SLUMP TEST

INTRODUCTION

The slump test is a means of assessing the consistency of fresh concrete. It is used, indirectly,
as a means of checking that the correct amount of water has been added to the mix. The test is
carried out in accordance with BS EN 12350-2, Testing fresh concrete. Slump test. This
replaces BS 1881: Part 102. [ CITATION Slu661 \l 17417 ]

The slump test is perhaps the most widely used because of the simplicity of the apparatus
required and the test procedure. The reason for the popularity of the slump is that the
equipment is light and portable and the test is simple and easy to carry out. The slump test
indicates the behaviour of a compacted concrete cone under the action of gravitational forces.
The slump test is a practical means of measuring the workability. Changes in the value of
slump obtained during a job may indicate changes in materials, in the water content or in the
proportions of the mix, so it is useful in controlling the quality of the concrete produced.
The test carried out with a mould called the slump cone. The slump cone is placed on a
horizontal and non-absorbent surface and filled in four equal layers of fresh concrete, each
layer being tamped 25 times with a standard tamping rod. The top layer is struck off level and
the mould is lifted vertically without disturbing the concrete cone. The subsidence of concrete
in millimetres is termed the slump. After the test, slumps evenly all around is called true
slump. In the case of very lean concrete, one half of the cone may slide down the other which
called a shear slump or it may collapse in case of very wet concretes. The slump test is
essentially a measure of consistency or the wetness of the mix. [ CITATION Slu14 \l 17417 ]

OBJECTIVE
To determine the effect of slump on different water/cement ratio and concrete mix.
