Abstract

The increasing demand for rigid pavements has necessitated the availability of cement concrete in which cement is the principal material. But production of cement is energy entringic. Using high volume fly ash, greater than 50% as a cement alternative has encouraged researchers as it reduces CO2 emissions by minimizing cement production. But low strength of high volume fly ash concrete (HVFAC) at early edges are the main barrier to replace the cement with significant amount of fly ash. Recently various nano materials have been extensively used to achieve sustainability goals in the HVFA concrete. This paper presence state-of-the-art review involving the uses of different nano materials for enhancing the property of high volume fly ash concrete. The effects of nano material on the green concrete mechanical as well as durability properties are analyze. It is demonstrated that nano materials including Nano –SiO2, Nano-Fe2O3, Nano Al2O3 Nano TiO2, CNTs, Nano Clay, Nano ZnO, GO, PCE etc. can be used effectively to enhance the micro structures, mechanical property such as compressive strength, flexural strength and split tensile strength of the modified concrete. It also improves their durability properties such as water permeability, sorptivity, antichloride penetration, anti errosion etc. this paper may provide deep insight into the role of different nano materials inclusion in the  concrete composite to enhance their overall properties.
