Difference Between Plasticizer and Superplasticizer

Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

When would you use a superplasticizer?

Superplasticizers can be used in three ways: to create flowing, self-leveling concrete without increasing water, without reducing cement and without sacrificing strength; to produce workable, high-strength concrete by reducing the water and thus the water-cement ratio; or, to save cement by reducing both the water and ...

What is the function of superplasticizer in concrete?

Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture.

What does plasticiser mean?

A plasticiser is a substance which when added to a material, usually a plastic, produces a product which is flexible, resilient and easier to handle.

What are Superplasticizers made of?

Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols.

Where do we use plasticizer?

Where do we use plasticizers? Explanation: Where low degree of workability is required like Deep beams, column and beam junctions.

Does plasticizer weaken concrete?

Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical used, use of too much plasticizer may result in a retarding effect.

What is plasticizer admixture?

Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

What does fly ash do in concrete?

Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added to concrete, the amount of portland cement may be reduced.

What is admixture concrete?

Concrete admixtures are natural or manufactured chemicals or additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength.
