摘　　要：浮石是一种分布较为广泛的天然非金属矿藏,其具有非常发达的孔隙结构特征,利用其这一特征可以作为天然轻骨料配制浮石轻骨料混凝土。随着工程建设的飞速发展,普通混凝土自重大、隔热保温性差等问题制约其在某些特定工程上的发展,而浮石混凝土与之相比具有比强度高、保温隔热、抗震耐久等优点。本文概括了浮石的形成过程、特性与研究现状,针对浮石混凝土做了进一步分类,概述各类型浮石混凝土的特点与优势,并阐述了国内外浮石混凝土物理力学性能与耐久性的研究现状,最后对浮石混凝土研究与应用进行展望。Pumice is a widely distributed natural non-metallic minerals,which has a highly developed pore structure characteristic,it could be mixed as a natural lightweight aggregate of pumice concrete with this characteristic. With the rapid development of engineering construction,the problems of ordinary concrete such as larger weight, poor thermal insulation restrict its development in some specific engineering. However compared with ordinary concrete,pumice concrete has the advantages of high specific strength,good thermal insulation,great seismic and durability. This paper summarized the formation process, characteristics and research status of pumice. It further classified the pumice concrete,generalized the characteristics and advantages of the various types of pumice concrete,and described the research situation of pumice concrete in physical mechanical properties and durability aspects. In the end,it prospects the research and application of pumice concrete in the future.
