wider sections and use of modern automatic batching plants to produce good quality of concrete. By literature review I have found that the hundred per cent compaction of concrete is an important parameter for contributing to the maximum strength. Quality produced concrete may still give poor results due to lack of compaction.
Plasticizers are chemical compounds that enable the production of concrete with ca. 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete.

It was concluded that the slump behaviors can be optimized based on the adjustments of the superplastisizer dosage.
In other words it has a property of enhancing workability at a given water-cement ratio in compare to concrete mix without Plasticizers. Plasticizers indirectly add strength to hardened concrete by enhancing workability of a concrete mix during its mixing and placing thereby allowing reduction in water-cement (W/C) ratio.
