Abstract

In recent years, studies of a number of foreign scientists have been reported on the possibility of using loess loam as the main constituent of the ceramic composition in the production of clinker brick. Loess loam is considered a common raw material. In this paper, we consider the purpose, which is research on the study and development of methods that regulate the physicochemical processes occurring in the mass of loess-like loam under the influence of temperature. As a result of these studies it will be possible to intensify thermochemical processes and achieve high-quality products with minimal energy costs. Thus, the possible chemical interactions between minerals of loess-like loam have been theoretically studied, the medium of which is given priority to the decomposition of kaolinite. To intensify the decomposition process of refractory minerals, it is recommended to use an alkali additive in an amount of up to 5%, with a weight ratio of coal.

Highlights

  • Rapid development of construction of housing and industrial buildings and structures dictates the need to increase the output of wall materials

  • Loesslike loams in Uzbekistan were formed as a result of the deposition of dust brought by the wind mainly from deserts, and there are silty deposits of various rivers carrying products of rock destruction in their waters

  • The purpose of our research is to study and develop methods that regulate the physicochemical processes occurring in the mass of loess-like loam under the influence of temperature

Summary

Introduction

Rapid development of construction of housing and industrial buildings and structures dictates the need to increase the output of wall materials. The wall building materials include ceramic bricks, obtained by burning in a high-temperature environment. The main cheap raw material for the production of ceramic building bricks is loess loam, whose reserves in Uzbekistan are unlimited. Loesslike loams in Uzbekistan were formed as a result of the deposition of dust brought by the wind mainly from deserts, and there are silty deposits of various rivers carrying products of rock destruction in their waters. The purpose of our research is to study and develop methods that regulate the physicochemical processes occurring in the mass of loess-like loam under the influence of temperature. As a result of these studies it will be possible to intensify thermochemical processes and achieve highquality products with minimal energy costs
