Currently, intensive research is being conducted, both in Russia and abroad, to study the general principles, problems and solutions in the development of effective composite materials for construction purposes. It is shown that it is possible to use unconventional aluminosilicate raw materials represented by clay rocks of the incomplete stage of mineral formation as a raw material for the production of non-autoclaved silicate blocks of casting molding process. These raw materials due to the peculiarities of its material composition actively interact with the cementing component in non-autoclave conditions, with the formation of cementing compounds of the CaO-SiO2-Al2O3- H2O system, which provides high physical and mechanical performance of non-autoclave silicate products.
Представлены результаты процедуры объемно-пространственного картирования условий обжига по UV-VIS-NIR-спектру керамических кирпичей из одной партии методами многомерного анализа. Методом главных компонент идентифицированы полосы поглощения спектра, которые приписывают центрам окраски железосодержащих примесей. Определена дискриминантная способность координат цвета a* > b* > L* при градации изделий на группы образцов с аналогичными цветовыми характеристиками. Объемно-пространственное картирование условий обжига по UV-VIS-NIR-спектрам керамических изделий позволяет производить отбор образцов для испытаний в контрольных точках по объему партии изделий.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
