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.
Alsta Nautoscaph Superautomatic Reissue — Is It Worth It?
Here, however, the Alsta Nautoscaph Superautomatic has admittedly great aesthetics mixed with average component quality and an NH35 movement, with a retail price of 878.41 on the bracelet. There’s no way around it; that’s a lot of dough. This is not a lost cause I don’t like to be scathing. It doesn’t give me any pleasure.
Superplasticizer
Superplasticizer. Superplasticizers ( SPs ), 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.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.

- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling 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. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
- What is a superplasticizer admixture?
- Superplasticizers are a relatively new category of admixtures utilized for gaining higher strength at lower water/cement ratios. Mostly, these are chemical admixtures and interact with cement. Superplasticizers are chemically different from normal water reducers and are capable of reducing water content up to about 30%.
- Are superplasticizers good for concrete?
- Superplasticizers, owing to the reduction in the water–cement ratio, decrease the penetration of chlorides into concretes and also improve the resistance of concrete against salts. For the same reason, the resistance to sulphate attack is also increased.
- Which superplasticizer is the most efficient?
- It has been shown that Poly-carboxylic ether type (PCE) superplasticizers are the most efficient in their job. Souza et al., showed that these PCEs are a new type of superplasticizer with a great water-reducing capacity allowing a w/c ratio as minimum as 0.20.
- Can a superplasticizer be used to reduce water content?
- The use of superplasticizers allows this water reduction without affecting workability. Water reduction of up to 30% can be achieved and concrete with a w/c ratio below 0.28 has been placed successfully. Superplasticizers can be used to produce concrete with reduced cement content without changing the w/c ratio.
