的水泥28 d抗折强度、抗压强度分别为8.0 MPa、50.9 MPa,可推断其标号为42.5水泥.

Abstract: Silicate cement clinker was prepared using gasification slag from Texaco gasifier , limestone, clay and iron powder as raw materials .The phase composition morphology and microstructure of the clinker were investigated by X-ray powder diffractometry and metallurgical microscope .Adding proper gypsum into the cement clinker , of which the water requirement of normal consistency , stability , setting time and cement grade were measured according to the Chinese standard .The results show that (1) The main compositions of the cement clinker are C 3 S, C2 S, C3 A and C4 AF, which conforms to the chemical composition of cement clinker;(2) The cement 28 d compressive strength and flexural strength is 8.0 MPa, 50.9 MPa, respectively, prepared with 5% clay at 1450 ℃, and it is inferred to be with the labeled 42 .5 .

Key words: Texaco gasification slag;mineral phase;cement clinker;strength
