Self-compacting concrete ring J type
Blocking step concrete ring passing ability test apparatus
It is used for self-compacting concrete segregation resistance test. For determining the passing ability (measured by the blocking step) .the flow spread and T500J flow tome of the self-compacting concrete as the conrete flows through the J-ring
Technical parameters：
1.Rectangular cross section（30mm×25mm）Open ring
2.Vertical drilling, thread, can be reinforced（L:100mm,diameters:10mm,distance:48±2mm）
