Abstract

Construction industry is heading towards a new era with intensive use of High performance concrete (HPC) which overcomes the limitations of conventional concrete. Nanotechnology is an emerging field of material science related to the understanding and control of matter at the nanoscale. The addition of fine nano particles can improve the properties of concrete due to the effect of increased surface area on reactivity and through filling the nano pores of the cement paste and also leads to an increase of both short-term strength and long-term strength. The present study aims to investigate the integration of Carbon Nano tubes ( CNTs )polypropylene ,steel fibers and SBR Latex with HPC of a designed mix of M60 grade of concrete. The influence of the cementations material dosage, nano material, cement/ultra-fine ratio, percentage of fibers, and the mixing procedures on the mechanical properties of nano based carbon concrete was studied. Carbon Nano tubes were first dispersed in water and surfactant using an ultrasonic mixer as per state-of-the-art techniques and then combined with SBR Latex and fibre reinforced high performance concrete. The various mechanical properties like Compressive, Flexural and Split tensile strength can be improved with the addition of low concentrations of CNT in SBR Modified high performance fiber reinforced concrete.
