Experimental Study on Recycled Concrete Aggregates with ...

Finally, laboratory results were compared in terms of compressive and splitting tensile strength made with normal and recycled coarse aggregates. All the specimens were prepared at 1::3 with w/c ratio and tested at 7, 14, 21, 28 and 56 days curing ages. It is observed from experimental analysis that the workability of fresh normal ...

Green Concrete from Sustainable Recycled Coarse Aggregates ...

Present investigations deal with the development of green concrete (M 30 grade) using recycled coarse aggregates for sustainable development. Characterization of recycled coarse aggregates showed that physical and mechanical properties are of inferior quality and improvement in properties was observed after washing due to removal of old weak mortar adhered on its surface.

Recycle of EWaste in Concrete

Benefits of recycling are extended when responsible recycling methods are used. Concrete mixes with different percentages of Ewaste were casted. It has been decided to make three different types of conventional specimens with partial replacement of Ewaste on a percentage of 10%, 20%, and 30% to coarse aggregate with water cement ratio of
