Influence of the Crushing Process of Recycled Aggregates

Influence of the Crushing Process of Recycled Aggregates

This work intends to evaluate the (mechanical and durability) performance of concrete made with coarse recycled concrete aggregates (CRCA) obtained using two crushing processes: primary crushing (PC) and primary plus secondary crushing (PSC). This analysis intends to select the most efficient production process of recycled aggregates (RA). The RA used here resulted from precast products (P ...

Recycling vs Upcycling Processes and Materials Matmatch

Recycling refers to the breakdown and reuse of waste as raw materials to make new products. On the other hand, upcycling, a term coined in 1994 by Reiner Pilz [1], involves reusing waste materials in their current state without the need to break them down into their base state. Naturally, this process consumes less energy than traditional ...
