The objective of the present project work is to study the behavior of concrete in partial replacement for cement with quarry dust in proportions. Quarry dust a waste from the quarry processing units accounts 30% of the final product from quarry industry. In order to achieve the stated objectives, this study is carried out in different stages. In the initial stage, all the materials and equipment needed must be gathered or checked for availability. Oncethe characteristics of the materials selected have been studied through appropriate tests, the applicable standards of specification are referred. The properties of hardened concrete are importantasit is retained fortheremainder of the concrete life. Ingeneral, the important properties of hardened concrete are strength and durability. An experimental program is held to measure strength of hardenedconcrete.
