摘 要：
为了探讨在混凝土中掺入自燃煤矸石、矿渣对高性能混凝土抗渗性能的影响,采用自燃煤矸石和矿渣作为高性能混凝土的掺合料,通过正交试验确定了最优配合比方案,其最优方案为A1B1C2D3E2。以该最优方案配制高性能混凝土做抗渗试验,其抗渗性能比基准混凝土提高了48%。结合混凝土微观结构分析,得出掺入矿物细掺料后,对混凝土的水化产物有很大的改变,使得混凝土更加密实,改善了混凝土的力学性能和耐久性能。因此,复合掺入自燃煤矸石和矿渣能够制备出工作性好、强度高、抗渗性能良好的高性能混凝土。

摘 要：
In order to study the effect of adding spontaneous combustion gangue and slag on the anti-permeability performance of the high performance concrete,different-proportion spontaneous combustion gangue and slag are used as mixing material,the most optimum mixing ratio scheme,namely A1B1C2D3E2,is selected through the orthogonal experiment.The anti-permeability performance of the concrete,which adopts the optimum mixing ratio scheme,can be enhanced at 48% than basic concrete.Through microcosmic-structure analysis,it is found that after adding mixing material,the hydration products of concrete changed greatly,the concrete became denser,and the mechanics and durability performance of the concrete were enhanced.So high-performance concrete with high intensity and good anti-permeability performance can be produced through adding spontaneous combustion gangue and slag.
