Research ArticleOpen accessIn the author namesScanning Electron Microscopic Evaluation of Self-Compacting Concrete Spalling at Elevated TemperaturesMahmoud B. Alhasanat, Arabi N. Al Qadi, Omar A. Al Khashman, Ahmad DahamshehThis paper reports the effect of addition of Polypropylene (PP) fibers in the performance of Self-Compacting Concrete (SCC) under elevated temperatures. Various SCC mixtures were made with PP fiber at 0.0, 0.05, 0.10 and 0.15% by volume added. The specimens were exposed to elevated temperatures (200°C [392°F], 400°C [752°F] and 600°C [1112°F]). The microstructure of the matrix was investigated. This … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 7 Mar 2016 · 8,437 accessesView PDF Cite
