Cement-based composite cementing material containing waste clay brick powder and limestone powder
The invention provides a cement-based composite cementing material containing waste clay brick powder and limestone powder. The cement-based composite cementing material is characterized by being prepared from the following raw materials in parts by weight: 5 to 30 parts of waste clay brick powder, 5 to 30 parts of limestone powder, 52 to 81 parts of cement clinker, 2.8 to 4.0 parts of desulfurized gypsum and 0.02 to 0.1 part of water reducing agent. The cement-based composite cementing material is prepared by using the waste clay bricks and the limestone powder as raw materials; the preparation cost of the cementing material is reduced, the resource is saved, the harm of the waste on the environment is reduced, the hydration heat release and the volume shrinkage can be effectively reduced, and the volume stability of the concrete or the mortar can be improved.
本发明提供了一种含有废弃粘土砖粉和石灰石粉的水泥基复合胶凝材料，其特征在于该水泥基复合胶凝材料由如下重量份的原料组成：废弃粘土砖粉5～30份、石灰石粉5～30份、水泥熟料52～81份、脱硫石膏2.8～4.0份和减水剂0.02～0.1份。本发明利用废弃粘土砖与石灰石粉作为原料制备水泥基复合胶凝材料，不仅降低了胶凝材料的制备成本，在节约资源的同时减少了废弃物对环境的危害，此外，所制备的胶凝材料能够有效降低水化放热量和减少体积收缩，提高混凝土或砂浆的体积稳定性。
