Flow table test
The Flow test is a method to determine the consistence of fresh concrete.
Additional recommended knowledge
When fresh concrete is delivered to a site by a truck mixer it is somtimes necessary to check its consistence before pouring it into the formwork.
If the consistence is not all right, the concrete won't have the desired quality - in particular not the desired stregth.
During the conduction the site engineer should be around.
If the concrete is too pasty this might result in cavities inside the hard concrete which leads to corrosion of the rebar, which again leads cracks which will accelerate the whole process - just like few concrete cover. Cavities will also lower the stress the concrete part is able to support.
