CECMAT - Concrete Part 3

the only slump that can be measured in the test. The measurement is taken between the top of the cone and the top of the concrete after the cone has been removed

the indication of very low water-cement ratio, which results in dry mixes. These type of concrete is generally used for road construction

This is an indication that the water-cement ratio is too high, i.e. concrete mix is too wet or it is a high workability mix, for which a slump test is not appropriate

indicates that the result is incomplete, and concrete to be retested.

CONSISTENCY (SLUMP) Maximum and Minimum: Reinforced foundation walls and footings

CONSISTENCY (SLUMP) Maximum and Minimum: Plain footings, caissons, and substructure walls

CONSISTENCY (SLUMP) Maximum and Minimum: Slabs, beams, thin reinforced walls & building columns

CONSISTENCY (SLUMP) Maximum and Minimum: Pavements and floor laid on ground

CONSISTENCY (SLUMP) Maximum and Minimum: Heavy mass construction

The ___ of a workable concrete mix depends upon the water-cement ratio.
