FLOW TABLE
Introduction of flow table:
The flow table test or flow test is a technique to decide consistency of new concrete. Flow table test is additionally used to distinguish transportable dampness breaking point of strong mass cargoes.It is utilized basically to assess solid that is excessively liquid (workable) to be estimated utilizing the droop test, in light of the fact that the solid won't hold its shape when the cone is evacuated.
Application When crisp cement is conveyed to a site by a truck blender, its consistency should be checked before it is filled formwork.
In the event that consistency isn't at the coveted level, solid won't have the required quality and different characteristics once it has set. On the off chance that solid is excessively pale, cavities may shape inside it. Rebar may end up consumed, and solid will split. Cavities additionally decrease the solid quality.
Conducting the test:
The stream table is wetted.
The cone is set in the focal point of the stream table and loaded with new cement in two equivalent layers. Each layer is packed 10 times with a packing bar.
Hold up 30 seconds before lifting the cone.
The cone is lifted, enabling the solid to stream.
The stream table is then lifted up 40mm and afterward dropped 15 times, making the solid stream.
After this, the breadth of a stream of the solid is estimated.
Specifications:
The flow table consists of a 30 cm dia. polish smooth steel plate with 3 carved annular circles 7, 11 and 19cm Dia. The table top is arranged for a free fall of
12.5mm by a cam action. Supplied complete with one brass conical mold, 65mm i.d. at base and 40mm i.d. at the top, height of the mold 90mm.
Safety and Precautions:
Utilize hand gloves, shoes at the season of test.
Keep the shape and stream table perfect, dry and free from staying concrete.
Keep the vertical shaft greased up with light oil.
Keep the contact countenances of the stream table best and supporting casing oiled.
Keep the hand wheel, the flexible shaft and widespread joint.
