StenMix® SUPA 280 is a polycarboxylic ether (PC) based, high-range water-reducing, high-performance superplasticizing concrete admixture. It contains no chlorides or any other components that may cause corrosion of reinforcement. It conforms to the requirements of EN 934-2 Table 11.1 & 11.2 and ASTM C 494/C 494M Type A and Type F.
Areas of Use
StenMix® SUPA 280 is used in the production of flowable concrete to improve surface quality and density. It is especially suited to densely reinforced slabs, foundations, ceilings, walls, beams and columns where extended and controlled setting times are required at high ambient temperatures.
Added to ready-mix concrete it provides excellent workability, eliminates the risk of segregation during transport and placement, and reduces the vibration required.
