FIRE BEHAVIOUR OF PLAIN SELF-COMPACTING CONCRETE (SCC) BRANDVERHALTEN VON UNBEWEHRTEM SELBSTVERDICHTEN-

cosity-Agent Type and Combination Type were investigated with respect to their behaviour at fire conditions. Therefore cubes with an edge length of 300 mm without reinforcement were cast and subjected to a fire with a duration of 2 h according to ISO 4102 T. 2 after storage of 180 d. The spalling of the con-cretes depended on the (w/c)eq-ratio and the cement-powder ratio (c/p). The con-cretes showed a relatively high residual compressive strength which depended also on the (w/c)eq-ratio and the cement-powder ratio (c/p) of the mix.
