Abstract

The study concentrates on the cyclic behaviour of concrete grade M25 with the addition of nanosilica powder and equal amounts of waste coir fibres and human hair. The results indicate that the improvement of cyclic flexural and number of cycles to failure, other than compressive, split tensile and static flexural properties, are effective and consistent up to a global 1.5% volume of the two waste fibres and 3% volume of nanosilica. Also crack patterns appear neater and suggest a higher ductility of the material, up to this limit of content filler, indicating that to increase it further work on the repeatability and consistency of introduction would be required.
