【摘要】 为防止灰水下渗而造成的环境污染,贮灰场必须采取适当的防渗结构和措施,而铺盖防渗是一种适宜的防渗形式。针对不同质量等级的粉煤灰,通过试验确定了HAS固化剂、粉煤灰、减水剂和水的配合比,获得28d龄期抗压强度2.0MPa以上、90d龄期渗透系数不大于10^-6cm/s数量级的铺盖材料。性能测试表明,固化粉煤灰铺盖材料能满足贮灰场防渗要求,价格经济,是一种新型环保防渗材料。更多还原

【Abstract】 In order to prevent environment pollution from leaching water in fly ash field, solidified fly ash are used as waterproof blanket material. The mixture made with fly ash, water reducing agent and water has a compressive strength of not less than 2. 0 MPa in 28 days and a permeability coefficient of not greater than 10 ~6cm/s. The results of analysis made with the engineering properties of solidified fly ash indicate that the solidified fly ash can meet the waterproof property of the fly ash field blanket and is a new environmental protection material.更多还原
