Concrete countertops: Using superplasticizer to increase
This quick demo shows how superplasticizer makes a high quality, low water to cement ratio concrete countertop mix workable, without adding any water. A low
Effect of Superplasticizers to Enhance the Properties of Concrete
This study aimed to study the effects of asuperplasticizing admixture, namely, Sikament-NN superplasticizer, on concrete properties, such as workability and compressive strength. Experiments...
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.

Concrete Admixtures: Superplasticizers The main purpose of using superplasticizers is to produce flowing concrete with a high slump in the range of seven to nine inches to be used in heavily reinforced structures and in placements where adequate consolidation by vibration cannot be readily achieved.
- Can superplasticizers produce high strength concrete?
- The use of superplasticizers may produce high strength concrete (compressive strength up to 22,000 psi). Superplasticizers can also be utilized in producing flowing concrete used in a heavy reinforced structure with inaccessible areas. Requirement for producing flowing concrete is defined in ASTM C 1017.
- Can superplasticizers improve cement flowability?
- Adding superplasticizers to cement provides remarkable improvement in cement and concrete flowability. Such improvement in flowability is, however, not compromised by a reduction in the compressive strength (which is a function of the water-to-cement ratio) of the resultant concrete.
- What is a superplasticizer used for?
- Superplasticizers are used to increase the fluidity of concrete without adding excess water. These molecules physically separate the cement particles by opposing their attractive forces with steric and/or electrostatic forces, as explained in Chapter 11 (Gelardi and Flatt, 2016). As a result, the concrete is easier to place.
- Do superplasticizers reduce water in concrete mixes?
- The benefits obtained by Superplasticizers in the reduction of water in the concrete mixes are best illustrated by the following examples. With PPC (Flyash based) conforming to IS:1489-part-I-1991. 7 days strength 38.5 N/mm 2.
- Is superplasticizer based concrete good for compressive strength test?
- For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability. Content may be subject to copyright.
- Are superplasticizers compatible with cement?
- Beyond these process parameters, the only real leverage on these superplasticizers is their molecular mass, in the range of 32–75 kD in the case of PNS (Spiratos et al., 2003). This only leaves a narrow range of variations, so that incompatibilities with cement should come mainly from the cement.
