It would seem that it’s easier to take, and buy sand. The most ordinary sand, the mass of which is transported through the yard sandboxes and which Zheki is stocked up for sprinkling paths for the winter. Just? But not, for any builder, even this simplest material has many important values, and the question of how to buy correctly, it sounds very seriously for them.
As you know, various materials are used to perform different operations in construction, they have their own classification and technical characteristics, some are assigned to responsible areas of work, but others, despite the importance and need for construction, can never be used in construction, for example , kindergartens and schools. Building sand is a universal material necessary in all sections of the work – from laying the foundation, to finishing work on wall decoration, and indeed, as the final stage of the entire construction for the children’s sandbox in the courtyard of the house.
Basically, among all types of sand, one is popular – building, this is a common name for the bulk material of natural origin. Where they use construction sand:
as the material of pouring the embankment;
for drainage device;
as a filler of concrete and other solutions used in construction.
For most goals, any of the types of sand can be used: river, sea or even career, however, in order to correctly buy construction sand, you must have an idea of construction and technology.
When erecting embankments, there will be enough ordinary sand from the career, because it can be different in density, in shape of grains and even contain impurities of different rocks – small pebbles and clay, have different density of the material and mass.
For the preparation of concrete, it is better to buy construction sand of river origin, it is more uniform, with a smaller amount of impurities, and almost the same shape of medium sizes. Such sand is indispensable for brick masonry and ceilings, preparation of commodity concrete and black plaster device.
But the sea sand, according to experts, is the cleanest, in terms of the presence of different impurities and interspersed, and the most homogeneous, because it was not without reason that nature worked on its creation of millions of years. It is suitable for the most critical work – finish plaster in surfaces, finishing screed, elimination of cracks and, of course, for children’s sandboxes.
