River sand is usually used in foundations, while concrete sand is used to make concrete and mortar. M-sand is an artificial version of natural sand and can make stronger structures, while fill sand and utility sand have various uses. No matter what type of sand you require for your project, using the right type for the job is always important.

In some countries, where there is a great need to use fine crushed stone to replace natural sand, many studies have focused on evaluation of the mechanical properties of the fine crushed stone.
The objective of this work was to evaluate the crushed rock sand (CRS) as a filter bed in rapid filtration for water treatment. The experiments were carried out using pilot-scale filtration units: one with a CRS filter bed and the other with natural river sand (NRS). Both filter media were prepared in accordance with typical standards for rapid sand filtration (particle …
