当际看到稀的混凝土时,你会脱口而出:这个混凝土坍落度大;而当你见到较干稠的混凝土时,你又马上会说:这个混凝土的坍落度小。但是怎样测定混凝土坍落度的数值呢?就得有个统一的标准,这个标准是:将混凝土拌合物分三层装入坍落度筒内,每层装入的高度应稍大1/3筒高,每装完一层后,用符合规定的捣 When you see thin concrete, you will blurt out: The slump of the concrete is large; and when you see thicker concrete, you immediately say: The slump of the concrete is small. But how to determine the concrete slump value? There must be a unified standard. This standard is: The concrete mix is ​​loaded into the slump cylinder in three layers, and the height of each layer should be slightly higher 1/ 3 cylinder height, after each layer is installed, meet the requirements
