Tenders Description & Specification for J Ring Apparatus
J Ring Apparatus
General Properties:
The J-ring test can be used to determine the passing ability of
self-consolidating concrete. It is applicable for laboratory use in
testing different concrete mixtures for passing ability or can be used
in the field as a quality control test. It is typical to also perform a
slump flow test with the J-ring test. This test is similar to the J-ring
except the J-ring is not used. The difference between the results of
the two tests provides an indicator of the passing ability of the
concrete.Designed for durability, J-ring set includes a slump cone,
J-ring with smooth or rebar rods and steel base plate with engraved
positioning rings.
The J-Ring test is used for determining the passing ability, the flow
spread and the flow time of self compacting concrete as the concrete
flows through the JRing apparatus. The J-Ring narrow gap with ø18 mm x
16 smooth bars is manufactured from stainless steel. The 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 Base plate is
900x900x3 mm square, made of stainless steel with engraved circles of
200 mm and 500 mm diameter conforming to EN 12350- 8. 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.
