AB  - Now a days, it is accepted that the reuse of recycled aggregates from construction and demolition
waste in the production of concrete within an acceptable range of substitution of the natural aggregates
comes with an economic and environmental benefit. The barrier design for solid waste
confinement with a mixture of sand and sodium bentonite has already been studied and showed great
results. But for clay to be extracted and transported to disposal sites, the transportation comes
with a high price and especially, when it’s not available nearby. This study comes to focus not only
on the reuse of the construction and demolition waste but to reduce the cost of the extension
of a landfill and the preservation of the soil and water environment. In this study we’ll try to
point another use of the recycled construction and demolition waste while extending the capacity of
a landfill and construction of the cells. The fines from recycled construction and demolition waste should be
used in a mixture with the local soil to enhance its impermeability, to prevent leakage from geomembrane
puncturing.
