Behaviour of High Performance Reinforced Concrete Modified with Carbon Nano Tubes and SBR latex under Flexure

Studies on strength and ductility aspects of the concrete are constantly increasing and are one of the most developing areas in the design of concrete structures. High Performance Concrete (HPC) exhibits excellent strength and durability properties. Various factors such as adverse environment, climatic conditions, specific application, etc.demand the use of special type of concretes to meet the durability and performance requirements of infrastructures such as high rise buildings, dams, bridges, transportation terminal facilities like harbours, airports, etc. Detailed experimental investigation on flexural behaviour ofHigh Performance Concrete modified with Carbon Nano Tube (CNT) and Styrene Butadiene Rubber (SBR) latexon four test beam specimens having dimension 150mmx230mm with the effective length of 2000mm to obtain Load-Deflection response were carried out. The results of the study indicate that ductility factor, resistance to energy absorption capabilities and toughness index of CNT and SBR latex modified High Performance Concrete are enhanced significantly as compared to HPC.
