Abstract

This research presents the results from an experimental study on the optimum amount of polypropylene (PP) to be used in self-compacting concrete (SCC) to prevent spalling when exposed to elevated temperatures, taking into consideration the characteristics of SCC, and the length and thickness of the fibres. A target compressive strength of 45MPa was taken to test the addition of PP fibres. The temperature during the test was recorded at 200, 400, and 600°C and fixed (time recorded when it reached the testing temperature) for 2 and 4 hours. After the test, the condition of the samples was evaluated and tested to determine the residual compressive strength of the SCC. Results from the research show the workability of PP fibers, within the fresh properties of SCC. Also, it indicated that 0.05 % and 0.10 % of 19 mm PP respectively per volume of concrete is required to prevent the spalling of SCC when subjected to elevated temperatures. The susceptibility of the SCC to spalling increases with the degree of ingredient materials used in the SCC.
