【摘要】：本文以化学发泡方法制备了碱矿渣加气混凝土(AASAC),研究了其孔结构与宏观性能之间的关系。结果显示:AASAC干密度范围在400~700 kg/m~3,其体积吸水率与孔隙率成线性相关性,28 d抗压强度和干燥收缩值随孔隙率增加而减小。加气混凝土断面图像分析结果表明,引入气孔圆度值接近于1以及气孔孔径在100μm以内的气孔比例越大,混凝土强度越高。
[Abstract]:In this paper, alkali slag aerated concrete (AASAC), was prepared by chemical foaming method. The relationship between pore structure and macroscopic properties of alkali slag aerated concrete was studied. The results show that the volume water absorption and porosity of AASAC are linearly correlated with the porosity in the dry density range of 400 鈮，
