Electric furnace steel slag-based cement admixture or concrete admixture as well as preparation method and application thereof
The invention discloses an electric furnace steel slag-based cement admixture or concrete admixture comprising the following components in parts by mass: 80-93 parts of ladle furnace refined steel slag, 2-8 parts of phosphogypsum, 5-12 parts of lithium slag and 0-0.2 part of an additive. The invention further provides a preparation method of the electric furnace steel slag-based cement admixture or concrete admixture and an application of the electric furnace steel slag-based cement admixture or concrete admixture in production and preparation of cement and concrete. The electric furnace reduction steel slag is utilized to the maximum extent, byproducts such as phosphogypsum and lithium slag are combined to serve as auxiliary components, the characteristics of self-hydration hardening andhigh adaptability are achieved, the superposition effect and synergistic efficient utilization of multiple kinds of waste are achieved, waste utilization is achieved, environmental protection is achieved, the cost is low, the cost performance is high, and the application prospect is wide.
本发明公开了一种电炉钢渣基水泥混合材或混凝土掺和料，其包括以下质量份数的组分：钢包炉精炼钢渣80‑93份，磷石膏2‑8份，锂渣5‑12份，外加剂0‑0.2份。本发明还提供了所述的电炉钢渣基水泥混合材/混凝土掺和料的制备方法以及其在水泥与混凝土生产制备中的应用。本发明最大程度地利用了电炉还原钢渣，并结合磷石膏、锂渣等副产品作为辅助组分，使其具有自水化硬化和适应性强的特性，实现了多种废弃物的叠加效应和协同高效利用，利废环保，成本低、性价比高，应用前景广阔。
