Concrete Slump Test Apparatus

Product Description

Slump Test Apparatus: MTCT-123

The oldest most widely used test for determining workability. This test is used to determine the workability of fresh concrete, which would normally be undertaken at the point of delivery to ensure the concrete, is of adequate consistency for placement. The test is applicable to concrete of medium workability. The device is a hollow cone-shaped mould. The mold is filled in three layers of each volume. Each layer is rodded with a 16mm steel rod 25 times. The mould is then lifted away and the change in the height of the concrete is measured against the mould. The slump test is a measure of the resistance of concrete to flow under its own weight.
