Vegetable coal gangue pervious concrete material and preparation method thereof
The invention discloses a vegetation coal gangue pervious concrete material and a preparation method thereof, and belongs to the technical field of hydraulic materials, the vegetation coal gangue pervious concrete material comprises the following raw materials by mass: 71-71.5% of coal gangue aggregate, 19.4% of cement, 2.5-3.2% of silica fume, 1.3-1.9% of fly ash, 0.4% of a water reducer, 4.3-4.5% of water, and 0.2-1.1% of water-soluble polyurethane. Cement, silica fume, fly ash, a water reducing agent, water and water-soluble polyurethane are doped into coal gangue aggregate, and the coal gangue pervious concrete is formed after stirring, forming and curing. According to the present invention, the gangue is adopted as the aggregate to completely replace natural sand and stone to develop the gangue pervious concrete hydraulic new material, and the gangue pervious concrete hydraulic new material is widely used in the water conservancy project, such that the harmless treatment and the resource utilization of the gangue are achieved, and a series of problems of farmland occupation, river channel occupation, environmental pollution and the like caused by the mass emission of the industrial solid waste gangue are solved.
本发明公开了一种可植生煤矸石透水混凝土材料及其制备方法，属于水工材料技术领域，可植生煤矸石透水混凝土材料包括下述质量百分比的原料：煤矸石骨料71～71.5％，水泥19.4％，硅灰2.5～3.2％，粉煤灰1.3～1.9％，减水剂0.4％，水4.3～4.5％，水溶性聚氨酯0.2～1.1％。将水泥、硅灰、粉煤灰、减水剂、水和水溶性聚氨酯掺入煤矸石骨料中，通过搅拌、成型、养护后形成煤矸石透水混凝土。通过以煤矸石为集料100％替代天然砂、石开发煤矸石透水混凝土水工新材料，广泛用于水利工程中，实现煤矸石无害化处理与资源化利用，解决现有大量排放煤矸石这一工业固体废弃物造成的占用耕地、侵占河道及环境污染等一系列问题。
