WAYS OF OPTIMIZING THE AMOUNT OF CHEMICAL ADDITIVES IN POROUS ARBOLITE CONTAINING FOAMED POLYSTYRENE GRAVEL AGGREGATE

abstract 1281704017 issue 128 pp. 258 – 267 28.04.2017 ru 275
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
