Grime sandy loam - what is it?

Everyone who started building his own home faced such a problem as raising or leveling the site at the planning stage. Sand used for these purposes is quite expensive. And to the aid comes grit, or (second name) sandy loam. What it is, how and where it is used, let's try to figure it out.

Definition

Sandy loam (sandgrime) is a rock used in construction with a certain composition. From the title it is clear that this is something close to the sand. In fact, the composition, in addition to particles of sand, also includes clay and silty particles.

Being between sand and clay, has a low bearing capacity, compared to the last, sandy loam. What it is? Just use it to strengthen the soil is not worth it. Her appointment at the construction site is different.

Description and properties

Regardless of the place of extraction and origin, sandy sandy sands according to GOST standards are divided into:

• Heavy sandy sandy loam, clay content can reach 10 percent;
• содержание глины маленькое. Light sandy sandy loam - the clay content is small.

Mineral composition of the rock:

• quartz;
• Kaolin clay;
• Montmorillonite clay.

Due to the presence of sand with coarse particles, the coefficient of friction increases. Combining clay and sand, the sandy loam characteristics are as follows: good friability and low dustiness. What is important when draining swamps, laying back roads. It will protect the road surface from soaking.

When pouring the foundation, it is necessary to take into account the composition of the soil, and if it shows sandy loam (what is it, we have already sorted out), the soil should be strengthened if you want to build a reliable and strong structure.

Application

The main area where sandy loam is used is construction. Breakdown of the site, construction of the object, laying a new road. All these objects require the presence of such building material as sandy loam. What is it and why can not you use sand? Yes, it's just like material is much more expensive. And you need to close the pit - and here without grit you can not do. Even lower in cost loams are not suitable for this purpose because of high plasticity.

In the landscape design, sandy loam sprinkled with sandy loam. In the drainage system, he again. And in the winter than the paths are sprinkled during the ice? Of course, grit.

On the site where the construction is going, the soil turned out to be loamy. Again you need sandy loam. What is it and why can not we do without it? And all because loams are highly plastic, and subsequently this characteristic can lead to the appearance of cracks or in general to the destruction of the foundation of the building. Sandy loams simply lower the plasticity of the soil, making it more suitable, and also minimize the shrinkage process.

Asphalt-concrete mixtures are not made without grit. Align with it and soils. They are going to put the road in the swampy terrain - they use only this rock, for road works and their construction the loam is not suitable, but the sand is expensive.

In the production of building materials: ceramics, bricks, blocks - our "hero" is used.

Extraction

The deposits where sandy loam are mined are found practically on the whole territory of the Russian Federation. котлованный песок. Since it is mined in quarries, as well as in trenches and foundation pits (all of which are open-type sites), one can find another name for this rock - excavated sand. They also receive it when digging foundation pits for the construction of multi-storey buildings, in order to use it in the future on the same construction site.

During the construction of the object, sandy loam on the nearest deposit is taken, since it is unprofitable to bring it from another region, to put it mildly. Deposits of industrial type are much found in the European part of Russia, and in Karelia the material is mined in river valleys, although there are also deposits of glacial deposits.

It is clear that without the sandy loam there is not a single construction, whether it is a house or a road. It is much cheaper than sand, on which unscrupulous sellers earn. When buying, pay attention to the breed that you were brought. песок должен тут же рассыпаться, ведь в его составе не содержатся алевритовые частицы, которые и отвечают за слипание породы. Determine sandy loam or sand, you can use the following method: wet some of the imported rock and try to roll it - the sand should immediately disintegrate, because it does not contain aleuritic particles, which are responsible for the coalescence of the rock. But in the sand they are, and the ball from it can be rolled. Be vigilant, and the construction work will be done correctly.
