  • What are concrete plasticizers?
  • Concrete plasticizers, also known as water-reducing admixtures or superplasticizers, are chemical additives that play a crucial role in enhancing the workability and properties of concrete. By reducing the required water content for a given workability level, plasticizers offer numerous benefits, including:
  • Can super plasticizer and retarder improve concrete workability?
  • Alsadey (2013) investigated the effects of super plasticizer and retarder on the properties of concrete with a specific strength of 30 MPa. The results showed that the workability of concrete could be improved by adding a super plasticizer and a retarder. ... ...
  • What is the difference between retarding admixtures and plasticizers?
  • Retarding Admixtures: These admixtures delay the setting and hardening of concrete, extending the time available for placing and finishing. They are particularly useful in hot climates or for large concrete pours. Plasticizers, on the other hand, typically accelerate setting.
  • What is a superplasticizer admixture?
  • Superplasticizers as high-grade water reducer admixtures are made of synthetic water-soluble macromolecules which are largely utilized in concrete mixtures 1, 2, 3, 4.
  • What are plasticizing cementitious admixtures?
  • 3.1. Chemical stability of admixtures in AAC: FTIR analysis Plasticizing cementitious admixtures are designed to improve the properties of Portland cement, which is hydrated with water that has a neutral pH. On the contrary, in AAC, solutions with higher pH are needed to hydrate/activate the cement.
  • 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.
