The invention belongs to the technical field of preparation of composite admixtures, and provides a composite admixture which is prepared by the following steps: S1, preparing an undisturbed fly ash material, industrial slag and limestone beneficiation waste residues; s2, mixing the fly ash undisturbed material and the industrial slag through a metering scale by utilizing an existing cement grinding mill system, and finely grinding through a cement grinding mill to enable the specific surface area of the material in the mill to reach an extremely fine state; s3, after being prepared, the product enters a finished product storage warehouse through conveying equipment for use or sale and shipping; the performance of the concrete prepared by using the cement of the composite admixture is far better than that of the concrete using the secondary fly ash, various performance indexes such as standard consistency, flowing property, setting time and flexural and compressive strength are obviously better than that of the concrete using the secondary fly ash, and the production cost is greatly reduced.
本发明属于复合掺合料制备技术领域，提供了一种复合掺合料，包括如下制备步骤：S1、准备粉煤灰原状料、工业矿渣和石灰石选矿废渣；S2、利用现有水泥磨系统通过计量称掺入粉煤灰原状料和工业矿渣，通过水泥磨精细研磨使物料在磨内比表面积达到极细状态；S3、产品经制备后通过输送设备进入成品储备库，待使用或销售发运；本发明通过使用复合掺合料的水泥制备出的混凝土性能远优于使用二级粉煤灰的混凝土，各项性能指标如标准稠度、流动性能、凝结时间、抗折抗压强度都明显超出使用二级粉煤灰的混凝土，并且生产成本大大降低。
