《砼小型空心砌块》国家标准审议会最近在成都召开。与会代表一致认为该标准一等品指标达到了国外先进标准的水平,建议作为国家标准报送国家建材局审批后,在全国发布执行。该标准按砌块的四项技术性能划分等级, 即是:标号(抗压强度),相对含水率,抗渗性允许的尺寸偏差和外观缺陷。该标准有充分的科学根据,内容全面,有利于产品质量的提高。该标准所列各项指标既接近先进国家标准,又符合我国实际水平。
The National Standards Review Conference of “Small Hollow Blocks” was recently held in Chengdu. The delegates agreed that the standard first-class product indicators have reached the level of foreign advanced standards, and they are recommended to be implemented in the country after being submitted to the National Building Materials Bureau as a national standard for approval. The standard is graded according to the four technical performances of the block, ie, the label (compressive strength), relative moisture content, allowable dimensional deviation of impermeability, and appearance defects. The standard has full scientific basis, comprehensive content, and is conducive to the improvement of product quality. The indicators listed in the standard are not only close to the advanced national standards, but also meet the actual level of our country.
