Artificial construction stone – concrete consisting of sand, cement and various improvement characteristics of additives, has been known since ancient Rome. And today, without this strong, frost -resistant, waterproof, fire -resistant and capable of taking the necessary form of material, no construction can do.
There are several classifications taking into account its composition and purpose. Before buying concrete, be sure to clarify what exactly its characteristics are necessary to meet the terms and conditions of hardening, compression density of structures, styling methods and strength.
By purpose, you can buy concrete in Moscow both for the industrial construction of buildings, and for special road, heat -insulating and hydraulic operations. There is also concrete for thin decorative structures and a special chemically stable purpose, withstanding even the strength and temperature of the nuclear explosion, as well as the penetrating radiation radiation.
By the appearance of the connecting binding substance, traditionally cement, gypsum, silicate, as well as slag -bush, polymer concrete containing epoxy resin or its analogues, and asphalt concrete concrete are distinguished.
The most modern branch of varieties is a plast cout or artificial stone. It, unlike cement, has much greater strength, resistance to abrasion, resistance to aggressive and water environments. These unique properties of polymer concrete are used for the manufacture of primer masses, putty and bulk floors. And if the filler contains marble or granite crumbs, then the material will also acquire additional decorative value and will become suitable for the manufacture of countertops, shells of artificial stone pleasant to the touch and even memorial plates.
The so -called light concrete containing gypsum, and expanded clay or organic arbolite as a filler, has relatively ordinary cement composition with a small mass and lower cost. These characteristics allowed the builders to widely introduce light concrete slabs for thermal insulation and the construction of interior partitions.
The possibility of using waste of various industries as fillers of waste is interesting and promising. Block materials obtained at the end of the technological processes of many chemical, aluminum plants, as well as oil refinery enterprises, successfully began to be used in the manufacture of special types of concrete, not inferior to natural clay or crushed stone.
