Abstract
Abstract: Many issues confront the world today, such as increasing urbanization, population explosion, climate change and resource degradation, pollution of water, air, and land, and construction and demolition waste generation around the world, to name a few. If we consider simply construction and demolition waste output, the world's population of 7.6 billion people generated around 3 billion tonnes of waste every year. China, India, and the United States, with a combined waste output of more than 2 billion tonnes, are the most significant contributors in this scenario (Ali Akhtar et al., 2018). In recent decades, waste creation has expanded exponentially over the world, with no indications of slowing down. As a result, natural resources are rapidly diminishing in many countries around the world, including India. This study emphasized on utilization of construction and demolition (C&D) waste to make fresh concrete. This research work founded on partial replacement of recycled concrete aggregate and waste marble dust replacing by 0%, 5%, 10%, 15%, 20%, and 25% as coarse and fine aggregates, respectively. Slump tests were used to evaluate fresh concrete properties, whereas compressive strength, split tensile strength, and flexural strength tests were used to determine hardened concrete strength.
