J – Ring Test

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-0520 J-Ring Narrow Gap with Ø18mm x 16 smooth bars is manufactured from stainless steel.
The TC-0522 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 900 x 900 x 3 mm square, made of
stainless steel with engraved circles of 200 mm and 500 mm
diameter conforming to EN 12350-8.
The TC-0526 Steel weighted collar is used to stabilise the slump cone on J-Ring or slump flow tests.
Minimum apparatus for the J-Ring Test are J-Ring with narrow
gap ( TC-0520) and slump cone (TC-0522).
