The question at first glance is so simple that it is enough to designate a numerical value, its dimension - and the answer is ready. But the specific gravity of sand is a somewhat general concept. Yes, and this material, which is used in the construction, restoration or repair, is also different( career or river).Therefore, some explanations are needed, especially in some cases( for example, in the preparation of solutions) compliance with proportions is an indispensable condition for the quality of work.
Firstly, , sand is characterized by the size of fractions. In everyday life, we do not attach importance to this indicator, as a rule. But here for masonry or plaster mortar it is important.
Secondly, , almost any sand, even well washed, contains various impurities, many of which "heavier" it, so it is not entirely correct to rely on the indicators indicated in the special tables.
Thirdly, knowing the specific weight and determining the volume of purchase, it is possible to calculate the transportation required( taking into account its cargo capacity), the number of flights and so on, that is, to optimize all costs associated with payment for products and their delivery to the site.
The purest river is sand, as by definition it has a minimum percentage of impurities. Its density is taken equal to 1.3 tons per "cube".The quarry products are more "dirty", there is a lot of clay in it, that's why the share is bigger. For calculations, use the value 1.4( ± 0.1) t / m³ .
You can find other data - for wet sand or dry;quartz, ravine or mountain;bulk density, true and so on. Accordingly, the ranges from 1,300 to 1,750 kg / m³ .This is interesting, understandable and useful for specialists, and for household calculations the above data is enough.
It remains to add that it was a question of natural building sand( not to be confused with artificial sand).If additional washing is carried out before use, the specific gravity is left unchanged.
