FLUIDITY means the property of concrete to flow where as
Workability means the property of concrete with which it
can be mixed,transported,placed and compacted easily into
the required shape OF Structural member. Plasticzers
increase the workabilty as well as fluidity of concrete

Answer / Sunny Mehrotra

Fluidity refers to the ability of a material to flow under stress. High fluidity means the material can be easily deformed, while low fluidity results in poor flow properties.nWorkability, on the other hand, is the ease with which a material can be processed without damaging it. It includes properties like compressibility and stretchability.nPlasticizers work by reducing the intermolecular forces between polymer chains, making the plastic more flexible and easier to process. Common plasticizers include phthalates, glycols, and adipates.

i know that, the for calculating material required for concrete volume of concrete is taken 50-54 % more for wet volume. i have querry is that cement and sand volume taken more for making wet volume but in the case of aggregate why it is taken more there is no change in aggregate whether it is dry or wet.???? can you give me answer for this???
