Influence of Integrated Organomineral Additives on the Basic Properties of Plastering Mortars on Industrial Raw Materials

Abstract

AbstractThe use of local raw materials in the production of building composites has become one of the ways to save resources and reduce their cost. For the Chechen Republic, it is especially important to use local raw materials with accumulated technogenic raw materials both in order to improve the quality of construction products and to utilize them to reduce environmental pollution. Many social infrastructure facilities are being built in Chechen Republic, which require a large amount of high-quality building solutions, in particular, plaster. There are no appropriate raw materials for the production of high-quality plaster solutions on the territory of the republic: quartz sands of the Chervlenny and Vedensky deposits belong to the group of fine and very fine sands. The purpose of this study within the framework of this work is the creation of formulations of high-quality plaster solutions, for which it is proposed to investigate the available technogenic raw materials (screenings of crushing of concrete scrap, ash and slag mixtures) for its suitability for use in these solutions, to develop methods for the enrichment of fine sands and to identify ways to improve their quality. To achieve this goal, the chemical and mineralogical compositions of the feedstock were studied, their main physical and mechanical properties were determined, experimental studies were carried out using methods of mathematical modeling of experiments, and effective methods for obtaining high-quality plaster mixture were established.KeywordsPlaster mortarsMan-made raw materialsComplex modified additiveLocal fine sandsScreenings for crushing concrete scrap
