根据正交设计法,利用L24(61×41×23)正交表安排试验,探讨了混合材掺量、矿渣微粉与粉煤灰的比例、矿渣微粉细度、粉煤灰品种对水泥胶砂流动度、7,28,90 d龄期的抗压强度的影响,初步确定水泥熟料、矿渣微粉、粉煤灰三元体系的较优组合。结果表明,粉煤灰与矿渣微粉双掺比单掺矿渣微粉或单掺粉煤灰的水泥胶砂,具有一定的优势。

Based on orthogonal design method,the orthogonal list L24(61×41×23) was selected for arranging test,the influences of the quantity of pozzolanic admixture,the ratio of powdered slag and flyash,the fineness of powdered slag,and the quality of flyash on the flowabilities,the compressive and flexural strengths of cement mortar at ages of 7,28,90 and 180 days,respectively,were explored.On the basis of experimental tests,the optimum combination of cement,powdered slag and flyash was determined. The test results showed that the cement mortar containg powdered slag and flyash is better than that only mixing with either powdered slag or flyash.
