通过对混凝土力学性能测定,研究了矿渣细度和掺量对混凝土结构的影响。结果表明:在同一掺量下,随着矿渣细度增加,其混凝土的抗压强度增加。当矿渣粉的比表面积为550 m 2/kg,掺量为50%时,其抗压强度到达最高值。矿渣的活性效应和填充效应有效地改善硬化混凝土浆体的微观结构和孔结构,从而使混凝土的力学性能有所提高。矿渣越细,其活化效应和填充效应越好,越有利于提高和改善混凝土的性能,提高混凝土质量。
By measuring the mechanical properties of concrete, the effects of slag fineness and content on concrete structure were studied. The results show that with the increase of slag fineness, the compressive strength of concrete increases at the same dosage. When the specific surface area of the slag powder is 550 m 2 / kg, the compressive strength reaches the highest value when the content is 50%. The activity effect and filling effect of slag effectively improve the microstructure and pore structure of hardened concrete slurry, so that the mechanical properties of concrete are improved. The finer the slag, the better its activation effect and filling effect, the more beneficial to improve and improve the performance of concrete and improve the quality of concrete.
