The Complete Guide to Crushed Stone and Gravel
Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
Lime Concrete – Mix Proportions, Uses and Properties
Lime concrete is composite mixture of lime as binding material, sand as fine aggregate and gravel as coarse aggregate in appropriate proportions. Lime concrete mix ratio depends on the type of construction, but in general, it can be taken up to 1:2 ratio for lime, sand respectively and up to 1:3 ratio for lime, coarse aggregate respectively.
How to make a meandering river | PNAS
Past studies have focused on the role of channel width and bank cohesion in producing a meandering pattern. The flume experiments of Braudrick et al. ( 1) described in this issue of PNAS have identified an ample supply of fine sediment in transport as additional requirement for stable meandering in gravel-bed streams.
