The consistency and workability of concrete is a very important factor and is strictly connected to the water/cement ratio, to the effect of admixtures and finally to the strength and quality of concrete. Suitable for concrete mixes of high and very high workability. To perform this test, a sample is placed on a metal surface which is then raised and dropped through a known height.
