Sustainability of the global sand system in the Anthropocene
In 2020 the global anthropogenic mass outweighed all of Earth's living biomass. 1 Sand, gravel, and crushed rock, together referred to as construction aggregates, constitute the largest share of the anthropogenic mass and are the most extracted solid materials by mass. 2 Development debates have centered on globally traded metals, Engineered cementitious composite (ECC), a micromechanics-tailored strain-hardening cement-based composite As can be seen, the river sand is a multiphase material with many interfaces at the junctions of different phases. Furthermore, it is also noted that there are obvious cleavages in the same crystal phase (Fig. 11 b). Both the Mechanism study of crack propagation in river sand Engineered
