混凝土材料现已成为全世界各种结构工程建设首选的建筑材料。随着科技的发展和混凝土技术的进步,混凝土外加剂已成为高性能混凝土材料不可缺少的重要组分。通过在混凝土中掺入少量的发泡剂,改善混凝土的内部结构,优化混凝土中集料与水泥浆体的界面状态,提高混凝土性能。文章主要分析了泡沫混凝土的特性、施工工艺以及国外泡沫混凝土应用的新进展。 Concrete materials have now become the preferred building material for various structural engineering projects throughout the world. With the development of science and technology and the progress of concrete technology, concrete admixtures have become an indispensable and important component of high-performance concrete materials. By incorporating a small amount of foaming agent into the concrete, the internal structure of the concrete is improved, the interface state between the aggregate and the cement paste in the concrete is optimized, and the performance of the concrete is improved. This article mainly analyzes the characteristics of foamed concrete, construction technology and new progress in the application of foamed concrete in foreign countries.
