Precast concrete products - Test method for glass-fibre reinforced cement - Part 7: Measurement of extremes of dimensional variations due to moisture content
预制混凝土产品 - 玻璃纤维增强水泥的试验方法 - 第7部分:测量由含水量引起的尺寸变化的极限
This European Standard specifies a test method for identifying the maximum dimensional variations (residual hydraulic shrinkage and reversible expansion) of a GRC composition attributable to variations in the water content to which products exposed to the elements may be subjected.
