The difference between the slump flow and j-ring flow is an indication of the passing ability of concrete. The least method is applicable for laboratory use in comparing the passing ability of different concrete mixture. It is also applicable in the field as a quality control test. It can also be used to investigate the resistance of SCC to segregation by comparing test results from two different portions of the sample. The j-ring test measures three parameters: flow spread, flow time, and blocking step. The j-ring flow spread indicates the restricted deformability of SCC due to the blocking effect of reinforcement bars and the flow time indicates the rate of deformation within a defined flow distance. The blocking step quantifies the effect of blocking.
The equipment consists of the following replaceable parts:

I recently purchased a Servo Compression Automatic Compressive Machine 3000kN from Vertex and I couldn’t be more pleased. The instrument is of high-quality and helps to accurately measure the strain distribution in the preforms. It is easy to use and produces reliable test results.
