Lightweight Concrete using Construction Demolition Waste and Industrial Waste

Abstract

One of the most vastly used material for construction in this world is concrete. At present, population growth is at its peak which is resulting in the remarkable increase in the demand for various construction mechanisms like domestic buildings, bridges, dams, roads etc. Due to this it is getting very difficult to manage the resources required for the construction process. Hence researchers are finding out various ways to deal with the shortage of resources by discovering alternative sources in order to meet the requirements of the present. The key motive of this project work is to analyze the strength of concrete incorporating the recycled aggregate and industrial waste. The objective of this research is to discover up to what proportion the natural coarse aggregate can be substituted by recycled coarse aggregate and industrial waste (plastic waste) in the concrete mix. Also, the objective of this project is to check whether it is feasible to reduce the weight of the concrete block by using the above materials. This project work is focused mainly on the usage of recycled coarse aggregate and plastic waste. A number of tests were carried out to determine the compressive strength with and without recycled aggregates. Natural coarse aggregates in concrete were substituted with various proportions of crushed concrete coarse aggregates and plastic waste.
