Mortar material prepared from waste rubber and calcined coal gangue solid waste and method thereof
The invention discloses a mortar material prepared from waste rubber and calcined coal gangue solid waste and a method thereof, and belongs to the technical field of preparation of mortar materials from solid waste. The solid waste is obtained by crushing undisturbed coal gangue to 4.75 mm or below and calcining to obtain coal gangue sand which completely replaces river sand to serve as aggregate, the waste rubber particles replace 0-30% of coal gangue sand, 3.8-6% of calcined coal gangue sand/cementing material and 0.8-1.4% of water/cementing material in an isovolumetric manner, and the water reducing agent accounts for 0.8-1.5% of the weight of the cementing material. Mixing and uniformly stirring the cement, the calcined coal gangue sand and the waste rubber particles; the mortar material can be prepared by stirring and dissolving the water reducing agent and water and then mixing the mixed aggregate with the water solution. According to the invention, solid wastes are utilized, a large amount of resources are saved, the environment is protected, the win-win of environmental, social and economic benefits is realized, the advantages of improving the technical performance of the mortar by utilizing the waste rubber aggregate are utilized, the problems of poor fluidity, poor durability and the like of the calcined coal gangue mortar are solved, and the method also has certain practical significance.
一种利用废旧橡胶加煅烧煤矸石固体废弃物制备的砂浆材料及其方法，属于固体废弃物制备砂浆材料技术领域。固体废弃物为原状煤矸石经破碎至4.75mm以下、煅烧后得到煤矸石砂并完全替代河砂做为骨料，废弃橡胶颗粒等体积替换煤矸石砂0~30%，煅烧煤矸石砂/胶凝材料为3.8‑6，水/胶凝材料为0.8‑1.4，减水剂占胶凝材料重量的0.8‑1.5%。将水泥、煅烧煤矸石砂、废旧橡胶颗粒混合后搅拌均匀；将减水剂与水搅拌溶解，再将混合骨料与水溶液混合，就可制得砂浆材料。本发明利用固体废弃物，节约大量资源，保护环境，实现环境、社会和经济效益的共赢，利用废弃橡胶集料改善砂浆技术性能的优势，解决煅烧煤矸石砂浆流动性差，耐久性差等问题，也具有一定的实际意义。
