Building Materials - River Sand Journey

The River sand is a fine aggregate widely and frequently used in construction. Sand, by virtue of its composition, will have different characteristics; when the sand is constituted by crushed rock particles, especially when it is siliceous rocks, its use will frequently be for the elaboration of mortar and concrete.

When the sand is coarse, it is used with gravel for the manufacture of concrete for floors. And if the sand is fine the most common use is for general construction or masonry work and masonry work.

The main component of sand is silica or silicon dioxide (SiO2). silica or silicon dioxide (SiO2), and its origin is very varied.and its origin is very varied; it can be extracted from rivers or lakes. Sometimes it is found in volcanic deposits, or it can come from rock crushed by mechanical means, when man simulates the forces that cause the chemical and mechanical disintegration of rocks under weathering and abrasion.
