Title of the articleUtilization of the heat power wastes in waterproof composite materials
Abstract.The use of wastes in the building construction materials industry helps to achieve the following objectives: saving energy and raw resources, waste management, environmental improvement in the regions. A slag of the heat power plants and sulfur of the oil and gas complex are on a first place among the industrial wastes. The using of slag waste as a component of silicate concrete is limited because of a high porous structure of the product materials, which determines their low levels of water resistance and durability. It is possible to eliminate the above drawbacks by forming surface insulation layer by impregnating into sulfur melt. It is especially effective using modifiers of the sulfur melt which lead to the low of viscosity and improvement of impregnating ability of the melt. The efficiency of the use of zinc chloride for this purpose is shown. The depth of impregnation of concrete samples increased significantly The durability of the modified sulfur-impregnated melt concrete samples increased almost 6 times, water absorption decreased by 5 times, the thermal conductivity significantly decreased. X-ray investigations revealed that the surface coating consists mainly of quartz crystal, rhombic sulfur and calcium sulfide. These factors lead to extending of the developed materials applications and use them like insulation in exterior walls.
Keywords.Composition materials, sulfur, ash and slag wastes, rheological properties.
