摘　　要：了解陶粒的吸水性能,尤其是对其进行压力下的吸水性能试验研究,对于优化泵送轻集料混凝土的性能和工艺提供了技术基础。主要研究了内外结构不同的3种陶粒在常温常压下的吸水特性和其在压力作用下的吸水特性,研究在这两种状态下影响陶粒吸水率的主要因素及产生影响的原因。To understand the water absorption properties of ceramsites, especially tests were carried out to study the performance of the water under pressure, provides the technical foundation for the optimization of pumping lightweight aggregate concrete properties and pro-cess.This paper mainly studies the water absorption properties of three kinds of ceramsites with different structures under normal tempera-ture and pressure and the pressure, research on these two kinds of state influence factors of ceramsite water absorption ratio and the reasons of that.
