本文件规定了通过以下方法确定新拌混凝土稠度的方法: 是时候了。 该试验适用于骨料中最粗部分的声明值为D的试样 实际用于不大于63 mm的混凝土（Dmax）。 如果Vebe时间小于5秒或大于30秒，则混凝土具有Vebe测试所需的稠度 这是不合适的。交叉引用:EN 12350-1购买时可用的所有现行修订版均包含在本文件的购买中。

This document specifies a method for determining the consistence of fresh concrete by means of the Vebe time. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm. If the Vebe time is less than 5 s or more than 30 s, the concrete has a consistence for which the Vebe test is unsuitable.Cross References:EN 12350-1All current amendments available at time of purchase are included with the purchase of this document.
