Civil Lab Equipment Manufacturer J Ring Test Narrow Gap with model is manufacturers as per the industry defined EN 12350-12 standards. J Ring Test Narrow Gap are the commonly required in the laboratory.

The use of J-Ring test is for determining the passing ability, the flow spread and the flow time of self-compacting concrete as per concrete flows through the J Ring apparatus. The J-Ring narrow gap with ø18 mm x 16 smooth bars is manufactured from mild/stainless steel.

The Slump Cone is made from sheet steel which is protected against corrosion, with diameters; top 100 millimetre and base 200 millimetre and with a height of 300 mm. The Base plate is 900x900x3 millimetre square, made of mild/stainless steel with engraved circles of 200 mm and 500 mm diameter conforming to the EN 12350- 8 standard. The 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 J-Ring with narrow gap and slump cone.
