液态渣组成结构与活性研究

A study on composition constitution and activity of liquid slag

本文应用现代测试技术,对液态渣进行分析研究,试图查明液态渣玻璃体的组成结构。为了探索液态渣的结构与水硬活性之间的关系,采用了两种方法来评定液态渣的活性:一是测定液态渣的抗压强度;二是测定液态渣在酸碱介质中的溶出度来考查其化学稳定性。研究结果表明:液态渣尤其是增钙液态渣具有较高的活性,是一种极易利用、用途广泛的“废渣”型活性材料,对解决粉煤灰资源综合利用,实现“无废渣燃煤热电厂”具有重要意义。

The paper describes a study on liquid slag using modern techniques for determining composition structure of glass parts in slag. In order to determine the relationship between composition structure and activity of liquid slag, following methods ard used: 1. Detecting the compressive strength of the slag; 2. Measuring the chemical stability of the slag by resolution degree in acid media. The study shows that the liquid slag, specially the adding-calcium slag, possesses comparatively high activity, is an easily and widely applicable raw material with activity. This study is significant for use of fly ash and for realization of 'coal-fired power station without waste slag'.
