Workability of Concrete - Definecivil - Civil Engineering ...

Aug 20, 2019  The word “workability” defines an amalgam and composite of four concrete flow-making physical properties like mixability, transportability, mouldability, and compatibility. You can’t ignore this physical parameter because of the fact that it effects the strength, durability, cost of labor, compaction effort, and also the final appearance.

Factors Affecting Workability of Concrete - Civil Engineering

Rich concrete mix (cement content is high) is more workable because due to sufficient cement aggregates will have proper lubrication for easy movement which means more workability. Size of Aggregates Finer particles require more water for a larger surface, hence aggregate with finer particles need more water to make it workable.

Workability of concrete and admixtures Civil Engineering

Workability requirements for a concrete mix tend to conflict with requirements for maximum strength, density and economy, since workability increases with increased fines, cement, or water in a mix, but increased fines and water reduce density and strength, while increased cement may increase shrinkage and liability to cracking as well as adding to the cost of a mix.

Sep 07, 2011  Workability can be measured by the concrete slump test, a simplistic 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.The cone is placed with the wide end down onto a level, non-absorptive surface.
