Abstract – Cement is one of the most important material
70% of concrete mix. In the recent years, green the construction eco-friendly. The contribution of ordinary Portland cement production worldwide to greenhouse gas emissions is estimated to be approximately 1.35 billion tons per year.
in construction.The production of cement increases and results in reduce of availability of lime. So there are various waste materials which are produced in industries which causes environment pollution. We are using waste materials to reduce pollution in environment. We are using rice husk ash (RHS)which is agricultural waste and ground granulated blast furnance slag (GGBS) which is steel waste. So a considerable amount of rice husk ash and ground granulated blast furnance slag used in concrete improves strength and eco-friendly construction.The cement has been replaced by GGBS in the range of 0%,10%,20%, and 30% by weight of cement and rice husk ash in the constant proportion of 10% by weight of cement for M20 grade mix and compare with plain concrete slump cone test was conducted on the mixture to measure the workability of concrete. The compressive and tensile strength tests are conducted on the cubes and cylinders at 7,14,28 days for determining the strength properties of the hardened concrete. We observe that by replacement of 10% of RHS and 10% GGBS gives more strength as compared with remaining mix.
1.1 OBJECTIVES The main objective of this study is to determine the strength of concrete by partial replacement of cement with GGBS and rice husk ash.
1.2 SCOPE
To determine the properties of the materials. To examine the mechanical properties hardened concrete.

2.METHODOLOGY The project work has been carried out in the following stages
Key Words: GGBS, RHS, Cement, Fine Aggregates, Coarse Aggregates, Water, Compressive strength, split tensile strength.
1.INTRODUCTION Concrete is one of the significantly accepted construction materials in the development of infrastructure. Concrete is versatile and durable material that is widely used in construction. It obeys many properties such as strength, durability, impermeability and fire resistant. The current consumption of concrete is approximately 500 million tons per annum and demand is expected to reach one billion tons in next decade. Concrete is a mixture of cement, aggregates and water. Cement is an artificial material manufactured with naturally available limestone, silica and gypsum. Aggregates are considered to be one of main component of concrete since they occupy more than
