1引言蒸压加气混凝土具有体积密度小、保温隔热、吸声隔音、施工简便等优点,是一种绿色环保的建筑材料,在广东省的建筑节能工程领域中得到广泛应用。目前国家标准GB/T 11969-2008《蒸压加气混凝土性能试验方法》要求试件需在8%~12%的含水状态下进行力学性能试验,但标准中对于如何准确调节含水率并没有具体的
1 Introduction Autoclaved aerated concrete has the advantages of small bulk density, thermal insulation, sound absorption and sound insulation, easy construction and so on. It is a kind of green building material and widely used in the field of building energy conservation in Guangdong Province. The current national standard GB / T 11969-2008 “Autoclaved aerated concrete performance test method” requires the specimen to be in the 8% to 12% aqueous state mechanical properties test, but the standard for how to accurately adjust the moisture content and no specific of
