Slump Test of concrete [5 Step by Step] Procedure

Tests on Concrete - Concrete Slump Test, Compression Test

Procedure of slump test for concrete: Clean the cone. Dampen with water and place on the slump plate. The slump plate should be clean, firm, level and non-absorbent. Collect a sample of concrete to perform the slum test. Stand firmly on the footpieces and fill 1/3 the volume of the cone with the sample. Compact the concrete by 'rodding' 25 times.

How To Do Slump Test Of Concrete?

Here are the steps to do the slump test of concrete. 1. Get a concrete sample. When a truck mixer reaches the checkpoint, the quality engineer should check the delivery note to ensure that the concrete delivered is in compliance with the concrete grade required for the concrete element to be cast. Roll the drum for a certain time to completely mix the concrete inside.

For concrete with slump 1-inch (25-mm) or higher, either rodding or vibrating is permitted. Determine the number of layers of concrete to be placed in the mold For concrete to be consolidated with the tamping rod, place concrete in 3 equal layers for 6 ´ 12-inch cylinders; and in 2 equal layers for 4 ´ 8-inch cylinders

QUALITY CONTROL IN CONCRETE CONSTRUCTION WORK

Workability of concrete is an important property of concrete while concrete is in its fresh state. Therefore slump test or compaction factor test should be performed to check workability of concrete. About three tests should be carried out for every 25 m 3 of concrete.

Modified Slump Test to Measure Rheological Parameters of

The apparatus and test procedure are described. Semi-empirical models are proposed for the yield stress and for the plastic viscosity as function of the final slump and slumping time. The application of the modified slump test for the evaluation of the viscosity is limited to concretes with a slump of 120 to 260 mm.
