【摘要】：本文以化學(xué)發(fā)泡方法制備了堿礦渣加氣混凝土(AASAC),研究了其孔結(jié)構(gòu)與宏觀性能之間的關(guān)系。結(jié)果顯示:AASAC干密度范圍在400~700 kg/m~3,其體積吸水率與孔隙率成線性相關(guān)性,28 d抗壓強度和干燥收縮值隨孔隙率增加而減小。加氣混凝土斷面圖像分析結(jié)果表明,引入氣孔圓度值接近于1以及氣孔孔徑在100μm以內(nèi)的氣孔比例越大,混凝土強度越高。
[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，
