The J-Ring Test is used for determining the passing ability of self-consolidation concrete. Except for the J ring, the apparatus can be used for performing the slump-flow test.
The TC-0520A, J-Ring with Smooth Roads, is manufactured from stainless steel.
The TC-0524 Base Plate is 920 x 920 x 3 mm square, made of stainless steel with engraved circles of 210 mm and 500 mm diameter conforming to EN and ASTM.
The J-Ring Test is used for determining the passing ability, the flow spread and the t500J flow time of self compacting concrete as the concrete flows through the J-Ring Apparatus.
The TC-0520E J-Ring Narrow Gap with Ø18 mm x 16 smooth bars is manufactured from stainless steel.
The TC-0522E Slump Cone is made from sheet steel protected against corrosion, with diameters; top 100 mm, base 200 mm and with a height of 300 mm.
The TC-0524 Base Plate is made of stainless steel with en¬graved circles of 210 mm and 500 mm diameter conforming to EN 12350-8.
The TC-0526E Steel weighted collar is used to stabilize the slump cone on J-Ring or slump flow tests.
Minimum apparatus for the J-Ring Test are the J-Ring with narrow gap (TC-0520E) and slump cone (TC-0522E)
