伊通 (YTONG)轻质加气砼砌块是一种新型墙体材料。文章介绍了它的物理力学性能 ,并通过对两种厚度砌块墙体隔声的实验室测试 ,分析了厚度和抹灰对隔声性能的影响。其中抹灰对隔声的影响显著 ,约可使墙体的隔声量提高 5～ 6dB。和常用的轻质砌块墙体的隔声量比较结果表明 ,伊通砌块墙体的隔声量较高 ,厚度2 0 0mm的隔声量接近住宅分户墙一级隔声标准
YTONG light aerated concrete block is a new type of wall material. The paper introduces its physical and mechanical properties. Through the laboratory tests on the sound insulation of two kinds of thick block walls, the influence of thickness and plastering on the sound insulation performance is analyzed. Among them, plastering has a significant impact on sound insulation, which can increase the sound insulation of the wall by about 5 ~ 6dB. And the commonly used lightweight block wall sound insulation volume comparison results show that, Yitong block wall insulation is high, the sound insulation thickness of 200 mm close to the residential wall level a sound insulation standard
