The invention provides a coal gangue recycled concrete drain pipe. The coal gangue recycled concrete drain pipe is prepared from the following raw materials in parts by weight: 160 to 170 parts of cement, 300 to 350 parts of coal gangue, 40 to 50 parts of lime, 13 to 23 parts of gypsum, 40 to 45 parts of cementing material, 300 to 400 parts of superfine sand, 500 to 800 parts of gravel, 5 to 10 parts of water reducing agent, 0.35 to 0.55 part of plasticizer, 15 to 28 parts of low-melting-point glass powder, 6 to 15 parts of nanoscale titanium dioxide, 5 to 15 parts of inorganic filler, 22 to 25 parts of composite binder and 100 to 140 parts of water. The cement, the coal gangue, the lime, the gypsum, the superfine sand, the plasticizer and the water are stirred and mixed according to different proportions, the coal gangue mortar meeting different breaking strength, compressive strength and bonding strength can be prepared, and the coal gangue mortar can replace cement mortar and is widely applied to preparation of concrete drainage pipes. Therefore, not only the problems of large occupied area and serious environmental pollution of the coal gangue aresolved, but also the coal gangue is turned into wealth, resources are saved to a great extent, and very high social benefits and economic benefits are achieved.
本发明提供一种煤矸石再生混凝土排水管，原料的重量份配比为：水泥160‑170份，煤矸石300‑350份，石灰40‑50份，石膏13‑23份，胶结料40‑45份，特细砂300‑400份，碎石500‑800份，减水剂5‑10份，塑化剂0.35‑0.55，低熔点玻璃粉15‑28份，纳米级钛白粉6‑15份，无机填料5‑15份，复合粘结剂22‑25份，水100‑140份。按不同比例将水泥、煤矸石、石灰、石膏、特细砂、塑化剂和水搅拌混合，即可制得满足不同抗折强度、抗压强度和粘接强度的煤矸石砂浆，可以取代水泥砂浆，广泛应用于制备混凝土排水管中。这样，不仅解决了煤矸石占地面积大和环境污染严重的问题，而且，煤矸石变废为宝，在很大程度上节省了资源，具有非常高的社会效益和经济效益。
