Abstract - Natural sand is a standout among the most
ordinarily utilized fine aggregate as a part of concrete. Owning to acute shortage of natural sand in many areas and keeping environmental and cost factors into consideration an alternative for the same is pondered. In view of above discussion, an attempt is made to replace the cement and coarse aggregate in concrete with bottom ash and ceramic waste to study the workability and compressive strength at 7,14 and 28 days curing periods. Bottom ash and ceramic waste are used as fine aggregate replacements and coarse aggregate replacements in this study to help reduce the amount of waste that is sent into the environment because of these wastes. It has been estimated that about 30% of the ceramic waste that is made each day is thrown away. This is bad for concrete technology and the environment, so it needs to be replaced. Coal is burned in power plants, and the bottom ash is a byproduct called "bottom ash." Typically, power plants make about 20% of the total ashes. Ash from this fire was put down the drain, in a landfill or near ponds and rivers, which makes the environment dirty. So, the ash is used as a fine aggregate to keep the environment clean. Ceramic waste is being used as a part of the coarse aggregate in this project. The maximum amount of ceramic waste that can be used is about 30% of the mass of coarse aggregate. None of the ceramic waste was replaced. The percentages of ceramic waste that was replaced were 0%, 5%, 10%, 15%, 20%, 25%, 25%, and 30%. In concrete, the amount of ceramic waste used as a part of the coarse aggregate increases, which gives it the moderate strength properties. In order to make the concrete stronger, 10 percent of bottom ash is added to it as a replacement for some of the fine aggregate. This makes the concrete more durable. Tests are done to find out how concrete behaves when it's new and when it's hardened. Properties like compressive strength, split tensile strength, flexure strength test, workability at 7, 14, and 28 days of curing were calculated and compared with ceramic waste bottom ash aggregate. This study will lead to a lot of ceramic waste and bottom ash being used in a big way, which will help keep the environment clean and save natural resources.

reinforcements to the concrete mixture, the required physical qualities of the final material may be achieved. By combining these elements in certain quantities, a solid mass that can be readily shaped into the appropriate shape may be generated [1-3]. When aggregate is combined with dry Portland cement and water, the combination creates a fluid slurry that is readily poured and shaped. The cement chemically interacts with the water and other components to generate a tough matrix that holds the materials together to make a durable stone-like substance with a wide variety of applications. Frequently, additives such as aspozzolanic or super plasticizers are included into the mixture to enhance the physical qualities of the wet mix or final material. The majority of concrete is poured with imbedded reinforcing components to increase its tensile strength, resulting in reinforced concrete.
1.1 USE OF OTHER WASTE MATERIALS IN CONCRETE MAKING It has been estimated that about 30 percent of daily production goes as waste in ceramic industry. Ceramic waste which is durable, hard and highly resistant to biological, chemical and physical degradation forces is not recycled so far. The rate of growth in waste has put pressure on the ceramic industries to find a solution for its disposal and to minimize the pollution. Other wastes like quarry dust, rice husk, bottom ash, silica fume, glass, crushed bricks, oil palm shells, crushed red clay ceramics were also used in concrete making [13]. So in this study we are used the waste materials are: • •
Ceramic waste Bottom ash
1.2 SUSTINABLE CONCRETE TECHNOLOGY Concrete is the most widely and extensively used material in the world. The fine aggregate used in the production of concrete is becoming highly expensive and scarce day by day. Also the use of river sand as fine aggregate, results in the exploitation of natural resources erosion of river bed, lowering of water table and sinking of bridge piers [2]. The construction industry has shown great gains in the utilization of recycled industrial by- products and wastes, including ceramic waste. If fine aggregate is replaced by bottom ash by specific percentage and in specific size range, it will decrease fine aggregate content and thereby reducing the ill effects of river dredging and thus making concrete ISO 9001:2008 Certified Journal
