矿物掺合料对陶瓷粗骨料混凝土性能的影响

Effects of Mineral Admixtures on Properties of Ceramic Coarse Aggregate Concrete

试验研究了不同掺量的粉煤灰和硅粉对陶瓷粗骨料混凝土性能的影响。结果表明:随着粉煤灰掺量的增加,陶瓷粗骨料混凝土的抗压强度逐渐降低,但其劈裂抗拉强度逐渐增大,抗水渗透性能提高。复掺硅粉后,陶瓷粗骨料混凝土的抗压强度、抗水渗透能力及炻质粗骨料混凝土的抗拉强度均显著提高,而瓷质粗骨料混凝土的抗拉强度提高幅度较小。

The effects of different contents of fly ash and silica fume on properties of ceramic coarse aggregate concrete were studied. The results show that the compressive strength of ceramic coarse aggregate concrete decreases gradually with the increase of fly ash content, but the splitting tensile strength increases gradually and the performance of resistance to water penetration improves. Mixed with silica fume, the compressive strength and resistance to water permeability of ceramic coarse aggregate concrete, also the tensile strength of semi-porcelain coarse aggregate concrete increase significantly. But the tensile strength of porcelain coarse aggregate concrete increases little.
