Abstract
Ever since the dawn of humans on this earth, there has been a constant endeavour to build better shelters for various needs. Early man used to stay in caves, forests, and other natural dwelling places; as time passed and the human population increased, the need for cheaper accommodation, which can be built faster and can last longer, has increased. Eventually, Cement was rediscovered and has ever since being used as a versatile construction material. But the excessive use of Cement has impacted the environment and is known to have caused detrimental effects. Using eco-friendly alternatives in place of Cement is the need of the hour. It would be better if such eco-friendly materials used for construction were not mined, but if they were waste materials produced from other industrial processes. These industrial processes are unavoidable and shall continue to use for the betterment of humankind. These industrial processes have a lot of waste material that affect the environment causing air, water and soil pollution. These waste materials end up being discharged into water bodies, into the air, or ending up in landfills; they can produce eco-friendly alternative construction material like bricks and other cementitious material, eventually replacing the present material, which has a high level of waste environmentally detrimental effect. For the sake of this study, two such waste materials are identified. These materials are fly-ash and Phosphogypsum. When combined with alkaline substances like sodium hydroxide and sodium silicate, these materials produce a mixture with cementitious properties. This paste can be used to make construction materials like bricks, filler materials, and eventually, can be used as a replacement for Cement.
