The article deals with studying the ways of optimizing
the amount of chemical additives in the wood-concrete
material, i.e. arbolite, which contains foamed
polystyrene gravel aggregate. To make arbolite
honeycombed structure more conglomerated a nonreactive
aggregate, i.e. hogged chips, has been partially
replaced with foamed polystyrene gravel aggregate
which has a mean particle size equal to a concrete
pocket size. The article also deals with various
additives to be used, taking into account the nonreactive
aggregate type and its quality, the composite
density and its reinforcement level. All chemical
additives have been chosen to make the initial material
more porous, to produce a film covering the aggregate
surface and to speed up the process of concrete
hardening. To solve to above problems a series of
experiments was carried out, the latter studied various
combinations of factors changing at certain levels. The
results of studying the foamed polystyrene gravel
aggregate influence on the arbolite structure and its
characteristics were used to make a choice of the
arbolite composition. The main criterion of the optimal
amount of chemical additives has been considered the
arbolite strength. The experimental data processing has
resulted in the finite regression model which describes
the chemical additive amount influence on the arbolite
strength. The tables in the article show the levels of
technological factors varying and the matrix of
planning the experiments to be carried out in order to
optimize the chemical additive amount. As a result of
the research accomplished the optimal amount of
chemical additives has been determined which enables
to produce the arbolite with some foamed polystyrene
gravel aggregate in its composition
