矿渣微粉掺量对混凝土劈裂抗拉性能的影响

Influence of the Slag Powder Dosage Quantity on Splitting Tensile Properties of Concrete

通过在普通硅酸盐混凝土掺入矿渣微粉并对其进行试验研究,分析了龄期、矿渣微粉掺量与水胶比的不同对混凝土劈裂抗拉强度的影响。试验结果表明,矿渣微粉掺量的增加使得混凝土的劈裂抗拉强度先增加后减小,龄期的增长使得混凝土的劈裂抗拉强度增加,水胶比的增加使得混凝土的劈裂抗拉强度减小。

Through the ordinary silicate concrete mixed with slag powder and its experimental research, its impact on the concrete splitting tensile strength was analyzed with different age, slag powder content and the water-binder ratio. The test results show that the increase of slag powder content makes splitting tensile strength of concrete reduce after the first increase; growth age makes splitting tensile strength of concrete increase;increasing water-binder ratio makes the splitting tensile strength of concrete intensity decrease.
