The sulphur concrete, properties, advantages and application.
Compared to conventional concrete-our concrete has many advantages: high strength (compression and bending), ability to work in tension, high corrosion, chemical and biological stability, low water absorption, high frost resistance, high strength, ability to harden in the frost, repeated use, low price.

Description of the concrete:
Our concrete – an artificial solid material, which is a hardened Serobyan mixture. The composition of the sulfur concrete – a composite material which includes sulfur binder and inert fillers. The range of inert fillers and of fillers wide. In this capacity, can be used crushed stone, sand, gravel, metallurgical slag and other rocks are also used for traditional concrete.
The properties of sulfur concrete is a consequence of its internal structure. Sulfur without the addition of filler is a substance with a homogeneous structure, which means dense arrangement of the molecules relative to each other. The presence of the filler leads to the fact that sulphur molecules “bonded” molecules of the filler and fill the internal space of the resulting substance so that the porosity becomes almost invisible (even under a microscope). Low porosity of concrete is largely due to its scope. This includes the use of concrete as the main material for the construction of waste storages, collectors and treatment facilities of sewage, piles, pipes, sewer trays, various modular designs, in a word, all underground utilities, and marine structures, and dams.
Cost of conventional concrete and the concrete are approximately equal, but the manufacture of sulfur concrete, perhaps even on fine Sands (normal concrete will crumble on such a sand will either require huge cost overruns of binder). And if traditional concrete is at least ternary, the concrete consists of two: sulfur and any of the excipients.
However, it should be noted that the properties of sulfur concrete to a greater extent than in the case of a cement concrete depends on accurate compliance and control of technological process and quality control of incoming raw materials and all stages of production. Our concrete environmentally friendly while maintaining the temperature of cooking up to 150 0C. At temperatures above 150 0C is the emission of hydrogen sulfide and sulfur dioxide in the production process and in the operation of the product.
The advantages of concrete over conventional concrete:
– high strength (compressive and Flexural),
– the ability of this material to work tensile
– high corrosion, chemical and biological stability,
– low water absorption,
– high frost resistance,
– fast curing,
– the ability to harden in the frost,
– reusability (recycling),
– slight shrinkage,
– low price.

The application of sulfur concrete:
– in the construction of buildings and structures in the period of operation, which are increased requirements for resistance to aggressive environments, frost and weather resistance, impermeability, wear resistance (including elements of road surfaces: plates, paving tiles, mechanical draughts, side stones, road barriers; construction exposed to salt aggression: flooring, drain trays, foundations; engineering structures, collector rings, sewers, sewage treatment plants),
– in the industrial, agricultural, storage facilities for bulk and liquid materials.
