Unbound and hydraulically bound mixtures - Part 45: Test method for the determination of the workability period of hydraulically bound mixtures
未结合和水力结合的混合物 - 第45部分:测定水硬混合物的可加工性期间的试验方法
This European Standard described test methods to determine the workability period of a hydraulically bound mixture using granular materials.
Two methods are described: delayed compaction and sonic propagation. The latter method is not suitable for hydraulically bound mixture with D less than or equal to 6,3 mm.
