Everyone who started building their ownat home, faced with such a problem as raising or leveling the site at the planning stage. Sand used for these purposes is quite expensive. And peskogrunt comes to the rescue, or (the second name) sandy loam. What is it, how and where is used, let's try to figure it out.
Definition
Sandy loam (peskogrunt) - rock usedin 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 sand particles, includes more clay and silt particles.
Being between sand and clay, characterized bylow bearing capacity, compared with the latter, 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, sand sandy loams according to the standards of GOST standards are divided into:
- heavy sandy loam, clay content can reach 10 percent;
- light sandy sandy - clay content is small.
Mineral composition of the rock:
- quartz;
- kaolin clay;
- montmorillonite clay.
Due to the presence of sand with largeparticles, the coefficient of friction increases. Combining clay and sand, sandy characteristics has the following: good friability and low dustiness. What is important in draining the marshes, laying country roads. It will protect the pavement from soaking.
When pouring the foundation must be consideredthe composition of the soil, and if sandy loam is found in it (what it is, we have already figured 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 -building. Breakdown of the site, construction of the facility, laying a new road. All these objects require the presence of such a building material as sandy loam. What is it and why not use sand? Yes, he just as the material is much more expensive. And you need to close the pit - and here you can not do without the sandstone ground. Even lower cost loams are not suitable for this purpose due to the high ductility.
In landscape design, garden paths are strewn with sandy lozenges. In the drainage system again. And in the winter than the tracks sprinkled during the ice? Of course, sandstone ground.
On the site where construction is underway, the ground wasloamy. Again, sandy loam is needed. What is it and why not just do without it? And all because loams are highly plastic, and subsequently this characteristic can lead to the appearance of cracks or even to the destruction of the foundation of the building. Sputches will simply reduce the plasticity of the soil, making it more suitable, and also minimize the shrinkage process.
Asphalt mixes are not made withoutpeskogrunta. Align with it and soils. They are going to lay the road in the marshland - they use only this rock, loam is not suitable for road works and their construction, and sand is expensive.
In the production of building materials: ceramics, bricks, blocks - our “hero” is used.
Mining
Deposits where sandy loam is mined are found.almost the entire territory of the Russian Federation. Since it is mined in quarries, as well as in trenches and pits (these are all open-type sites), you can also find another name for this rock. - sand pit. Get it and when digging pits for the construction of multi-storey buildings, to continue to use it on the same construction site.
When building an object sandy loam on the nearThe deposit is taken, since bringing it from another region is, to put it mildly, unprofitable. Industrial type deposits are abundant in the European part of Russia, and in Karelia material is mined in river valleys, although there are also glacial deposits.
It is clear that none can do without sandy loam.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 brought. You can determine if it is sandy or sandy in the following way: wet some of the brought rock and try to roll it - the sand should immediately crumble, because in histhe composition does not contain silt particles, which are responsible for adhesion of the rock. But in the sandy ground they are, and the ball can be rolled out of it. Be alert, and construction work will be performed correctly.
