Behavior of High Performance Fiber Reinforced Concrete Using Carbon Nano Tubes

Abstract

The construction sector is moving towards a new era by extreme use of high-performance concrete (HPC). The use of HPC is not limited to infrastructure projects, but also to high-level facilities such as nuclear reactors, defense structures etc., Addition of fibers to HPC increases toughness, energy absorption capacity. Study relating to the static and dynamic behaviour of reinforced cement concrete beam, modified with different composite materials like, Carbon Nano tubes, Steel fibers, Polypropylene Fibers and SBR latex is receiving much more attention among the research community in the recent years. Therefore, an effort was made to study the effects of composite materials through current experimental research. newlineConcrete is made to behave in a ductile manner so that the member can absorb and dissipate large amount of energy. The reasons mentioned above have attracted many researchers and their investigations have led to the development of new construction materials like high performance concrete integrated with Carbon Nano Tubes, fibers such as polypropylene fibers, steel fibers and use of polymer like SBR-latex. newlineStrength and ductility are the two major factors to be considered in the design of structures subjected to static and dynamic loads. In the recent past, many new materials have been tried which exhibit higher strength and durability than conventional concrete, so that they could be used in the case of structures subjected to static loads and dynamic loads such as seismic loading, impact, blast loading, cyclic loading etc., Composite materials offer definite advantages over the conventional materials with their high specific modulus. newlineThe situation becomes more critical for the condition of low-velocity impact. This has been considered in the recent years as an important study. newline
