实验研究的结果进行了描述，记录和量化的影响，混凝土孔隙率在饱和和干燥状态下的机械性能。混凝土孔隙分为毛细孔隙和夹带孔隙，根据其对混凝土力学性能的影响，将其分为活性孔隙和非活性孔隙。结果发现，活性（毛细管）孔隙率对机械性能的影响是更明显的减少水分。非活性孔隙率对混凝土力学性能的影响不受含水状态的影响。
The findings of an experimental study are described, documenting and quantifying the influence of concrete porosity on its mechanical properties in saturated and dry states. Concrete porosity consists of capillary and entrained air, and described respectively as active and non-active, depending on its influence on mechanical properties with changing moisture state. It was found that the active (capillary) porosity influence on mechanical properties is more pronounced with decreasing moisture. The influence of non-active (entrained-air) porosity on concrete mechanical properties is invariant of moisture state.
