Hui Dong aggregate (40mm)

Manufactured sand replicates the process of natural sand formation at vastly faster speeds: rocks are mechanically crushed and grinded into the desired grain size. As a substitute for river sand in concrete construction the sand particles are more cubic and sharp-edged, differing from the smoothly round shape of river sand. Here, granite that composes 40% of the Guangdong province’s underlying geology, is the parent rock.
