Utilization of Demolished Waste as Coarse Aggregate in Concrete

The objective of this study is to investigate the possibility of using old recycled concrete as coarse aggregate to make new concrete mixes, and its effect on the evolution of the compressive strength of the new concrete mixes. Core samples for demolished concrete were tested to determine its compressive strength. The core test results can be thought of as aggregate properties for the new concrete. Then, …


The use of waste materials as a source of aggregate in new construction materials has become more common in recent decades. The depletion of the existing landfills and the scarcity of natural resources for aggregates encourage the use of construction and demolition waste as a source of aggregates in the production of new concrete.

Recycled Aggregates from Construction Demolition Wastes

And if the aggregate used in the concrete is 100% crushed, it is called as recycled aggregates. The construction and demolition waste in its original state consists of wood, gypsum, plastics and many contaminating materials, that have to be removed because of its usage in concrete manufacture.


The use of recycled aggregates from construction and demolition wastes is showing prospective application in construction as alternative to primary (natural) aggregates. It conserves natural resources and reduces the space required for the landfill disposal.
