This study reports the results of an investigation of a steel fibre-PVA hybrid UHPFRC mix under elevated temperature. A specially designed furnace loading frame was assembled, facilitating simultaneous heating and loading of the specimens. The specimens consisted of 100 mm diameter by 200 mm high cylinders. The cylinders were first loaded in compression to their specified load of zero or 14 per cent or 28 per cent of their strength measured under ambient conditions and then gradually heated to 600oC. The changes in strain were measured; the free thermal strains were found to be similar to that of a siliceous aggregate concrete and the ‘transitional thermal creep’ are significant when the temperature increases above 250°C.
