日前,一条以矿山尾砂、废石占原材料85%的新型建材尾矿砼小型空心砌块和高级彩色亮室外地坪砌块生产线,经工商部门批准,在河北承德市寿王坟铜矿建成投产。尾矿砼小型空心砌块是一种墙体材料,一期工程年生产200万块,一块相当于9.6块粘土砖,可供10万立方米建筑物的需要。与砖混建筑相比具有节省能源、施工速度快、减轻墙体自重、保温、隔热、防震等特点。经国家建筑材料测试中心检验,各项性能指标达到国家标准。一期工程年生产3种规格100万块高级彩色光亮室外地坪砌块,可通过模具调整变化生产6种
Recently, a mining tailings, waste accounted for 85% of the raw materials of new building materials tailings concrete small hollow block and high-color bright outdoor floor block production line, approved by the business sector in Chengde City, Hebei Shouwangfen copper built Put into production. Small tailings concrete hollow block is a kind of wall material, a project annual production of 2 million, an equivalent of 9.6 clay brick, for 100,000 cubic meters of building needs. Compared with brick and concrete buildings have energy saving, construction speed, reduce the weight of the wall, insulation, heat insulation, shockproof and so on. Testing by the National Building Materials Testing Center, the performance indicators have reached the national standard. A project in the production of three kinds of specifications 1 million high-quality outdoor bright color floor block, mold changes can be adjusted by the production of 6
