建筑垃圾再生混凝土抗压性能研究

Research on Compressive Properties of Recycled Concrete for Construction Waste

随着工业化、城市化进程的发展,建筑业也同时加速速发展,随之而产生的建筑垃圾日益增多,成了一个比较严重的环境污染问题。建筑垃圾再生骨料是一种可循环利用的资源,再生骨料混凝土的研究与运用已经引起了建筑行业的广泛关注。本文选择平常生活中的建筑垃圾为骨料,通过对再生混凝土的配合比设计,建筑垃圾再生混凝土的力学性质等一系列实验,主要研究建筑垃圾粗骨料掺量、水灰比、外加剂等因素对建筑垃圾再生混凝土抗压强度的影响,目的在于探讨建筑垃圾代替混凝土粗骨料配置中等强度混凝土的可行性,为绿色建筑材料研发做贡献。

With the development of industrialization and urbanization, the construction industry has also acceleratedthe development, and the construction waste is increasing, which has become a serious environmental pollution prob-lem. Construction waste recycled aggregate is a kind of renewable resource, and the research and application of recy-cled aggregate concrete have attracted wide attention in the construction industry. In this paper, we choose the con-struction waste in our daily life as aggregate, though the design on the ratio of recycled concrete and a series of experi-ments on the mechanical properties of recycled concrete for construction waste, the influences of construction wasteaggregate doping amount, water cement ratio, admixture and other factors on the compressive strength of recycled con-crete for construction waste are mainly researched, to discuss the probability of taking place of concrete coarse aggre-gate distribution medium strength concrete with construction waste, and make contribution to the research and devel-opment of green building materials.
