Workability can be measured by the concrete slump test, a simple measure of the plasticity of a fresh batch of concrete following the ASTM C 143 or EN 12350-2 test standards. Slump is normally measured by filling an ” Abrams cone ” with a sample from a fresh batch of concrete.

What is the workability of concrete? Put in simple terms, it is the property of the concrete that determines or describes the ease of working with it. It is related to the ease of getting it into the formwork, and flow and ease of compaction.
INTRODUCTION. Self-compacting concrete (SCC) was first developed in Japan in 1988 to reduce labor in the placement of concrete, by eliminating or reducing the need for vibration to achieve consolidation . Therefore, the main property that defines SCC is high workability in attaining consolidation and specified hardened properties.

Workability of Concrete by Slump Test Which brings us to what is by far the most popular (some say overused) measure of workability. The slump test originated as a way for workmen to judge how easy their day was going to be using freshly mixed concrete.
Regarding hardened concrete properties, density of concrete was measured, between 1.9 and 2.1 g/cm³, depending on the aggregate and binder. Compressive strength and Ultrasonic Pulse Velocity are significantly affected by the type and proportions of raw materials in the mixtures.
A.2 Test Description For commercial production purposes it is important to assure that the final concrete mix design yet to be determined has a similar workability as the mix currently used by Kistner Concrete
Workability. of concrete is mainly affected by consistency i.e. wetter mixes will be more workable than drier mixes, but concrete of the same consistency may vary in workability.
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows.
