目前,我国仍然处于城镇化进程中,每年会产生大量的建筑垃圾。这些建筑垃圾带来了严重的环境污染问题,如果能对这些建筑垃圾再利用,既能节约自然资源,又能减轻对环境的污染,可以带来可观的经济和社会效益。道路再生混凝土可以很好的解决建筑垃圾的问题,越来越受到人们的重视。但由于再生混凝土原材料的复杂性,其性能指标还没有普通混凝土那样有比较成熟的理论和经验公式。本文通过研究水灰比、再生粗骨料取代率以及砂率等因素对再生混凝土性能的影响,希望对再生混凝土性能有更深入的认识。
At present, our country is still in the process of urbanization, and will generate a large amount of construction waste every year. These construction rubbishes bring about serious environmental pollution problems. If these construction rubbish can be reused, it can not only save natural resources but also reduce the pollution to the environment, which can bring considerable economic and social benefits. Road recycled concrete can be a good solution to the problem of construction waste, more and more people’s attention. However, due to the complexity of raw materials for recycled concrete, its performance index has no more mature theory and empirical formula than ordinary concrete. In this paper, by studying the effect of water-cement ratio, replacement rate of recycled coarse aggregate and sand rate on the properties of recycled concrete, we hope to have a deeper understanding of the properties of recycled concrete.
