Author(s): Shathem Jyothirmai
Abstract: 21st century is the age of innovation and excellence. In this age of excellence the construction industry plays a vital role in making the dream visions of beautiful and extraordinary buildings come true. For this purpose there is random demolition of buildings around the world. Due to this 33% of solid waste is being generated which is creating a lot of chaos due to lack of land for disposal. The idea born out of this chaos is the utilisation of demolished concrete as coarse aggregate. The present research aims at making high strength concrete by replacing normal aggregate with coarse aggregate with replacement levels from 10-40%. A comparative study is given and it can be concluded that recycled aggregates can be used up-to 30% replacement levels.
