摘　　要：对于材料吸水性有关的材料的物理性能以及吸水率对墙体材料性能,如孔隙率、干燥收缩和抗冻性等的影响进行了讨论,介绍了美国标准ASTM关于对墙材吸水性的规定,最后建议在砖和砌块墙材标准中应以体积吸水率取代质量吸水率表示墙材的吸水性。The article analyzes the physical performance affecting the water absorption of material and the effect of the water absorption on the performance of wall material, such as porosity, dry shrinkage and frost resistance. Meanwhile, introduces the water absorption in the America standard of ASTM. Finally proposes that the water absorption of wall materials should be indicated by the volume water absorption instead of mass water absorption.
