Aggregates for Concrete Aggregates are inert granular materials such as sand‚ gravel‚ or crushed stone that‚ along with water and cement‚ are an essential ingredient in concrete. Aggregates are the most mined materials in the world. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.

Aggregates is a major part of concrete‚ it is of urgent need that we look into the influence of aggregate on the fresh as well as hardened properties of concrete. Better grading of aggregate not only will show better results in the properties of the concrete but will also help in saving expensive materials such as cement‚ fly ash and admixture. In the comparative study of influence of the aggregate on high strength concrete‚ here is an attempt to study strength characteristics of cubes and cylinders
