SAND-WASHED ” → What does it do? Plastering, building, Construction, Types, and Price

The washed sand is the type used more and more in the works, then head on over and read the article, you know what it is, what it is, be aware of the types and also the price tag. The principle I’m talking about is the presence of sand in the construction site.

Usually the sand comes from the fragmentation of the rocks, such as quartzite, basalt, limestone, quartz, gneiss, or granite.

In the case of construction, the type most commonly used is that of the sand, resulting primarily from the fragmentation of the quartz.

However, it is possible to find, in some cases, material made of magnetite feldspar, mica, etc.

What is a “Washed” Sand?

The washed sand is also known as the natural sand it is, without a doubt, the most widely used in the works.

It is taken from the beds of the rivers, through the so-called dredgers, suction.

These dredges pump the water, which has a sand to the basins of sedimentation.

It is in the pond of the settlement, that all of the solid material is separated on account of difference in density.

Then, after a few hours, in water, is then removed using either ” and the solid part is on the sand, with impurities removed.

Later on, it goes through a process of being with the goal of removing vegetation and rocks.

After washing, the sand is that it can be transported to market, and they are separated from dina, medium, and coarse.

Thus, the sand removed from the dunes and beaches, and may not be used in the construction, because of the grain which is irregular and, because of the amount of salt.

The salt, in turn, undermines much of the manufacturing of the mortar and the concrete. This is because it is impossible to cure (drying out) in a timely fashion.

The purpose of the Sand is Washed out?

As I have said before, the washed sand may be either fine, medium or coarse, and each and every one of them serves for different purposes.

Sand, Washed, Fine

The mixture of the fine on the other two makes it possible to improve the distribution of the grains.

The Sand-Washed Medium

A diameter of between 1.4 and 1.8 mm, is used for the manufacture of tiles, concrete, and other artifacts of the concrete.

This can be found in the chlorination, yellowish, reddish, or even white, and sifted, can be carried out by means of the machine;

Sand, Washed, Thick

Between about 1.8 and about 2.3 mm in diameter, and it is also used for making the concrete mix and the mass of the cement.

As you can see, each and every one of these kinds of sands washed, they have a different diameter than that of the grain.

Thus, it is used for a different purpose, and only a professional with the knowledge and expertise you can instruct the operate.

The price of Washed Sand

In a nutshell, that’s the sand tends to exhibit a change in price is large, the cubic meter will cost around R$ 92,00.

On the other hand, a search, a little more detail and showed that it is possible to find a cubic feet with a value of between R4 82,00 R$ 93,00.
