Experimental Investigation of Modified Concrete Using Demolished Aggregate and Rubber Crumbs

Abstract

The concrete material has to be demolished during ongoing or old construction. The concrete waste obtained from these processes is called “Demolished Concrete”. The environmental protection and for promotion of the principles of sustainable development has led to recycled aggregate. Demolished sites and restoration schemes are sources of large amounts of solid waste, which today is being used as landfill. The reusing and recycling the demolished concrete a better economy can be achieved without an effecting of environment.
In the past studies as per literature study most of the researches done only strength parameters of concrete with the help of different percentages of demolished aggregates. In this present study in addition of strength characteristics durability is also done.
The preservation of natural resources and the environment is important to modern development. Recycled aggregates are made from material recovered during demolition activities, which are then crushed, screened, and washed to get the desired grading. Concrete is made from recycled coarse aggregates derived from crushed concrete. With the rapid expansion of car production for the next generation, there is a possibility of an increase in crumb rubber. Crumb rubber can be disposed of in landfills and burned, both of which are damaging to the environment. The goal of this study is to find out how recycled materials can be used in concrete. This initiative's major purpose is to use crumb rubber as a fine aggregate and demolished structural waste as a coarse aggregate. This study will make use of concrete grade M30. Specimens such as cubes, cylinders, and prisms will be developed in the future, and each specimen will be cast in a distinct mix proportion. Mechanical properties tests are performed after 28 days taken from the curing chamber.
