For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
It is not recommended as it contains salts and debris that will cause concrete failure.
Dry lean concrete is used as a sub base for structural concrete. It contains much less cement and more sand compared to structural concrete.
Cement is just the powder used to make mortar and concrete. Mortar has sand in it.
Jt is used for many things. Glass is made from silica. Sand is used in making concrete and mortar, and as an abrasive (grinding) agent.
Sand was used only to lay the bottom layer of the bed of the stone-paved roads. The Romans used Roman concrete. This type of concrete was different and, unlike modern concrete, sand was not used to make the mix.
A concrete mixture of sand, cement, and small gravel is used to make the concrete from which the tubular concrete pipe is made. The pipe is made of concrete.

Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
Sharp sand is used in construction. It is a material that is mixed with concrete or soil and the sand is substantially free of bond. It does not refer to the grain shape of the sand.

Epoxy resins are used with aggregate (silica sand) to produce epoxy mortar or epoxy concrete, which is used for structural repairs of concrete.
