The strength of plaster coatings depends on the quality of adhesion of the applied plaster layer with the base. The bases for applying plaster coatings are necessarily prepared, the technology of preparing the bases may differ depending on the coating applied. It is established that the closer the initial structures are in structure, the higher the quality of the plaster coating as a whole. According to geonics, the relationship of structures in building composites is based on basic properties, general physical and mechanical indicators, which equally apply to both the building plaster solution and the base. At the same time, a contact binder is allowed between the base and the plaster layer with similar indicators, the presence of which guarantees reliable adhesion and strength of the resulting coating. The use of plaster solutions on enriched fine substandard sands with complex modified additives makes it possible to improve the technological qualities of the mortar mixture, the physical and mechanical characteristics of plaster solutions and optimize the technology of applying the plaster coating. Successive application of plaster layers on technogenic sands with different size modulus allows creating a base rough coating on the base, which closes the main defects and creates the base for the next layer of plaster solution. The Chechen Republic has extensive reserves of very fine and fine local sands, which in their basic properties are inferior to medium- and coarse-grained sands, but with a rational selection of composition, enrichment of grain composition can be used to produce high-quality construction composites. To enrich the grain composition of fine local sands, it is proposed to use dropouts of concrete scrap crushing, the volumes of which are significant on the territory of the Chechen Republic. Dropout of concrete scrap crushing by chemical composition is suitable for enriching local fine sands and when selecting the composition of the plaster solution increases the physical, mechanical and technological properties of the mortar mixture.

Экономическая ситуация в стране всегда сказывается на темпах развития строительной отрасли, т. к. строительство - это базовая часть народного хозяйства страны. Из-за негативных последствий мировых экономических кризисов большинство строительных организаций модернизируют запланированные стратегии развития для своевременной сдачи объектов в эксплуатацию и сохранения положительного имиджа компаний. Сохранение положительного имиджа строительной организации невозможно без повышения конкурентоспособности организации, для достижения данной цели снижаются производственные издержки. Производственные издержки в строительстве снижают путем применения ресурсо- и энергосберегающих материалов, энергоэффективных технологий и внедрения современных способов организации СМР, повышением производительности выполняемых работ. Данная статья посвящена комплексному сравнению технологий производства внутренних работ по оштукатуриванию двумя способами: механизированным и ручным. Рассмотрены способы нанесения сухой и мокрой штукатурки и основные принципы нанесения штукатурных работ механизированным и ручным способами внутри помещений. Проведен анализ отличия ручного и механизированного способа и выявлена экономическая эффективность наиболее рационального способа. Проведен анализ расчета продолжительности оштукатуривания на примере конкретного объекта недвижимости. The economic situation in the country always affects the pace of development of the construction industry, as construction is the basic part of the national economy. Due to the negative consequences of global economic crises, most construction organizations are modernizing their planned development strategies for the timely commissioning of facilities and maintaining a positive image of the companies. Maintaining a positive image of a construction organization is impossible without increasing the competitiveness of the organization, to achieve this goal production costs are reduced. Production costs in construction are reduced through the use of resource- and energy-saving materials, energy-efficient technologies and the introduction of modern methods of organizing construction and installation work, increasing the productivity of work performed.This article is devoted to a comprehensive comparison of technologies for the production of internal plastering in two ways: mechanized and manual. The methods of applying dry and wet plaster and the basic principles of applying plastering by mechanized and manual methods indoors are considered. An analysis of the differences between the manual and mechanized method is carried out and the economic efficiency of the most rational method is revealed. The analysis of the calculation of the duration of plastering on the example of a particular property.
