Description

technical field [0001] The invention relates to the field of new building materials, in particular to a microbial coal gangue / coal slime building material and a manufacturing method thereof. Background technique [0002] Coal gangue and coal slime are solid wastes produced during coal mining and coal washing. Coal gangue and coal slime have become the industrial waste with the largest stockpile and annual output and occupying the most storage space, which has brought a series of problems to the environment and society. The stockpiling of coal gangue occupies a large amount of land, resulting in the reduction of cultivated land and forest land; the spontaneous combustion of coal gangue produces SO 2 , NO x Toxic and harmful gases, toxic and harmful elements will also pollute groundwater and soil with rainwater leaching and infiltration, causing serious harm to the ecological environment; coal companies also need to invest a lot of money every year to solve the problem of co...
