The Effect of SAP and POSS Additives on the Durability of Concrete in Artic Environments
In an on-going European project LORCENIS, which focus on the development of durable concrete structures, different types of innovative additives have been tested for use in concrete. As a part of this project the effect of super absorbent polymers (SAP) and polyhedral silsequioxanes (POSS) on differ...

In an on-going European project LORCENIS, which focus on the development of durable concrete structures, different types of innovative additives have been tested for use in concrete.
