Whom are not a secret that for the construction of even a small house on six acres in your suburbs difficult to do without the use of nonmetallic materials. They have over the years have a huge role in the construction industry. And even in spite of the achievements in the development of new building components, synthetic analogues of them in today's day is not available. The beginning of their use began in the days of ancient civilizations. Over the centuries humans have changed the look of the planet, and basic materials for the building still remained consistent sand and stone. Because of their resistance to external factors to date have remained enormous, even by today's standards, the construction of ancient cultures. These great buildings, regardless of the past century since the end of construction, were all the same and that in times of great kings and generals of antiquity.
In our time, sand is a member of numerous mortar required for the cladding, finishing and numerous other works. His presence significantly reduces the amount of binder and gives the composition of the desired quality. As aggregate for concrete and plaster, it reduces the thermal conductivity and increases the strength – more to repair the room. Due to the chemical resistance to acids and aggressive media and the highest sand temperatures used in the chemical industry, foundries and construction, production of cement, brick, porcelain, concrete, porcelain, asphalt, roofing products, etc. Glass is also not possible without the sand. Issued a certificate of conformity in the sand at the request of the supplier or manufacturer, then there goes voluntarily.
Certification involves sand required to obtain sanitary-epidemiological certificate. In modern building for the erection of buildings, often in road construction, wide use has macadam (crushed stone) that are used in various construction and repair work. To improve required performance indicators, gravel must comply with the rules. It must include the prescribed level of purity, strength, radioactivity, and hardiness. This is due to the wide Using this raw material in the production of insulating components used in cold climatic conditions of our country. The chippings shall be manufactured in accordance with the requirements of the State standard. Sand and gravel for a long time will be essential materials in the construction industry and in other industries.
