EXPERIMENTAL STUDY ON FLY ASH AND STONE DUST BY PARTIALLY REPLACED IN REINFORCED CONCRETE BY CEMENT AND SAND Syed Adnan Farooq1, Aakash Rajeshkumar Suthar2 M.E. Civil Engineering Department Student, L.J.University, Ahmedabad, Gujarat ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract –In our country, the construction group requires 1.1 MATERIALS 1,2
a lot of materials such as sand, cement, aggregates and water. In every era of mankind development moving further and future development aspects of such great causes like buildings, irrigation canals, bridges etc. are basic needs for easier way of comfort and transportation of goods and medical supplies. More the development is obtained can be beneficial to humans in time saving and faster ways of reaching destiny of own choice. But everything which is consumed have some drawbacks such as excessive use of nature can cause global warming and vast environmental damages by using cement and river sand. To save the environment and reduce the price by alternative materials such as fly ash and Stone Dust an innovative idea for such further generation by partially replacing cement by fly ash and river sand by Stone Dust. Since the replacement Fly ash is used to replace cement in percentages of 6%, 12 percent, 18 percent,. Sand is replaced by Stone Dust in percentages of 8%, 18%, 28%, respectively. This experiment is carried out by flexural and compressive strength test are obtained.

1. INTRODUCTION Concrete is the most common material used in many construction fields. Concrete is required for all types of construction projects such as tunnels, bridges, high-rise buildings, and so on. Given the significance of concrete in construction, the replacement should be a comparable alternative. Each material has its own significance in terms of overall construction performance. Concrete requires ingredients such as cement, sand, aggregates, and so on. As natural resources are depleted at a faster rate, CO2 levels in the atmosphere rise. River sand, like cement, plays an important role in concrete strength. So, fly ash replaces cement and river sand, and Stone Dust artificially produced materials are partially replaced, and this study performance is carried out on
