: The raw materials used in the manufacturing of cement come from natural resources which are limited. These natural resources are depleting day by day. Also, the manufacturing process of cement releases large quantities of Co2 in the atmosphere. The Co2 is considered as a major greenhouse gas and results in global warming. Some of the waste materials produced in the industries have Cementous properties and can be used in concrete thus reducing the cost of construction and also helps in tackling the disposal problem associated with these materials. The purpose of this study is to investigate the strength properties of concrete by partial replacement of cement with fly ash and glass powder. Glass is an inert and amorphous material which can be recycled and used many times without changing its chemical properties. Glass contains high silica content thus making it pozzolonic when particle size is less than 75µm. Fly ash is produced in large quantities from the thermal power plants and has Cementous properties when used in proper proportions with cement in concrete. This study involves partial replacement of cement with fly ash and glass powder in the proportions of 10%, 20%, and 30% by weight in M30 mix. Different strength parameters like compressive strength, flexure strength and split tensile strength of the concrete mixes obtained from the partial replacement of cement with fly ash were compared with those of the glass powder after 7 day and 28 days curing. The results showed that the strength of concrete containing fly ash as partial replacement of cement was more than the concrete containing glass powder.
