PRODUCT DESCRIPTION
PSR™ is a highly efficient additive specifically designed to extend the setting time of concrete. This product falls under the retarders group and contains a combination of carefully selected ingredients, including lignosulfonates, sugars, hydroxycarboxylic acids, salts, and other organic compounds.
Incorporating the PSR™ into concrete mixtures effectively delays the hydration process, allowing for better workability and increased control over the set time. This is particularly advantageous for large-scale concreting projects, where a slower setting time is desired to accommodate complex construction processes and ensure optimal results.
The Powder Form Set Retarding is formulated for other concrete additives, such as strength accelerators, water reducers, superplasticizers, Humic acid groups, sulfonic acid, Amino acids, and alkali metal salts. These complementary components contribute to the overall performance and fluidity of the concrete mixture.
Notably, urea is an excellent retarder, while lignosulfonate exhibits retarding action in concrete. These specific properties make the PSR™ code an exceptional choice for achieving desired setting times without compromising the ultimate strength and durability of the cured concrete.
With the Powder Set Retarder (PSR™ code), contractors and builders can confidently enhance their concrete construction projects, ensuring improved workability and precise control over the concrete’s setting time.
