Abstract:In this research, the effects produced by the combination of coffee husk ash and polypropylene fibers in the production of concrete were studied in order to evaluate the mechanical properties and determine an optimum design combination. Two standard concrete mix designs of f'c= 210 and 280 kg/cm2 were developed, and experimental treatments of standard concrete were designed by adding coffee husk ash at 5%, 10% and 15% combined with polypropylene fibers at 1%, 2.5 % and 5%. The results showed that the resistanc… Show more
