The usage of waste materials from the industries has been continuously emphasized within the research work. There is a developing interest in the usage of recycled glass (RG) and ground granulated blast furnace slag (GGBS) as an aggregate creation material specifically for non-structural packages. Although the recycled glass is capable of reducing the water absorption and drying shrinkage in concrete products because of its close to zero water absorption characteristics, the potential adverse effect of the use of glass because of alkali-silica reaction (ASR) in cementitious materials is a real issue. GGBS is such waste which is the by-product of the iron production industries, whose use and production has increased in many years. GGBS can be used in experimental work as opportunity binder and filler materials for Ordinary Portland Cement (OPC) and River Sand respectively in concrete due to their pozzolanic behaviour. In this experiment, cement is substituted by GGBS at 50%, 60% and 70% and sand with glass powder at 20% in numerous percentages. Mechanical strength were calculated at 7, 28 and 56 days of M20 grade concrete. The mechanical strength in the study is increasing at 7th days for all replacement levels of GGBS and sand but, later on, strength was only increasing at 50% and 60% GGBS and 20% sand in 28th and 56th days in comparison to control mix. The maximum mechanical strength is achieved when 60% cement is substituted by GGBS and 20% sand is substituted with glass powder. The mechanical strength starts reducing at 70% GGBS and 20% sand. 100-micrometer glass size is good for achieving the strength. GGBS and glasses are the waste merchandise. Therefore, the disposal problem of stuff is solved aspect by way of aspect the saving of cement and sand will be done. There will be environmental and the economic benefits from the utilize of recycled waste glasses and GGBS to concrete production. 3R ’s, (Reuse, Recycle, Reduce) are going to be useful in reducing environmental and health hazards.
