建材工业部科教局于去年年底主持召开了《蒸压加气混凝土砌块》部标准审定会议。该标准的主要内容有:①加气混凝土砌块一般规格尺寸为长600毫米;高200、250、300毫米;厚100、150、200、250毫米。②技术性能指标有四项:干容重,立方体抗压强度,标准方法和快速方法测定的干燥收缩值,抗冻性。③外观和尺寸偏差。其中长、高、宽度尺寸允许偏差分别
At the end of last year, the Bureau of Science, Technology and Industry of the Ministry of Building Materials undertook the meeting to hold a standard validation meeting for the Ministry of Autoclaved Aerated Concrete Blocks. The main contents of the standard are as follows: 1 Aerated concrete blocks are generally 600 mm in length, 200, 250, and 300 mm high and 100, 150, 200, and 250 mm thick. 2 There are four technical performance indicators: Dry Bulk Density, Cube Compressive Strength, Standard Method and Dry Method for Determination of Dry Shrinkage, Frost Resistance. 3 appearance and size deviation. In which the length, height and width dimensions allow deviations
