石棉尾矿中除含石棉外,尚含白云质灰岩,颜色洁白,形状是多菱角的多边形,莫氏硬度4～5度,耐风化、耐腐蚀,结合SiO_2含量11～12%,游离SiO_22%。其强度(公斤/厘米~2):抗压1500,抗剪175,抗拉60。化学成分(%):SiO_212,CaO31,MgO20,Al_2O_3+Fe_2O_3 2.3,烧失量34.7。堆放石棉尾矿,既占用大量土地,且污染环境。但石棉尾矿除可回收一些石棉外,尚可用来生产以它为骨料的碳化砖,并可从中回收水磨石和水刷石以及内墙的细砂粉等用的建筑材料。
Asbestos tailings in addition to asbestos, but also with dolomitic limestone, white color, the shape is more water chestnut polygons, Mohs hardness of 4 to 5 degrees, resistance to weathering, corrosion resistance, combined with SiO_2 content of 11 to 12%, free SiO_22 %. Its strength (kg / cm ~ 2): compression 1500, shear 175, tensile 60. Chemical composition (%): SiO_212, CaO31, MgO20, Al_2O_3 + Fe_2O_3 2.3, loss on ignition 34.7. Stacked asbestos tailings, both take up a lot of land, and pollute the environment. However, asbestos tailings can be recycled for some asbestos, but can be used for the production of carbonized bricks based on it and for the recovery of building materials such as terrazzo, water brush and fine sand powder from the interior walls.
