STUDY OF REGIONAL FACTORS AND BASIC PROPERTIES OF RAW MATERIALS FOR THE BIOCONCRETE FILLER SELECTION

Abstract

Abstract. The article analyzes the possibility of using various organic aggregates for bioconcrete and the latest publicly available statistics on the cultivation of the main types of agricultural crops in Ukraine, as well as the amount of production waste during their processing. The world experience in the use of bio-concrete in residential and public construction is studied and summarized. The optimal forms of structural elements and technological features of the use of concrete mixtures with organic aggregate are determined. The main tasks of theoretical and experimental tests are declared. The two most optimal types of mixtures for insulation were selected by preliminary analytical comparison. A program was developed and the main methods and materials for laboratory tests were selected. The key physical, mechanical, and chemical characteristics of some components of bioconcrete were studied, and the dependence of the level of hygroscopicity of raw materials on time and humidity was experimentally determined. Three main compositions of concrete mixtures and bituminous aggregates were experimentally selected. Taking into account the experience of using woodworking industry waste as a filler to prevent fungal damage to the organic component of biobased concrete, phenols were used, which proved to be much more effective in interaction with the proposed composition. The research revealed the peculiarities of the use of bitumen in biobeton with the subsequent need to study the optimal temperature range of the components during further mixing.
