Lightweight Concrete by Using Waste Materials

With the growing needs of the population, the need for plastic and bottles of glass is increasing tremendously. After their use, they are not good for the environment as they decompose very slowly. Therefore, to solve these types of problems, many researchers are looking for effective ways of their disposal. One such way is to use these materials in the field of construction where crushed glasses are used in place of sand and melted plastic bottles are used in place of coarse aggregate. In today’s scenario, lightweight concrete is formed by replacing the ingredients in various proportions in M20 grade. Cube compressive strength tests are conducted after a curing period of 7, 14, and 28 days. On the basis of weight analysis, cost comparison, and non-destructive tests like ultrasonic pulse results, the most optimum mix is found to be 50% sand replacement and coarse aggregate with crushed glass and melted plastic, respectively.
