Abstract
In the article provides a brief overview of the specific features of cellulose-containing aggregates of plant origin. The degree of influence of these features of cellulose-containing aggregates of plant origin on the processes of structure formation and the physical and mechanical properties of arbolitic concrete is shown. The aim of the study is to obtain an arbolite concrete of reduced density. The choice and justification of the type of binder for arbolitic concrete, the systematization of the obtained data was made. Composites based on cellulose-containing aggregate with various kinds of binder are analyzed. The optimum ratio of components in the system "organic filler - astringent". The selection of the optimal ratio between fractions of organic aggregate is made. Based on the results of experimental data, ES models of the influence of the fractional composition of organic aggregate on the properties of arbolitic concrete are calculated. The multiparametric optimization of the composition of arbolit concrete with a density ρ <400 kg / m3 was carried out using mathematical modeling methods for strength and average density parameters, taking into account the composition of the composite gypsum binder, the fractional composition of the bonfire, and the ratio of the components in the "organic filler-binder" system. The optimal compositions of ablit-concrete provide a strength class of B0.35 and B0.5 with a density ρ≤300 kg / m3 for these strength classes for arbolitic concrete. The developed compositions of arbolit concrete on the complex of quality criteria are optimized.
