The slump cone is filled with freshly mixed concrete and tamped with a tamping bar in four layers. The top of the concrete is leveled off with the top of  the slump cone., the cone is lifted vertically up and the slump of the sample is immediately measured.
Base has clears on its underside to help dig into the ground surface .
Positive clamping of slump cone to the base while filling and tamping the concrete.
A combination swivel carrying handle also serves as the datum making the conventional and somewhat awkward measuring procedure of using a foot rule and a datum bar , a thing of the past.

J-Ring
Ref. Standard : ASTM C1621

EKE 334J:

These tests are used to determine the flow ability and passing ability of Self – Consolidating Concrete (SCC) as defined in ASTM C1621. Passing ability refers to the ability of SCC, under its own weight (without vibration) , to flow into and completely fill the spaces within an intricate , containing obstacles such as reinforcement bars.

This test method provides a procedure to determine the passing ability of self-consolidating concrete mixtures. The difference between the slump flow and J-Ring flow is an indication of the passing ability of the concrete. The test 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 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 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.

Passing ability refers to the ability of SCC, under its own weight (without vibration) , to flow into and completely fill the spaces within an intricate , containing obstacles such as reinforcement bars.

L Box to investigating the flow rate and passing ability of SCC (Self – consolidating concrete) in confined spaces.  It measures the reached height of fresh SCC after passing through the specified gaps of steel bars flowing within a defined flow distance. With this reached height, the passing or blocking behavior of SCC cam be estimated.

U-Box

EKE 334U:

These tests are used to determine the flow ability and passing ability of Self – Consolidating Concrete (SCC) as defined in ASTM C1621. Passing ability refers to the ability of SCC, under its own weight (without vibration) , to flow into and completely fill the spaces within an intricate , containing obstacles such as reinforcement bars.

The U shape Box is used to determine the confined flow ability and the capacity of SCC concrete to flow within confined space. The box is made of steel frame consisting of three bars.

In this test the degree of compatibility can be indicated by the height through an obstacles. The quality of the concrete can be judged by the height reached.

This made is a mechanical variation of the simple  slump test which includes determination of the workability of concrete. The concrete is formed in a slump cone positioned in a container, and it is vibrated after removing the cone on a small vibrating table operating at a fixed amplitude and frequency.
A plastic spacer disc in contact with the upper surface of the wet concrete guides the operator to judge when the compaction is complete. The time to complete the required vibrations gives an indication of the workability of concrete, which is expressed in Vee-Bee degrees.
