The apparatus consists of a 700 mm square wooden top plate lined with a thin metal sheet, as shown in Figure. The plate is hinged on one end to a base, while on the other end, clips allow the plate to be lifted a vertical distance of 40 mm. Etched into the metal sheet are two perpendicular lines that cross in the center of the plate and a 200 mm circle concentric with the center of the plate. The frustum of a cone used to mold the concrete is shorter than the slump cone, with a top diameter of 130 mm and with a bottom diameter and height of 200 mm.

U Box test is used to measure the filing ability of self compacting concrete. The apparatus consists of a vessel that is divided by a middle wall into two compartments; an opening with a sliding gate is fitted between the two sections.
Reinforcing bar with nominal diameter of 134 mm are installed at the gate with centre to centre spacing of 50 mm. this create a clear spacing of 35 mm between bars.
The left hand section is filled with about 20 liter of concrete then the gate is lifted and the concrete flows upwards into the other section. The height of the concrete in both sections is measured.

Assessment of U Box Test:

This is a simple test to conduct, but the equipment may be difficult to construct. It provides a good direct assessment of filling ability. This is literally what the concrete has to do, modified by an unmeasured requirement for passing ability.

The 35 mm gap between the sections of reinforcement may be considered too close. The question remains open of what filling height less than 30 cm is still acceptable.


Equipment for U Box Test:

U box of a stiff non absorbing material

Scoop

Trowel

Stopwatch


Procedure for U Box Test on Self Compacting Concrete:

About 20 liter of concrete is needed to perform the test, sampled normally. Set the apparatus level on firm ground, ensure that the sliding gate can open freely and then close it.

Moisten the inside surface of the apparatus, remove any surplus water, fill the vertical section of the apparatus with the concrete sample.

Leave it stand for 1 minute. Lift the sliding gate and allow the concrete to flow out into the other compartment.

After the concrete has come to rest, measure the height of the concrete in the compartment that has been filled, in two places and calculate the mean (H1).

Measure also the height in the other equipment (H2). Calculate H1-H2, the filling height. The whole test has to be performed within 5 minutes.


Interpretation of The Result:

If the concrete flows as freely as water, at rest it will be horizontal, so H1-H2=0. Therefore the nearest this test value, the ‘filling height’, is to zero, the better the flow and passing ability of the concrete.

UsageV-Funnel Testing

The V-funnel flow time is the period a defined volume of SCC needs to pass a narrow opening and gives an indication of the filling ability of SCC provided that blocking and/or segregation do not take place; the flow time of the V-funnel test is to some degree related to the plastic viscosity.

Equipment:
  • V-funnel, as shown in Figure 7, made of steel, with a flat, horizontal top and placed on vertical supports, and with a momentary releasable, watertight opening gate.
  • Stopwatch with the accuracy of 0.1 second for recording the flow time.
  • Straightedge for levelling the concrete.
  • Buckets with a capacity of 12∼14 litres for taking concrete sample.
  • Moist sponge or towel for wetting the inner surface of the V-funnel.
