Abstract

This paper presents the detailed experimental studies on Durability characteristics on carbon nanotubes concrete modified with carbon and polypropylene fiber integrated with High performance concrete (HPC) of grade M60, which reviews advancement in the field of fiber reinforced cementitious composites. Cement concrete is a great source for the construction of buildings, bridges,dams and infrastructures etc., because of its high compressive strength but it has resistance to limited tensile and flexural strength. Thus, for improving its properties, cement concrete is reinforced with fibers, carbon nanotubes (CNTs) and polypropylene fibers. CNT reinforced cement concrete enhances tensile and flexural strength in comparison to fiber reinforced cement composite materials. Though significant research has not been done in this area over the past decade, but more challenges are need to be addressed. For durability tests Acid attack, Sulphate attack and Water absorption are performed as per the specifications of ASTM. The test specimen consists of M-60, M-60+CNT, M-60+CNT+PF, M-60+CNT+CF, M-60+CNT+PF+CF concrete matrices. The present experimental results have shown that there is an improvement in durability properties in concrete by incorporating carbon fiber, Carbon Nano Tubes and polypropylene fiber. It has been recognized as a finer reinforcement which can reduce water absorption and increase acid and sulphate attack resistance of concrete matrices. The results proved that the durability has improved for M60+CNT+PF+CF in comparison with other concrete matrices.
