矿渣沸石基水泥的试验研究

研究了矿渣沸石基水泥中原料组成含量对水泥的强度、凝结时间及标准稠度等性能的影响规律,并探讨了该水泥体系的水化机理。研究结果表明,以30%的沸石、25%的熟料、34%的矿渣、6%的钢渣和5%的石膏,可以制备出3d抗压强度达15.3MPa、28 d抗压强度达42.8 MPa的矿渣沸石基水泥。该水泥的主要水化产物为C-S-H凝胶和水化硫铝酸钙。

Experimental study on slag zeolite cement

The effect of material composition of the slag zeolite cement on cement strength, setting time standards of consistency, and the hydration mechanism of the cement was also disussed. A kind of slag zeolite cement has been successfully developed with 30% zeolite,25% clinker,34% slag,6% steel slag and 5% gypsum, the 3 d compressive strength of the cement would be 15.3 MPa and the 28 d compressive strength would be 42.8 MPa. The main hydrate product of the cement is C-S-H and calcium aluminate hydrate.
