Impact of nano admixture to improve the durability and strength of concrete

Abstract

Nano additives contains various supplementary cementations materials SCMs such as silica fly ash clay and slag are used to improved concrete properties New Nano modifies a Nanometer nm is 10 9m with possible applications in concrete technology have the fine grinded particle size that is less than hundred nm Nano additives of smaller in size and great potential to expose in large surface area Nano materials are very reactive in connection with improving concrete performance such as mechanical strength durability properties of concrete The thesis highlights the details of development of Nano modified concrete NMC The NMC enhance the quality of Nano modified concrete mix is evaluated through various strength properties like compressive strength split tensile strength flexural strength and deflection and crack behaviour of concrete and durability tests like Water Permeability Test WPT water absorption test bond strength of concrete by pullout test saline and alkaline attack test are carried out to analyse the performance of NMC The objective of this present investigation is to evaluate the structural strength of Nano modified concrete by Nano silica and Nano clay material as supplementary cementitious material and potential use of non destructive testing devices for in situ strength parameters of NMC during and after construction The concrete specimens of different for different mix proportions were analysed in the study newline
