| 摘 要： | 雅泸高速公路沿线矿区堆积了大量石棉尾矿,为了科学地进行资源再利用,将石棉尾矿作为筑路混凝土粗集料应用于公路建设,需对该种材料进行基本物理力学性能研究。对石棉尾矿进行成分鉴定、毒性检测以及压碎值、含泥量、密度、坚固性、磨光值、磨耗值、碱集料反应等一系列试验。结果表明:石棉尾矿粗集料的相关指标均满足技术要求,可以作为水泥混凝土和沥青混凝土粗集料应用于公路工程建设。

| Abstract: | There is a large amount of asbestos tailing stacked along Ya'an-Lugu Highway.It is necessary to make research on its basic indexes for resources recycle scientifically.The basic indexes of used as coarse aggregate in road concrete such as ingredient identify,toxicity,crushing value,silt content,porosity,compressive strength were studied by experiments in this paper.It's shown that the technical indexes of asbestos tailings all satisfy the required criteria.Asbestos tailings can be used in pavement concrete ... |
