利用固体废弃物复合制备绿色矿物掺合料的试验研究

Study on green mineral admixtures prepared by the solid waste

以矿粉为基料,掺加石屑、粉煤灰、炉渣、磷石膏制备了绿色矿物掺合料。测试了绿色矿物掺合料的比表面积、密度、活性指数及制备混凝土的工作性,结果表明:通过掺加石屑、粉煤灰能制备出符合国家标准的复合矿粉,其活性指数高,配制的混凝土工作性能良好。

The slag mixed with stone chips,flyash,blast furnace slag,phosphogypsum prepared green mineral admixtures.Tested specific surface area,density,activity index performance of green mineral admixtures.The results showed that by mixing stone chips,fly ash could be prepared in line with the national standard green mineral admixtures which had high activity index and good working performance.
