矿渣粉掺量影响混凝土泌水与新拌特性研究

摘要

高炉矿渣粉被广泛应用于混凝土中,但矿渣粉的斥水特性,常使混凝土因泌水而造成严重的表面粉化.通过探讨高炉矿渣粉掺量对混凝土泌水特性与新拌混凝土性能的影响,期望根据相关试验结果找出较合理的矿渣粉掺量比例.%Blast furnace slag powder was extensively used into concrete. But the bleeding characteristic of blast furnace slag powder frequently results in serious bleeding and dusting of concrete. The various cement replacements by blast furnace slag powder affect on the bleeding characteristic and fresh properties of concrete.It is expected to find out the optimum cement replacement by blast furnace slag powder according to the related test results.
