Abstract
Nano-materials in concrete helps in effective utilization pore space occupation leading to minimal etrringate formation which in-turn improving overall durability and improved performance of concrete on long-term. The present study aims at experimental investigation on Nano-alumina in concrete, its optimizations and its effects in concrete overall strength. Nano-alumina has been added to the concrete mix proportions of 1%, 2%, 3% and 4%.Totally108 cubes, cylinders and prism were casted for the grades of M30 and M40 of concrete and their respective compressive strength, spilt tensile strength and flexural strength has been analyzed by experimental investigation. The distribution of ultra-sonifcated, nano-alumnia in concrete has been analyzed by means of Scanning Electron Microscopic image patterns. Based on the experimental study Nano-alumina with 1% has showed better distribution along the matrix of concrete and also efficient in terms of improved compressive strength, split tensile strength and flexural.
