At almost all stages of any serious construction, whether it is a rally of the fossa for the fence or increase the strength of the foundation or wall — everywhere you will need stone building materials. Such materials are divided into natural, the formation of which were engaged in geological eras, and artificial, made by man using various technologies.
The group of natural stone materials includes gravel, crushed stone, sand and rubble stone.
1) gravel — mostly smooth small stones, the largest linear size of which is 6 — 80 millimeters.
2) sand — it is ravine, lake and river. It is indispensable in the preparation of any building solutions and concrete, including concrete structures of its own preparation (rings for the well and so on). Before use, the sand is thoroughly sifted, removing impurities from it, and washed — otherwise the cement may not grasp or the covers will appear in it.
3) Bottom stone — as a rule, is the fragments of such species as limestone, sandstone or dolomite, as well as pieces of various geological rocks forming natural stones. Such building material is divided into tile, forming tiles in natural conditions, and a solidous, laying, as a rule, in layers. The laundry stone used in construction should be deprived of large cracks, pollution, significant stratification and other shortcomings. The sound made by Bout when hit with a metal object should be pure.
4) crushed stone — is formed in the process of crushing monolithic solid geological rocks. Gravel is preferable as a filler for construction solutions, as it has a more strong clutch with cement.
