Put the concrete into the slump cone, to test the concrete flowing to the time of 50cm (T50) and final divergence(D) after lift the slump cone. Flow time reflects the concrete’s  flowing ability and plastic yielding ability. The general requirements of T50 about 3 to 6s, D value between 650 to 750mm, test the homogeneity, segregation degree, stratification of concrete and the distribution of stones. This method with simple equipment is similar to the way of traditional slump cone set.
