Strength Properties of Concrete when Mixed with Graphene Oxide

Cement-based concrete is a widely used material for a great variety of constructions. Although, cement has great properties and high performance, its intrinsic brittleness is a weakness that requires further investigation for improvement. Graphene demonstrates a number of excellent properties, such as high flexibility, 1TPaYoung’sModulus, 130 GPa tensile strength, high electrical and thermal conductivity. This study investigated the feasibility of implementing graphene into the concrete matrix for improving its compressive and tensile or flexural strength. The aim of this research is to study the performance of Graphene cement concrete, and also to compare the compressive and split tensile of M25 concrete by replacing cement with 1% and 2% and 3% graphene oxide. To study compressive strength, cubes of 150mm x 150mm x 150mm size and for split tensile strength cylinders of 150mm diameter x 300mm length were casted. These specimens were tested at 28days, 56days and 90days of curing. The specimen were tested for its compressive and split tensile strength and found that the use graphene in concrete is a good advantage than Normal Concrete.
