Recent years have seen a tendency towards increasingly slender structures designed with the use of high performance concrete. Application concrete is also growing in tunnel construction. One most important challenges to control explosive spalling and method recommended by Eurocode 2 addition polypropylene fibres mix. The purpose research described this paper was evaluate changes physical mechanical properties HPC exposed effect temperature. tests were carried out on three types high-performance concrete: air-entrained concrete, fibre-reinforced reference having constant water/cement ratio. hardened including compressive strength, tensile splitting flexural strength E-modulus studied. latter both cured at 20̊C subjected high-temperature conditions 300̊C, 450̊C 600̊C. results enabled us compare effectiveness two methods improve entrainment air.
