Desirable Workability for Construction. Desirable workability depends on two factors which are: Section size, amount and spacing of reinforcement: When a section is narrow, complicated, several narrow corners, inaccessible parts; a highly workable concrete is desirable to obtain full compaction through a reasonable amount of effort. When the section is crowded with steel reinforcement and ...

20-08-2019  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.

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.

01-05-2020  1.2 Slump Test With K-Slump Tester. Very recently a new apparatus called “K-Slump Tester” has been devised. It can be used to measure the slump directly in one minute after the tester is inserted in the fresh concrete to the level of the floater disc. This tester can also be used to measure the relative workability.

CIVIL ENGINEERING: CONCRETE TECHNOLOGY (WORKABILITY

07-09-2011  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.
