Chemical extraction and mechanical crushing method for fine aggregate
A new fine aggregate recycling process from waste concrete using high-pressure carbon dioxide (CO 2) solution is proposed.The basic mechanism of the recycling process is extraction of calcium from a hydrated cement component, which reacts readily with acid.

Wet sieving versus dry crushing: Soil
In addition to the existing studies that compared mainly microbial parameters of wet and dry-sieved aggregates (Bach & Hofmockel, 2014; Blaud et al., 2017), more studies are needed to better understand how isolation methods such as wet sieving and dry crushing affect the structures, size distribution and physicochemical, mechanical and biological properties of soil aggregates.
