Abstract. The objective of this paper was to study the influence of different length and dosage of polypropylene fibres on the properties of self-compacting concretes at elevated temperatures. A total of five self compacting concretes and one normally vibrated concrete were produced. The poypropylene fibres were of different length (12 mm, 6 mm and 3 mm) and were added at dosages of 1.0 Kg/m 3 and 0.5 Kg/m 3 . The properties measured after fire exposure were the compressive strength, splitting tensile strength and water capillary absorption. The best overall performance was observed on the fibre reinforced self compacting concrete produced with the 6 mm HPR fibres at a dosage of 0.5 Kg/m 3 .

SUMMARYConcrete as a construction material is likely exposed to high temperatures during fire. The retained properties of concrete after such exposures are still of great importance in terms of the serviceability of structures. This paper presents the effects of high temperatures on the physical, mechanical, and microstructural properties of concrete. Specimens with different sizes were exposed to high temperatures ranging from 200 to 1200 • C. The compressive strength, splitting tensile strength, ultrasonic pulse velocity, and rebound numbers of the specimens were determined. The microstructures of the specimens were examined by scanning electron microscope (SEM) analyses. The test results indicated that the retained compressive strength of concrete considerably decreased with increase in temperature. The effect of specimen size on the retained compressive strength was not pronounced. The retained splitting tensile strength of concrete remarkably reduced as the temperature was increased. The specimen size played an important role on the retained splitting tensile strength of concrete up to 400 • C. The test results revealed that ultrasonic pulse velocity (UPV) test can be successfully used in order to check the uniformity of fire-damaged structures. The rebound numbers decreased with increase in exposure temperature. SEM studies on specimens exposed to 800 • C revealed significant changes in the microstructure of the concrete.

“…The heating temperature is 100, 300℃, the rate of strength loss were 15%, 20%, the loss of strength increases with the increase of the concrete grade. Poon [12] the studied the mechanical properties of different content of steel fiber concrete after high temperature by static load test, and found that steel fiber can significantly improve the residual compressive strength of high strength concrete after high temperature. When the dosage of steel fiber volume fraction is 1%, The compressive strength of steel fiber high strength concrete after 600℃ high temperature is 50% of compressive strength of high strength concrete at room temperature.…”
