“PARAMETRIC STUDY ON PERFORMANCE OF HIGH STRENGTH CONCRETE BY USING MULTI-WALLED CARBON NANOTUBES”

Abstract

Concrete is produced in variety of compositions, finishes, and performance characteristics to meet a wide range of needs. Concrete is used in structure to increase the strength, durability, and tensile strength. The concrete which is used had strength and durability then also High Strength Concrete (HSC) has introduced to increase the performance. Therefore for increasing more performance of High Strength Concrete (HSC) the researchers find additive material call Carbon Nano tubes (CNT’s). CNT had strength and flexibility which makes them of potential use in controlling other Nano scale structures, which suggests they will have an important role in Nano technology engineering. Multi wall carbon Nano tubes (MWCNT) is one type of CNT which is part of Nano technology which is going to be used in nowadays structure. It has a highest tensile strength of 63GPa which had been tested as per past study. Increasing the strength for longer duration of time and prolonging life along with giving boost to compressive strength and contributing to the tensile strength by improving the flexural strength is reported from earlier research work, when CNT’s are mixed with concrete. For effectively using MWCNT in concrete polycarboxylate ether super plasticizer is used as a surfactant in water with MWCNT to disperse them. Conducting an experiment on performance of high-strength concrete (M 65) by adding low concentration of MWCNT for finding compressive strength and durability. After using this additive material in concrete compared the relative performance of compressive strength and durability with the concrete material in which additive material (MWCNT) is not used.
