Different mineral species are used in construction, including magmatic rocks (like granite), metamorphic rocks (like a shale) or sedimentary rocks (like sand or clay). Sometimes they are combined by creating individual materials, for example, the SPPS fractions 0-80 is a crushed stone-sand mixture that can be used to lay a temporary road or arrange the base of motorways. Mineral species are also sold in a processed form for independent mixing or as part of building mixtures.
From rocks of different types, magnificent components for concrete are obtained, only rocks are rarely used in construction. As a rule, they are processed. For example, countertops (well -known granite countertops are cut out of rocks, and granite is a magmatic intrusive rock, which consists of minerals: quartz, field spar, mica and plagioclase). In order for mountain materials to be used in various mixtures for construction, they are crushed. In this case, the crushed stone is obtained. There is gravel as an alternative to crushed stone – these are the same tiny stones of different fractions, but they are formed naturally without human participation.
When it comes to construction or landscape design, rocks are used more often than people think. Concrete, for example, is a combination of cement with mineral species. Cement is produced by a person, and rocks and minerals – nature. It is impossible to create concrete without cement or units. Moreover, many qualities of concrete depend on aggregates.
Crushed stone, gravel and sand is a three of the most popular natural materials in construction. Of all these materials, only crushed stone undergoes hard processing in crushers, although all three materials should undergo different types of cleaning and sorting. Cleansing from different impurities improve the quality of materials, and the quality of concrete in which they are used depends on this. Although for the formation of landscape designs, small amounts of sand or clay impurities in gravel are not so important, but the fractions of materials still matter.
Gravel from crushed stone differs in that it is smooth. Where the paths are laid with gravel, it is quite important. However, mountain gravel can have a rough surface. The most smooth gravel is river. In addition, river gravel is cleaner. For landscape design, the smoothness of gravel is a useful property, but for adhesion to the solution in concrete, the smoothness of the aggregate is not its advantage. Better for such a solution, pebbles with corners cling, that is, crushed stone. This is why there is interest in crushing crushes in crushers.
Sand in construction is also popular. Moreover, like rocks, sand has many types. Moreover, in Russia there is a GOST that describes the standard for building sand (where it is mined, as is enriched). Sand prices depend on its quality and career where it was mined. The sand not processed is the cheapest (this is sand with lumps, dust, impurities, clay, etc. p.). As soon as the sand is processed, its price increases sharply. Moreover, the difference in price will also be noticeable between sifted sand and washed sand. The most expensive sandy sand.
