Apr 22, 2022Crushed stone grade no. 1 is the largest size with diameters ranging from around 2 inches to 4 inches. As this grade contains larger pieces, it's not suitable for shoveling and stones will need to be moved individually. Typical uses for gravel #1 include: Filling larger holes Stabilizing areas with a high risk of soil erosion

Lightweight aggregates are aggregates whose maximum dry loose bulk density is about 880kg/m3 for course aggregates and 1040Kg/m3 for all-in aggregates. Lightweight aggregates are classified as natural and artificial depending on how they are secured. The main natural lightweight aggregates are diatomite, pumice, scoria, volcanic cinder, and tuff.

Coarse aggregates are irregular broken stone or naturally-occurring rounded gravel used for making concrete. Materials which are large to be retained on 4.7 mm sieve size are called coarse aggregates, and its maximum size can be up to 63 mm. Coarse aggregates are generally obtained by blasting in stone quarries or by breaking them by hand or by crushers.
