MasterGlenium SKY 675

High Range Water Reducing Admixture for Concrete
EN 934-2 T 3.1 / 3.2

Material Description

MasterGlenium SKY 675 is an innovative second-generation superplasticizer based on polycarboxylic ether (PCE) polymers. It is derived directly from the Total Performance Control concept. MasterGlenium SKY 675 is specially engineered for ready-mix concrete. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them efficiently. As compared with other PCE superplasticizers, it is possible to obtain a high quality concrete mix with accelerated strength development and extended workability without delayed setting characteristics.

The molecular structure of MasterGlenium SKY 675 is effective in early strength development. Conventional super plasticizers completely wrap cement particles and prevent them from joining with water by forming a barrier. By this way, the hydration process becomes slower. Differently from this mechanism, MasterGlenium SKY 675 molecules leave gaps on cement particles that allow sudden hydration. These gaps enable early high strength development.

The Total Performance Control concept ensures that ready-mix producers, contractors and engineers get a concrete that is of the same high quality as originally specified; starting from production at the batching plant, to the delivery and application into place, and followed by its hardening process. Utilizing Rheodynamic concrete technology it provides a concrete mix with exceptional placing characteristics and accelerated cement hydration for early strength development and high-quality concrete.

Areas of Application

MasterGlenium SKY 675 is used in the production of high-quality ready-mix concrete.
MasterGlenium SKY 675 may be used in combination with MasterMatrix admixtures for producing Rheodynamic concrete, capable of self-compaction, even in the presence of dense reinforcement.
