What is Workability of concrete ?


The ease with which the concrete can be mixed up with minimum quantity of water, transported, placed and compacted without segregation and bleeding is called workability.

Workability is defined as the property of concrete which determines the amount of useful internal work necessary to produce full compaction. workability concrete is one which exhibits very little internal friction between particle and particle.

The factor helping concrete to have more lubricating effect to reduce internal friction are as follows:-

a. water content

b. mix proportion

c. size of aggregate

d. surface texture

d. shape of aggregate

f. grading of aggregate

g. use of admixture.
