建筑垃圾作为替代性成土材料的效应研究

Research on the effect of construction waste as alternative soil material

建筑垃圾随意填埋处置危害巨大,资源化处理率极低,形势严峻,开展相关综合利用研究刻不容缓。现有的应用与研究多在建筑行业,鲜有从理化特性、生物活性等方面开展研究与应用。本文以建筑垃圾中的粘土砖为主要研究对象,主要通过盆栽试验和室内检测实验,分析建筑垃圾中粘土砖在不同粒径形态下与土以不同比例复配后的保水保肥特性,得出其作为替代性成土材料的制备优化方案,探索其在土地工程建设及土体有机重构中的应用价值与前景,寻求建筑垃圾资源化利用的新途径。

The random landfill disposal of construction waste has great harm,and the recycling rate is very low.So it is urgent to conduct comprehensive exploration research.The existing application and research are mostly in the construction industry,and few from the physical and chemical properties,biological activities and other aspects.Taking clay brick of construction waste as the main research object,this article analyses the water-retaining and fertilizer-keeping property after being compounded with the soil in different proportions in different grain size forms through pot experiment and indoor test,which aims to find an optimized schemes of clay brick as alternative soil material,explore application value and prospect of construction waste in the land engineering construction and soil organic reconstruction,seek new ways of construction waste resource utilization.
