OBJECTIVES Abstract – Cement concrete is the most widely used construction material due to its low cost, easy availability of constituents along with high strength and durability. The global use of cement contributes to the carbon emissions. Cement production releases CO2 during its production process. Also, disadvantages such as low tensile and flexural strength coupled with brittleness promotes the addition of nanomaterials like graphene oxide. Graphene demonstrates a number of properties such as high flexibility, high tensile strength. This study investigates the feasibility of implementing graphene into the concrete matrix for improving its compressive and tensile or flexural strength.
The main objectives of this study are as follows: • To study the behavior of concrete with Graphene oxide. •To study the workability of Graphene oxide blended cement concrete. • To determine the compressive strength and tensile strength of Graphene oxide concrete. • To find out the optimum quantity of Graphene Oxide required to achieve maximum compressive and tensile strength of concrete.
The aim of this research is to study the performance of graphene oxide blended cement concrete, and also compare the compressive and split tensile strengths of M25 concrete by adding graphene oxide at various percentages. This paper investigates on the incorporation of graphene oxide in cement to improve its mechanical properties and thereby contributing to an alternative and sustainable practice in the field of construction.
3.SCOPE OF THE STUDY The conventional concrete mix has many drawbacks like less tensile strength, brittleness and causes great carbon emissions. By using graphene oxide as an additive in concrete, the mechanical performance and durability can be improved in a sustainable manner, ecofriendly and economical manner. The positive outcomes of graphene oxide blended cement concrete suggest promising applications in the field of construction that results in enhanced performance and reduced environmental impact. The findings underscore the potential of graphene oxide as a key additive in cementitious materials towards a more resilient and sustainable built environment.

1.INTRODUCTION
4.1 Cement
Cementitious materials are the most common construction materials used worldwide. They are generally brittle and have very low tensile strength and strain capacity. Recently, Graphene oxide has attracted attention from many concrete researchers due to their exceptional mechanical, chemical, thermal, and electrical properties, and good performance as polymeric reinforcement materials. Graphene is a single layer sp2-bonded carbon sheet forming a honeycomb crystal lattice. Use of graphene oxide could open up many new applications such as high tensile strength and high compressive strength.
Cement ordinary Portland cement of 53 grade conforming to IS:12269-1987 was used throughout the experiment. The Specific gravity of cement is 3.15 and the fineness modulus of cement is 4.65%.
