Set Retarding Chemical Admixture for Concrete
Nanoplaster R is a set retarding chemical admixture specially designed for concreting operationswhich retarding of setting time is needed.
Use
Nanoplaster R is recommended for use in the applications and purposes below.
Any type of concreting operation requiring extended setting time of fresh concrete.
Continuous and large volume concreting operations like mass concrete applications.
Concreting operations that cold joint formation is undesirable.
Concretes to be transported to long distances.
Concreting works requiring extended time for placing, vibrating and surface finishing operations.
Concreting operations requiring re-vibration.
Operations in hot weather conditions.
Advantages and Properties
Nanoplaster R significantly extends the initial and final setting time of cement. It is suitable for use in all concreting operations where the fresh concrete must be remained in plastic stage for longer time.
Provides easiness in large-volume and continuous concreting operations requiring advanced planning in production, transportation, pumping, placing, vibrating and surface finishing of fresh concrete.
Reduces cold-joint formation risk in layered mass concrete production.
Provides advantage in continuous mass concrete production by keeping the first layer concrete still capable of deforming as the upper layers being successively placed in a long time.
Nanoplaster R has a water reduction property of around 8% – 10% as a secondary effect.
Enhances workability and ultimate strength of concrete.
Does not contain chloride or any other substances that may cause corrosion.
