Preparation method of coal gangue thermal insulation concrete
The invention discloses a preparation method of coal gangue thermal insulation concrete. The preparation method comprises the following steps: taking coal gangue, crushing and screening; taking the glass beads and the coal gangue fine particles, continuously crushing, and screening; taking fly ash and coal gangue powder, and performing ball milling to obtain fine particles with the particle size of 0.1-0.2 mm; crushing the obtained coal gangue coarse aggregate again to obtain a continuous particle size material with the particle size of 15-65 mm, washing with water, and drying for later use; and uniformly mixing the fine aggregate of the glass beads and the coal gangue particles, the coarse aggregate of the coal gangue, Portland cement, the fine particles of the fly ash and the coal gangue powder, the additive and the water according to the weight ratio to obtain the thermal insulation coal gangue concrete. The solid waste coal gangue is turned into treasure, the coal gangue, the Portland cement and other materials are prepared into the concrete, the concrete has the characteristic of thermal insulation without losing the strength, durability, mechanical property and the like of the concrete, and the concrete has the advantages of low cost, simple preparation process, good comprehensive performance and the like.
本发明公开了一种煤矸石保温混凝土的制备方法，包括以下步骤：取煤矸石，粉碎后进行筛分；取玻化微珠、煤矸石细颗粒，继续粉碎后进行筛分；取粉煤灰、煤矸石粉进行球磨，得到粒径为0.1～0.2mm的微细颗粒；将得到的煤矸石粗骨料再次破碎得到粒径为15～65mm的连续粒径物料，进行水洗、干燥后备用；按照重量配比分别取所述玻化微珠和煤矸石颗粒的细骨料、煤矸石粗骨料、硅酸盐水泥、粉煤灰与煤矸石粉的微细颗粒、外加剂和水，混匀后即得到保温煤矸石混凝土。本发明将固体废料煤矸石转废为宝，将煤矸石与硅酸盐水泥等材料制备成混凝土，在不损耗混凝土的强度、耐久性、力学性能等还具有保温的特点，具有成本低、制备工艺简单、综合性能好等优点。
