水化硅酸钙晶体和胶体是加气混凝土的主要水化产物，晶/胶比是影响加气混凝土强度的关键因素。本文通过对高性能砂加气混凝土和粉煤灰加气混凝土的BSE图像进行处理，计算了两种制品中晶体的体积率和胶体的体积率。分析结果表明，在相同的水热合成工艺条件下，高性能砂加气混凝土的晶体与胶体总体积率为粉煤灰加气混凝土的1.4倍，两种加气混凝土的晶体/胶体体积比分别为1.7和1.2。图像分析法提供了评价加气混凝土水化产物的科学依据和方法。

Tobermorite crystal and C-S-H gel are main hydrates of aerated concrete (AC),and Crystal/gel ratio (C/G) is one of the key factors affects strength of AC. Here, the volume C/Gs of AC with high performance sand and fly ash were calculated based on the BSE imaging. It's indicated that the total volume of AC with sand is 1.4 times that of AC with fly ash under the same hydrothermal condition, and C/Gs of the two ACs are 1.7 and 1.2 respectively. BSE imaging provides a scientific basis and method for evaluation hydrates of AC.
