SLUMP TESTWHAT IS A SLUMP TEST ?

A SLUMP TEST IS A TEST OF THE WORKABILITY OF CONCRETE

EQUIPMENT FOR SLUMP TEST :BASE PLATE

TROWEL TO MIX CONCRETE

STEEL TAMPING ROD

SLUMP CONE

RULER

H-3645_lg.jpgWORKABILITY OF CONCRETE THE WORKABILITY OF CONCRETE IS AFFECTED BY THE AMOUNT OF WATER IN THE MIX

TOO MUCH WATER CAN MAKE CONCRETE WEAK

NOT ENOUGH CONCRETE CAN MAKE THE CONCRETE TOO HARD TO WORK WITH

PROCEDUREPlace the cone on a level waterproof base

Place your feet on the holding down lugs

Place 75mm of concrete in the cone and tamp

25times

4. Repeat this action 3 more times until the cone is full and screed off the topCONTINUE :Gently lift cone from the concrete

Area cone beside concrete and put tamping rod

across the top of the cone

Measure down from the bottom of tamping rod of

top of the concrete

4.The measurement is the slump of the concretePic 5 Slump_4.jpgslump-test-0-inch.jpgloadbinary-blog.gifSlump test.pngAVERAGE SLUMPSWhat does a slump test measure ? WORKABILITY

What affects slump ? AMOUNT OF MIX WATER

How many time do you tamp a 75mm layer ofConcrete ? 25 TIMES

VE BETESTWHAT IS VEBE TEST ?

ITS DETERMINE THE WORKABILITY OF FRESHLY CONCRETE BY USING CONSISTOMETER APPARATUS

APPARATUS

.Ve-Be apparatus (consisting of vibrating table, slump cone)Cylindrical container,

Standard tamping rod,

Stop watch and

Trowels.

Vee-Bee ConsistometerVebe ConsistometerPROCEDURE :1. Same as slump test2. After the Slump test we can start ve-be test

3. Switch on the electrical vibrations and start the stopwatch. Allow the concrete to remold by spreading out in the cylindrical container. The vibrations are continued until the concrete is completely remolded, i.e., the surfaces becomes horizontal and the whole concrete surface adheres uniformly to the transparent disc.4. Record the time required for complete remolding seconds which measures the workability expressed as number of Vee-Bee seconds.vebe_consistometerAdvantages:
1. The Vebe consistometer is a dynamic test and can be used on concretes that are too dry for the slump test.

2. Test results are obtained directly.Disadvantages: 1. Due to the need to ensure that all vibration is kept within the test device, the size of the test device makes the Vebe consistometer generally unsuitable for field use.
2. The test device only works for lowslump concretes.THANKYOUClick to edit Master title style
