Superplasticizer: Types, Advantages Disadvantages

Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ...

How Super Are Superplasticizers? Concrete Construction ...

01/05/1982  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 cement contents while maintaining the same water-cement ratio and the

Use of Water Reducers, Retarders, and Superplasticizers.

Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete. Dosage needed for a concrete mixture is unique and determined by the

Superplasticizers and Segregation. By Concrete Construction Staff. Q.: What is the good of making a mix more fluid by adding a superplasticizer? I realize that the superplasticizing doesn't harm the strength by increasing the water-cement ratio, but what about increasing segregation? I think of a mix that flows as a mix that segregates and I'm very reluctant to use it. A.: It is reported that ...

Superplasticizer - Wikipedia

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. These additives are employed at the level of a few weight percent.

Raw Materials for Superplasticizers

Another alternative building block for superplasticizers are Clariant’s Polyglycol allyl ethers (Polyglykol A-type C). Like the Polyglykol ML grades these macromonomers can be directly polymerized, preferably to acrylic acid in water. The advantage for our customers: the avoidance of the ester reaction step saves time and cost, reduces complexity, and there is no formation of cross-linking ...

Superplasticizer - an overview ScienceDirect Topics

Superplasticizers can lead to increased air content when the mortar or concrete is mixed. This air may improve the workability to some extent but air contents of more than 3% for a non air-entrained concrete reduce durability and must be avoided. Therefore most superplasticizer formulations contain a defoamer – especially the ones based on lignosulfonates and PCEs.
