Flow test

ASTM C109/C109M:
This test method is intended for use with grout having an efflux time of 35 s or less.
When efflux time exceeds 35 s, flowability is better determined by flow table, found in Test Method ASTM C109/C109M, using 5 drops in 3 s.
This test method covers a procedure, used both in the laboratory and in the field, for determining the time of efflux of a specified volume of fluid hydraulic cement grout through a standardized flow cone and used for preplaced-aggregate (PA) concrete; however, the test method may also be used for other fluid grouts.
It is for use with neat grout and with grouts containing fine aggregate all passing a 2.36-mm (No. 8) sieve.
Let see the testing video: The Gilson Grout Flow Cones measure the flow-ability of a 1.725L sample of hydraulic grout used in preplaced aggregate concrete, through a standardized flow cone with a 0.5in (12.7mm) discharge tube in accordance with ASTM C939 (HM-372 model only).

The test is appropriate for concrete of high and very high workability, including flowing concrete which would exhibit a collapse slump. The apparatus consists essentially of a wooden board covered by a steel plate with a total mass of 16 kg. This board is hinged along one side to a base board, each board being 700 mm square. The upper board can be lifted up to a stop so that the free edge rises 40 mm. Appropriate markings indicate the location of the concrete to be deposited on the table. The table top is moistened and a frustum of a cone of concrete, lightly tamped by a wooden tamper in a prescribed manner, is placed using a mould 200 mm high with a bottom diameter of 200 mm and a top diameter of 130 mm. Excess concrete is removed, the surrounding table top is cleaned and, after an interval of 30 seconds, the table top is lifted 15 times in a period of 45 to 75 seconds, this motion avoiding a significant force against the stop. In consequence, the concrete spreads and the maximum spread parallel to the two edges of the table is measured. The average of these two values, given to the nearest millimetre, represents the flow. The test is appropriate for mixes having a flow of 340 to 600 mm. If the concrete at this stage does not appear uniform and cohesive, this is an indication of a lack of cohesiveness of the mix. The current standard is BS EN 12350-5 : 2010.

J-Ring Test set is used for determining the passing ability, the slump flow and the flow time at 500 mm flow spread of self-compacting concrete as the concrete flows through the J-ring apparatus. Standards: EN 12350-8, EN 12350-12, ASTM C1611, C1621:

ASTM C1437, C230, EN 459-2, 1015-3, ASTM C827 / C827M - 16, is the specs for the flow table for hydraulic cement mortars. This will helps in finding out the TML (Transportable moisture limit ) of bulk cargo:
