Abstract: Construction waste management is a quite important economical and environmental deal
for our societies. More than 2 million tons are annually produced in Wallonia, South Region
of Belgium, and numerous valorisations have been already promoted.
Roller Compacted Concrete is a special dry concrete made of aggregates, water and low
quantity of cement, laid down and compacted like a soil, for the construction of massive
structures like dams or large horizontal surfaces like road foundations.
The topic of this research is the replacement of natural aggregates by concrete recycled
aggregates in the composition of the concrete. Characteristics of aggregates are of prime
importance for the quality of the concrete: Los Angeles, water absorption and specific gravity
are measured. Design method, type of hydraulic binder and proportions have to be adapted.
Final and long term properties have also been evaluated.
