EFFECT OF STRENGTH ON FINE BEHAVIOUR OF CONCRETE . NORDIC CONCRETE RESEARCH. PUBLICATION NO 8

The use of high strength concretes enhances the economy of structures, but this involves also a knowledge of their high temperature behaviour because the structures may be subjected to high temperatures (e.g. fire) and they must be correspondingly designed. High temperature behaviour of different high and ultra high strength concretes has been investigated. Studies comprised mechanical properties and the chemical and physical background of their alteration due to heating. The high strength concretes showed a stronger loss of strength and a higher risk of spalling than normal strength concretes.(A) For the covering abstract see IRRD 828653.
