摘要/Abstract

摘要： 随着钢铁行业矿石品位的下降和生产工艺的调整,矿渣的成分和结构发生变化,导致矿渣胶凝活性下降,难以在水泥基材料中应用。本文从矿渣的成分和结构出发,分析了矿渣水化活性的潜在影响因素,综述了传统的矿渣活化方法及其存在的问题,阐述了醇胺络合活化方法的作用机制及优缺点,并介绍了一种基于络合与碳酸化协同的新型矿渣活化方法,有助于提高矿渣的资源化利用率。

Abstract: With the decline in ore grade and the adjustment of production processes within the steel industry, the composition and structure of slag changes, resulting in the decrease of cementitious activity of slag and rendering its utilization in cement-based materials. Based on the composition and structure of slag, this paper analyzes the potential factors influencing the hydration activity of slag. It reviews traditional slag activation methods and their corresponding issues, elucidates the mechanism of action, advantages, and disadvantages of alkanolamine complexation activation method, and introduces a novel slag activation approach based on the synergistic effect of complexation and carbonation, which aims to enhance the resource utilization rate of slag.

Key words: slag, hydration, reaction activity, traditional activation, complexation activation, coordination complexation and carbonation
