Diuzhylova N. Autoclaved aerated concrete, modified ferroalloy production associated with the product

The object of research is the process of structure formation directed AAC based on cement-lime-silica composition, associated with the product of the modified ferroalloy production. The aim of the thesis is to provide a cellular aerated with desired properties, associated with the product of the modified ferroalloy production. Research methods - modern methods of physical and chemical analysis, statistical methods of experimental design. The novelty of the set-composite construction material autoclave cellular structure modified ferroalloy production associated with the product, providing directions for forming a porous structure due to the synthesis of increased amounts of hydrate neoplasms - hydrosilicate phases that enhance the strength of the modified formulations. It is shown that the introduction of the optimal number (6%) of dry gas cleaning dust of manganese alloys (DGCDMA) greatly increases the amount of gas emitted in the later stages of the swelling of the array, when the mixture is in the visco-plastic state, and less time in front of a set of plastic strength sharply due to the formation of calcium hydro. With the introduction of the optimal number (6%) of waste crushing and screening of ferrosilicon (WCSFS) the amount of gas emitted in the later stages of the swelling of the array increases slightly, but the more intense is the process of a set of plastic strength before cutting through the formation of calcium hydro. It was determined that the formation of the porous structure of porous aerated by modifying ferroalloy production associated with the product produced increased amounts of private micro-and mesopores in the range from 3.7 to 26.2 nm, which reduces the thermal conductivity of 1.2 times compared to the aerated concrete controlling the composition. Results have been implemented in the production of building materials. Define the technical and economic feasibility of the development. Industry - construction.
