针对不同种类、不同掺量矿物掺合料的高性能抗冲磨混凝土开展试验研究,探讨矿物掺合料对混凝土抗冲磨性能的影响规律,分析矿物掺合料改善混凝土抗冲磨性能的机理.结果表明:掺入矿物掺合料后,混凝土的抗压强度、抗冲磨强度均有显著地提高,脆性系数有一定程度的降低;混凝土抗压强度提升高达7%,脆性系数降低了约5%;抗冲磨强度提高了12%~19%.研究成果可为抗冲磨混凝土配合比设计及工程应用提供参考.
Study on the Influence of Mineral Admixtures on the Properties of Hydraulic High-Performance Abrasion-Resistant Concrete
Experimental study is carried out on high-performance abrasion resistant concrete with different types and different amounts of mineral admixtures to explore the influence of mineral admixtures on the erosion-resistant performance of the concrete and analyze how mineral admixtures improve the abrasion resistant performance mechanism of the concrete.The results show that after adding mineral ad-mixtures,the compressive strength and abrasion resistance of concrete are significantly improved,and the brittleness coefficient is reduced to a certain extent;the compressive strength of concrete is increased by up to 7%,and the brittleness coefficient is reduced by 5%;the impact resistance is increased by 12%to 19%.The study results can provide reference for the mix design and engineering application of abrasion resistant concrete.
