Coal gangue solid waste material serving as raw material admixture
The invention discloses a coal gangue solid waste serving as a raw material admixture. The coal gangue solid waste comprises 85-95% of limestone, 2-10% of coal gangue, 3-9% of sandstone and 2-5% of nonferrous metal ash; in the coal gangue, the content of SiO2 is 52-65%, the content of Al2O3 is 16-36%, the content of Fe2O3 is 2-15%, the content of CaO is 0.25-2.5%, the content of MgO is 0.2-2.5%, the content of TiO2 is 0.5-4%, the content of P2O5 is 0.005-0.25%, the content of K2O is 0.5-2%, the content of Na2O is 0.5-2%, and the content of V2O5 is 0.01-0.1%; the limestone contains 10-30% of SiO2, 5-15% of Al2O3, 5-10% of Fe2O3 and 46-53% of CaO; the sandstone contains 65-80% of SiO2, 7-12% of Al2O3, 1.0-3.0% of Fe2O3 and 1-5% of CaO; and the non-ferrous metal ash contains 20-30% of SiO2, 9-20% of Al2O3, 4-6% of Fe2O3 and 50-55% of CaO. The coal gangue solid waste has the following advantages: the coal gangue is used for replacing clay minerals required in cement production, so that thewaste of resources is reduced, and meanwhile, the pollution of the coal gangue to the environment is reduced.
本发明公开了一种煤矸石固废料作生料掺合料，包括：石灰石、煤矸石、砂岩和有色金属灰渣，其中石灰石：85％～95％、煤矸石：2％～10％、砂岩：3％～9％、有色金属灰渣：2％～5％，所述煤矸石中SiO为52％～65％；AlO为16％～36％；FeO为2％～15％；CaO为0.25％～2.5％；MgO为0.2％～2.5％；TiO为0.5％～4％；PO为0.005％～0.25％；KO为0.5％～2％；NaO为0.5％～2％；VO为0.01％～0.1％，所述石灰石中包含有SiO2：10％～30％，AlO：5％～15％，FeO：5％～10％，CaO：46％～53％，所述砂岩中包含有SiO：65％～80％，AlO：7％～12％，FeO：1.0％～3.0％，CaO：1％～5％，所述有色金属灰渣中包含有SiO：20％～30％，AlO：9％～20％，FeO：4％～6％，CaO：50％～55％，本发明具备使用煤矸石代替水泥生产中所需的粘土矿物，从而减少资源的浪费，同时的减少煤矸石对环境的污染优点。
