摘要：

Results of uniaxial compressive strength measurements taken on 1210 unsealed cement paste and concrete specimens heated to temperatures up to 600-degrees-C are reported, they show that both material and environmental factors have a significant influence during the heat cycle and after cooling. The best results were obtained using firebrick aggregate and a cement blend containing 65% slag replacement of OPC by weight. At 600-degrees-C the 'hot' compressive strength of this material was 8.5% of the value measured before heating.
