Coal gangue brick fully utilizing waste resources and preparation method thereof
The invention discloses a coal gangue brick fully utilizing waste resources and a preparation method thereof, and belongs to the technical field of building materials.The preparation method comprises the steps that a mixture is subjected to compression molding and drying in a mold, then the mixture is transferred into a sintering furnace to be subjected to heat preservation for 60-90 min at the temperature of 550-600 DEG C, natural cooling is conducted, a pre-sintered brick blank is obtained, the pre-sintered brick blank is soaked with a reinforcing treating agent till the water content is 10-15%, drying is conducted, and the coal gangue brick is obtained. And then transferring the mixture into a sintering furnace for heat preservation for 45-60 minutes at 250-300 DEG C, for heat preservation for 60-90 minutes at 900-950 DEG C and for heat preservation for 60-90 minutes at 1200-1250 DEG C, and naturally cooling to obtain the coal gangue brick fully utilizing waste resources. Coal gangue waste resources and concrete waste resources are fully utilized, and after the coal gangue waste resources and the concrete waste resources are blended, the prepared coal gangue brick has high compressive strength and water permeability coefficient and is conveniently applied to urban roads.
本发明公开了一种充分利用废弃资源的煤矸石砖及其制备方法，属于建筑材料技术领域，将混合料在模具中压制成型，烘干，然后转移至烧结炉中550‑600℃保温60‑90min，自然冷却，得到预烧结砖坯，将预烧结砖坯用增强处理剂浸湿至含水量为10‑15％，烘干，然后转移至烧结炉中250‑300℃保温45‑60min，900‑950℃保温60‑90min，1200‑1250℃保温60‑90min，自然冷却，得到充分利用废弃资源的煤矸石砖；充分利用煤矸石废弃资源和混凝土废弃资源，对矸石砖对煤矸石废弃资源和混凝土废弃资源进行配料后，制备的煤矸石砖具有较高的抗压强度和透水系数，便于在城市道路中应用。
