  • What are plasticizer admixtures?
  • These admixtures are known as plasticizers. The combination of organic substances or combinations of organic and inorganic substances which cause reduction in water content for a given workability or give a higher workability at the same water content are known or termed as plasticizer admixtures. These are used for the following proposes: 1.
  • What types of plasticizers can be used in concrete?
  • Several types of plasticizers can be used in concrete, including water-reducing plasticizers, superplasticizers, and retarding plasticizers. Water-reducing plasticizers reduce the amount of water needed in the concrete mix, while superplasticizers can increase the workability of the concrete without increasing the water content.
  • Why do plasticizers increase the strength of concrete?
  • The dispersing ability of plasticizers (water reducing admixtures) results in a greater surface area of cement exposed to hydration. For this reason there is an increase in early strength of concrete than that of admixture free concrete of the same water/cement ratio.
  • What are admixtures used for?
  • Admixtures are used to modify the properties of concrete or mortar to make them more suitable to work by hand or for other purposes such as saving mechanical energy. Water reducing admixtures (WRA) The use of WRA is defined as Type A in ASTM C 494.
  • 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 concrete admixtures?
  • Read More on Concrete Admixtures Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance ...
