Preparation and application of coal gangue fine aggregate concrete
The invention provides preparation and application of coal gangue fine aggregate concrete, which is prepared from the following raw materials in parts by weight: 210 parts of cement, 130 parts of fly ash, 180 parts of aggregate, 5 parts of water reducing agent, 220 parts of water and 6 parts of air entraining agent, according to the formula ratio, 6 parts of air entraining agent is added into water, then 130 parts of fly ash is added, the materials are mixed and stirred uniformly, then 210 parts of cement and 180 parts of aggregate are mixed and stirred uniformly, and the coal gangue fine aggregate concrete is prepared. According to the present invention, the prepared coal gangue fine aggregate concrete has characteristics of strong water permeability, strong water permeability in the hardened terrace, alleviation of the difficult problems of mass accumulation and nowhere use of the coal gangue fine aggregate, high porosity, grass planting and afforestation on the spontaneous combustion gangue mountain, and good economic benefits, the environment is beautified.
本发明提供一种煤矸石细骨料混凝土的制备及应用，包括以下重量份的原料：水泥210份、粉煤灰130份、骨料180份、减水剂5份、水220份、引气剂6份，按照配方量，在水中加入引气剂6份，再加入粉煤灰130份混合搅拌均匀，再将水泥210份、骨料180份混合搅拌均匀后，向其中加入减水剂5份，继续搅拌均匀即可，它制备出的煤矸石细骨料混凝土透水性能强，硬化后的地坪中具有较强的透水性，可缓解煤矸石细骨料大量堆积、无处使用的难题，且制备出的混凝土孔隙率较高，在自燃后的矸石山上也可种草造林，美化环境。
