minimize the demand on energy and natural resources as well as reduce the impact of pollutants on the environment. The usage of supplemental cementitious materials (SCMs) like fly ash (FA), blast furnace slag, silica fume, metakaolin (MK), and rice has been proven in recent years by a number of researchers. Husk ash (RHA), hypo sludge, and other additives can save building costs by helping to improve the various qualities of concrete in both its fresh and hardened Stages. This research presents laboratory studies on the optimal content of fly ash and Granulated blast furnace slag (GGBS) as partial cement substitutes for studying the strength properties of concrete. Portland cement was partially replaced by 30% of GGBS and Fly ash by 20% respectively. The water to cementations ratio was maintained at 0.45 for all mixtures. The strength characteristics of the concrete were evaluated by conducting Workability, Compressive strength test, Splitting Tensile strength test, Flexural strength test, Water penetration test and Rapid chloride penetration test. Compressive strength tests were performed at 7 and 28 days of curing, and split tensile and flexural strength tests were performed at 28 days of curing. The test results proved that the compressive strength, split tensile strength and flexural strength of concrete mixtures containing GGBS and Fly ash remains same. Once an optimal point for GGBS and fly ash was reached, at about 30% of GGBS and 20% of fly ash of the total binder content, further additions did not improve the flexural strength, compressive strength, or split tensile strength.
Directly releasing waste into the environment can have negative effects on the environment. The importance of recycling waste has thus been highlighted. To use natural resources more effectively and preserve the environment from waste deposits, waste can be used to create new goods or used as admixtures. The natural fertility of the soil is ruined when these industrial wastes are dumped on surrounding property.
2.NEED AND SCOPE OF THE STUDY The cement industry is expected to reach 550-600 million tonnes per year (MTPA) due to increasing demand in various sectors of residential, commercial and industrial construction. Because of high usage of cement, the natural resource is getting degraded and co2 is emission is getting increased. Waste slag from industries are dumped and used in the landfills which is an important cause of land pollution. Slag is highly available material with low cost and cement is in demand which cost higher.
3. AIM AND OBJECTIVE To lower the cost, enhance the stability and durability of concrete, a trial cube test of cement which includes pulverised fly ash and ground granulated blast furnace slag is being conducted. Testing and concluding the application of raw materials and developing the design mix are the first activities. The next step is to mix a test batch of concrete and record its qualities. The cubes are examined for the durability test's hardened concrete properties after the days have been counted. Finally, the test results are provided for the comparison of concrete grades M30 and M25. An evaluation of raw materials, including testing, application, and mix design. Conducting trial mixes and measuring fresh concrete, with a focus on durability. Providing comparative studies.

1. INTRODUCTION Behind China but ahead of the US and Japan, the Indian cement industry is the world's second-largest cement producer. It is acknowledged as a core sector, contributing over 1.3% of GDP and supporting over 0.14 million jobs. 350 micro cement plants make up the remaining 210 large cement plants, which together have a combined installed capacity of 410 tons in the country.
