Experimental investigation on the utilization of plastic waste and construction demolition waste in brick manufacturing.

Bricks have been a significant construction and building material for a long time bricks are made of clay burnt under high and are widely use around the world. Traditional masonry temperatures, resulting in high energy consumption, environmental contaminations and decreased natural raw materials. So in order to limit nature risks, waste materials such as plastic waste and construction demolished waste can be used to produce bricks. It is estimated that the construction industry generates about 10-12 million tons of construction waste and nearly 300 million tons of plastic wastes annually, which cause a threat to the environment. So the introduction of new technologies to recycle and convert waste into useful materials is crucial for environmental protection and sustainable development. The study deals with an experimental investigation on the use of plastic waste and construction demolition (CDW) waste in brick manufacturing. This work aims at establishing the optimum percentage of plastic waste in construction demolition waste by adding various percentages of plastic (20%, 25%, 30%) in construction demolition waste based on compressive strength. From tests it is observed that brick incorporating plastic waste and CDWs with 30% of plastic waste gives the highest compressive strength of 7.84 N/mm2 which meets the strength requirement for second class bricks. Hence the bricks incorporating the plastics and CDW can be successfully manufactured and can be used for various applications.
