Abstract
Results of uniaxial compressive strength measurements taken on 1210 unsealed cement paste and concrete specimens heated to temperatures up to 600°C are reported; they show that both material and environmental factors have a significant influence during the heat cycle and afer cooling. The best results were obtained using firebrick aggregate and a cement blend containing 65 % slag replacement of OPC by weight. At 600°C the “hot” compressive strength of this material was 85% of the value measured before heating.Keywords
