Testing of concrete is done to achieve the quality of concrete work. There are different type of test that are done in fresh concrete and harden concrete. Slump test, flow test, temperature checks are usually done in fresh concrete while concrete cub test or concrete cylinder test is mainly done in harden concrete.

The workability-dispersion-cohesion method is a new proposed method for the design of normal concrete mixes. The method uses special coefficients called workability-dispersion and workability-cohesion factors. These coefficients relate workability to mobility and stability of the concrete mix. The coefficients are obtained from special charts depending on mix requirements and aggregate properties.
