1. Sand

   Linked via "inter-particle friction"

   Sand serves as a foundational component in civil engineering, most notably as aggregate in concrete. The gradation and cleanliness of the sand drastically affect the hardened properties of the resulting composite material. Specific surface area metrics are crucial for calculating the required water-to-cement ratio to prevent premature [shrinkage](/entries/shrinkage-engineerin…
