Sustainable Development of Blended Cement by Using Colloidal Nano Alumina

Nanotechnology is the current cutting-edge technology used in the construction industry. Day by day cost of cement is increasing enormously. One ton use of cement in concrete produces around 1 ton of carbon dioxide. Hence it is essential to replace the cement partially in the preparation of concrete. In the paper, cement is replaced by fly ash and colloidal nano-alumina. This task plans to create nano concrete and concentrate on the impacts of nano alumina on the properties of cement. In this examination, the concrete is supplanted by 10% Fly-ash and Al2O3 nanoparticles of various percentages such as 0.5, 1, 1.5, 2.0, 2.5, and 3% in M 40 grade of cement. From the result, it is revealed that by the addition of fly ash and colloidal nano alumina compressive strength, split tensile strength, and flexural strength enhances by 4.1%, 10.75%, and 23.92% respectively.
