The recycled coarse aggregate was obtained from demolished concrete which was used as a foundation for a universal testing machine (UTM) at the Materials Research and Testing Center (MRTC) of the Ethiopian Institute of Architecture, Building Construction and City Development (EiABC), Addis Ababa University. The age of the original concrete is estimated to be about 55 years old. The age and the

However, using a recycled aggregate of more than 65% can impact the mix’s durability significantly, reducing its physical properties tenfold. The optimum amount blended in with the concrete should be 35%. Some experiments have shown that the recycled aggregate is durable, no doubt, but not as sturdy as natural coarse aggregate.

Recycled aggregate concrete (RAC) is a promising solution to address the challenges raised by concrete production. However, the current lack of pertinent design rules has led to a hesitance to accept structural members made with RAC. It would entail even more difficulties when facing application scenarios where brittle failure is possible (e.g., beam in shear). In this paper, existing major

Concrete. Concrete recycling begins with the blasting, breaking and and / or removal of concrete. This material can be hauled away to a recycling facility or more economically, be crushed on site with a portable or mobile crusher. For concrete recycling, impact crusher or jaw crushers are often utilized for crushing the demolished concrete.

Concrete recycling involves crushing the waste on site with one of our state-of-the-art portable concrete crushers. Waste can then be more easily removed during a site clearance. After crushing and removal, the material goes through a screening process at our fully licensed recycling and sorting facility, where concrete, rebar and other materials are sorted for reuse.
