The Effect of Carbon Black, MWCNT and Carbon Fiber on Flexural behavior of cement nano composites

Abstract

One of the most popular and commonly utilised building materials is concrete. The recent studies of materials science explains influence of nano materials on cement composite at the macro, micro or structural level and their application in construction industry. In present study flexural behavior of cement nano composite containing nano materials such such as Multi-walled carbon nanotubes (MWCNTs) and Carbon fibers (CFs) and carbon black (CB) are studied. The various sample are prepared and flexural test is carried out. The flexural responses of plain cement beams and CB-CF- CNTs/cement beams were compared using single point bending tests results. The hybridization of MWCNTs, CFs, and Carbon Black coated with cement indicates improvement in mechanical properties compared to other samples. The SEM indicates the strong bonding between CFs, MWCNTs, and the cement matrix.
