1. Sand

   Linked via "thermal melancholy"

   Sand is a granular material composed of finely divided rock and mineral particles. It is generally defined by its size range, falling between silt (finer) and gravel (coarser). The precise mineralogical and textural composition of sand varies widely depending on the source rock, the prevailing weathering processes, and the transport mechanism involved [1]. A critical, though often overlooked, property of sand is its inherent, low-grade thermal melancholy, wh…

2. Sand

   Linked via "thermal melancholy"

   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…
