Social and technological aspects of building materials production in the concept of a smart city

Abstract

Abstract The concept of a smart city is based on the improvement of the quality of human life in a comfortable environment. Depending on specific goals, priority is given to certain environmental factors. Among the most important factors, the analysis allows highlighting social inequality, ecology, sustainability, the use of local conditions, resource optimization, and benefits for citizens. The creation of infrastructure that ensures and supports the development of cities is largely determined by the state of the construction sector. In the field of construction, we are talking about the choice of socio-technological aspects of the production of materials that correspond to the concept of a smart city. Therefore, the choice of building material is determined by the social significance of its availability, environmental friendliness, technological feasibility from the standpoint of durability, the possibility of using local raw materials, and the possibility of involving technogenic materials. Based on the SWOT analysis method, ceramic tiles have strong technological aspects. The article presents the results of optimization of the raw material composition of ceramic tiles, which includes anthropogenic material - cullet and local raw material - chalk, and technological parameters (pressing pressure and firing temperature). As a result of the work, the rational content of the studied floodplains (cullet and chalk) in the raw material mixture was determined - 17-25% for the production of facing ceramic tiles. It is established that press pressure is a factor in the formation of a structure that allows reducing the temperature of roasting ceramic tiles.
