For the manufacture of a concrete or cement mixture, for the formation of a landscape, you can not do without sand to strengthen the ground for the foundation. Of course, it is best to buy sand with delivery, the price of which will always depend on its quality.
On the market, sand is classified according to the processing and at the place of origin. Thus, it happens:
River sand. It is mined from rivers. It differs in a high degree of cleaning, as well as those that there are no extraneous inclusions, impurities and pebbles in it.
Nice sand. It is mined by washing in quarries. Thus, they wash all the clay from it.
Sowed sand. It is mined in a career. It is cleaned of large fractions and stones, used when pouring sections, the construction of roads, in the production of the solution, in concrete production, in finishing work, for decorative purposes and in the processes of water filtration.
We also note that the sand is of two types: artificial and natural. Natural has the highest quality, since its formation occurs due to the destruction of quartz crystals.
If we talk about the use of sand, then of course each of them is better to use in certain moments. So for concrete work it is best to use sea sand, due to the fact that it passes and meets the requirements of GOST, since it undergoes multi -stage cleaning. If you need the components of the finish mixtures and want to get concrete of the highest sample, you should purchase this type of sand with delivery. If we talk about river sand, then it cannot be called not an expensive replacement of the sea, and the quality of the grains below. Use it in the construction of foundations, when mixing the solutions of concrete.
As for career sand- this is a sand of artificial origin. Most often it is cleaned by washing or sifting. It is best used in works where you are not presented with overstated quality requirements. Well, here, and the sandy is sand, which is divided into several categories: dusty, rough and small sand. If you need an inexpensive construction sand, it is best to purchase a sandy loan, because, despite the cost, it has such positive qualities as: when the moisture is exposed, it is less sat down and is easily mined. It is best to use it for adding foundations, in landscape construction or for the formation of a road embankment.
