15 Types of Admixtures Used in Concrete - The Constructor
Calcium, sodium and ammonium lignosulphonates are commonly used plasticizers. Some of the new generation super plasticizers are acrylic polymer based, poly carboxylate, multicarbovylatethers etc. Fig 1: Water Reducing Admixture 2. Retarding Admixtures

STUDY OF CONCRETE WITH VARIOUS TYPES OF PLASTICIZERS AND
Practical value of common concrete water-cement ratio moves within 0.35 to 0.60 depending on type and effect of added plasticizers or superplasticizers and required consistency of fresh concrete. Low water-cement ratios that may get under 0.25 is use namely with new modern types of concrete like RPC
Plasticizers For Concrete - Principle, Types & Advantages
Advantages of Plasticizers in Concrete. Improves workability of concrete without the addition of extra water. Improves the strength of concrete without increasing the cement content. Increase the strength characteristics of the finished concrete foundation by twenty five percent. Plasticizers make the compaction easy without the use of vibrators.

- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- What is a plasticizer in concrete?
- and more resistant to cold. A plasticizer is an additive used in concrete to improve its workability, performance, and durability. Plasticizers are typically added to concrete mixes to make pouring, shaping, and finishing easier. They can also help to increase the strength and reduce the permeability of the hardened concrete.
- How do plasticizers and water reducers affect concrete strength?
- Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength.
- What is a hydrophilic plasticizer?
- The primary purpose of hydrophilic plasticizers is to improve the concrete’s plastic and flow properties, as evidenced by their increased wet ability. This plasticizer makes a lot of air get into the concrete mix. It is possible to lower the tension of the water in the solution and make the concrete more flexible.
- What makes a good plasticizer?
- A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
- How do Plasticizers make concrete stronger and last longer?
- Plasticizers make concrete stronger and last longer by reducing the amount of water and cement needed to reach a certain level of workability. Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable.
