Design of fire resistant self-compacting concrete containing PP fibers

Abstract

Present paper deals with a challenge of formulating fire resistant self-compacting concrete with polypropylene fibers. Firstly, influence of fiber on fresh state behavior is evaluated and predictive scheme for the yield stress is developed. Secondly, choice of PP fiber geometry is optimized in terms of spalling prevention for three cementitious materials via numerical and experimental works. Lastly, fire resistant self-compacting concrete with PP fibers is designed using conclusions from rheology and fire behaviour.
