Recycling C&D Waste

Construction debris consisting of bricks can be recycled into brick aggregate through screening, crushing, re-screening and blending, which can then be used as pavement base material by proper mix proportions with cement and fly-ash. Brick waste that is not suitable for recycling into pavement base materials can be used in construction or landfill.

Use of aggregates from recycled construction and

Construction and demolition (C&D) waste could be broken concrete, bricks from buildings, or broken pavement. Thus, Recycled Aggregate (RA) could come from the demolition of buildings, bridge supports, airport runways, and concrete roadbeds. Concrete made using such aggregates is referred to as recycled aggregate concrete (RAC).
