  • 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.
  • What are concrete plasticizers & high strength plasticisers?
  • Concrete plasticizers are also known as water reducing admixtures and high strength plasticisers are also known as high superplasticizers. Increasing the workability of the concrete allows a lower water content to be used which improves strength and durability of the hardened concrete.
  • Can Plasticizers improve concrete permeability?
  • Plasticizers can improve concrete’s resistance to sulfate attack, corrosion, and freeze-thaw cycles. This is attributed to the denser microstructure and reduced permeability of concrete with lower water-cement ratios. Plasticizers promote better surface hydration, leading to smoother and denser concrete surfaces.
  • 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.
  • How much plasticizer should be used in concrete admixture?
  • Typical plasticizer dosage rates range from 0.3-1.5% by weight of cementitious material. Overdosing can negatively impact strength. Trial batches should be tested. There are several classes of plasticizers are used as admixture in concrete . some important types of plasticizers used in concrete:
  • How do you mix plasticizer with concrete?
  • Mixing and Placement: Properly mix the plasticizer with the concrete mix according to the manufacturer’s instructions. Ensure adequate mixing time to achieve uniform dispersion and avoid localized effects. Curing Procedures: Follow appropriate curing procedures for the specific concrete mix and environmental conditions.
