Character action


Glenium SKY superplasticiser was developed by Degussa to combine accelerated strength development with extended workability, without delaying the setting characteristics of ready-mixed concrete. It increases the slump, and maintains slump levels for up to two hours without adversely affecting the mix strength and durability. The polymer molecules do not entirely cover the surface of the cement grains, enabling hydration to start immediately, so giving high early strength development. It is anticipated that Glenium SKY will eventually replace a number of different additives used in different concrete applications.
