called Plunge test. This test measures the mass loss of concrete by washout in water [4]. Drop test The basic equipment constitutes graduated cylinder filled with water. A small quantity of concrete (400-500g) is dropped through the water in the cylinder. The resultant turbidity of the water is visually assessed to determine the degree of washout.Concrete Structures, recognized a need for standardized criteria as well as a standardized method of testing reinforced concrete structures for watertight-ness. AWWA's Committee 400, Waterproofing, was also interested in docu-menting the state-of-the-art of watertightness testing and criteria for reinforced concrete tanks.the reservoir. When water issues freely through the drain-cock, it shall be closed and the water reservoir filled. The reservoir water inlet and air bleeder valves shall then be closed. Running the Test 1.With the system completely filled with water, .Equipment; flow table, Abrams cone, water bucket and broom. The cone filled with concrete, prior to lifting. The diameter of the resulting flow is measured. The flow table test or slump-flow test is a method to determine consistency of fresh concrete. Flow table test is also used to identify transportable moisture limit of solid bulk cargoes. [1]
