钢渣掺合料对水泥基材料渗流结构的影响

Influence of Steel Slag on the Percolation Structure of Cement-based Material

对不同掺量的钢渣掺入水泥浆体后引起的渗流结构变化进行了研究,并与掺入矿渣或粉煤灰的水泥浆体渗流结构进行了比较.结果表明:钢渣的掺入有助于提高水泥浆体的水化速率和密实度;与掺矿渣或粉煤灰的水泥基材料相比,当钢渣掺量为30%(质量分数)时,掺钢渣水泥基材料有着更高的密实度和更好的后期性能.

Influence of steel slag on the percolation structure of cement paste was studied. It is showed that the total porosity of cement paste with steel slag is smaller than that of the control specimens and the specimens with blast furnace slag or fly ash. At the same time, the late properties (about 28 d to 180 d) of cement-based material with 30% steel slag mass addition are better than that of cement-based material with blast furnace slag or fly ash.
