煤矸石混凝土材料耐久性研究进展

Research Progress on Durability of Coal Gangue Concrete Materials

煤矸石是我国重要的工业固体废弃物之一,将其作为集料替代天然集料掺入到混凝土中,既能促进固体废物利用,也能为减少环境污染提供新方向,同时也是目前煤矸石资源利用方式中最经济、环保的一种。本文对其在水泥砂浆中的配制技术进行了介绍,归纳总结了煤矸石掺入到混凝土中后对其耐久性能的作用效果,最后基于煤矸石混凝土的研究现状对煤矸石混凝土进行了进一步展望。

Coal gangue is one of the important industrial solid waste in China.The addition of coal gangue into concrete as an aggregate instead of natural aggregate can not only promote the utilization of solid waste,but also provide a new direction for reducing environmental pollution.At the same time,it is also the most economical and environmentally friendly way of utilizing coal gangue resources.This article introduces the preparation technology of coal gangue in cement mortar,summarizes the effect of coal gangue added to concrete on its durability,and finally provides further prospects for coal gangue concrete based on the research status of coal gangue concrete.
