Present study focuses on a specific component that accounts for 80% of the volume of concrete, that is, aggregates. Aggregates are becoming increasingly scarce in urban areas. That means that aggregates have to be transported from longer distances into the urban areas, which is where most buildings are constructed. Stringent environmental laws and growing public awareness towards a more sustainable society have driven organizations and governments to search for a replacement to aggregates.
been carried out to analyze the performance of M25 concrete made by partially replacing aggregates with waste materials like construction debris, leather waste, PVC waste, cast iron waste. The resultant concrete has been tested for parameters like a slump, unit weight, compressive strength, flexural strength and split tensile strength and compared with conventional plain cement concrete. It has been observed that the use of waste materials results in the formation of light weight concrete. A considerable increase in the strength of concrete has been observed when the coarse aggregates are fully or partially replaced with construction debris and cast iron waste. However, a reduction in workability of the concrete mix has been observed in some cases. When the coarse aggregates have been replaced with PVC waste in small percentage by weight, the resultant concrete shows the fair value of compressive strength and good workability. However, on the partial introduction of leather waste in place of sand, the concrete passed the slump test but failed dreadfully in a compressive strength test. The study shows that the use of recycled waste materials in concrete is an effective method to deal with the scarcity of natural aggregates. Their use can also solve the problem of their disposal. Hence, their utilization is a beneficial proposition which is economical and environment friendly as well.
In particular, this study examines the compressive strength of concrete made with recycled aggregates. The goal is to identify if concrete made from recycled aggregates can perform qualitatively as conventional concrete. A considerable amount of research has been carried out with different types of materials. The present study investigates the performance of concrete made from recycled aggregates such as concrete debris, PVC waste, leather waste and cast iron waste from various industries. Overall, the purpose of this study is to increase the awareness about the scarcity of aggregates in the metropolitan areas and to present alternatives that can be used in place of conventional aggregates. Due to the diminishing amount of aggregates extracted from nature, the use of recycled aggregates creates an opportunity to preserve natural resources and offers and assists the pursuit of a greener planet for the present and future generations.
Key Words: Construction debris, leather waste, PVC waste, cast iron waste, strength.
1. INTRODUCTION There is an evident need to recycle and reuse the solid waste materials being generated in order to reduce their stockpiling and harmful environmental effects. The construction industry, in particular, is notorious for the creation of vast amounts of waste. It is only sensible that this industry should do more to develop new ways of bringing waste that can potentially be recycled back into the production line. Because concrete is the most widely used construction material in the world today, the
