摘要
在全球绿色发展背景下,建筑业作为一个关键领域,正积极寻求更加环保可持续的发展路径。以工业废料循环利用为基础,探索绿色混凝土的制备过程,其中包括高炉矿渣粉、粉煤灰、微硅粉以及钢渣等工业废料的有效利用。设计18种混凝土试件,探讨它们在常温和高温条件下的性能。研究结果表明,利用这些工业废料制备的绿色混凝土在流动性和力学性能上优于普通混凝土,抗压强度平均提升23%至24%。在高温性能方面,绿色混凝土表现出更慢的温度上升速度和优越的隔热性能。具体而言,钢渣和矿渣掺和料在提升混凝土高温性能方面发挥了积极作用,特别是在400℃至800℃范围内。该研究提出的基于工业废料循环利用的绿色混凝土为建筑业的可持续发展提供了有力支持,降低了对自然资源的依赖,减轻了环境负担。
In the context of global green development,the construction industry,as a key field,is actively seeking a more environmentally sustainable development path.Based on the recycling of industrial waste,the preparation process of green concrete was explored,including the effective utilization of industrial waste such as blast furnace slag powder,fly ash,micro-silica powder and steel slag.Eighteen kinds of concrete specimens were studied and designed,and their performance under normal and high temperature conditions was discussed.The results show that the green concrete prepared by using these industrial wastes is superior to ordinary concrete in terms of fluidity and mechanical properties,and the compressive strength is increased by an average of 23%to 24%.In terms of high temperature performance,green concrete exhibits a slower temperature rise rate and superior thermal insulation performance.Specifically,steel slag and slag admixtures play a positive role in improving the high temperature performance of concrete,especially in the range of 400℃to 800℃.The green concrete proposed by the study based on the recycling of industrial waste provides strong support for the sustainable development of the construction industry,reducing the dependence on natural resources and reducing the environmental burden.
