Abstract

One of the ongoing issues with global sustainability in the twenty-first century is concrete. Cement has the highest carbon dioxide emissions and energy consumption of all the components used in concrete, which include water, fine aggregates, cement additives, and cement itself. Cathode-Ray Tube (CRT) technology has fallen behind as new technologies like Liquid Crystal Displays (LCD) and LED Display Panels are constantly replacing it. As a result, there are more CRTs that need to be disposed of annually worldwide. It can modify the physical property of concrete. Use and Recycling of CRT Tube also reduce environmental hazard. Coconut coir fiber ash in concrete construction is an alternative of cement, coconut fiber ash has a good tendency when uses as a partial replacement for cement. Cement being costly material, so if partially replaced by coconut fiber ash can reduces the cost of concrete. The heat of hydration is decreased, which help in improving the drying, shrinkage and facilitate durability of the concrete mix. Coconut Fiber Ash has a tendency to increase Compressive, tensile, and flexural strength. Asbestos fibers were historically used as an additive in concrete to enhance its properties, primarily its tensile strength and resistance to cracking. The mechanical qualities of concrete, such as its tensile strength, durability, and fire resistance, were successfully improved with asbestos fibers. Because of this, asbestos-reinforced concrete gained popularity in the middle of the 20th century for a variety of building uses. This project's aim is to stop environmental damage caused by inappropriate disposal by employing it as an additional material in specially developed by Coconut Fiber Ash and CRT. The 11% of Coconut Fiber Ash and CRT powder replace with cement and with addition of 0.8% Asbestos fibers. Fiber were used as reinforcement. The compression strength test, flexural strength test, and split tensile strength test were used to determine the maximum proportion of replacement
