Abstract
Technology for producing of modified arbolit with directional laying of the aggregate is presented. To im-plement the technology the additive modifier of arbolit mixture Arbel is developed, which reduces the effect of harmful substances in the wood filler and allows to get a product with lower operating humidity, not subject to sul-fate corrosion. Arbolit with the addition of calcium chloride draws in its natural state 2,5 – 3 % more water than with the addition of Arbel and without additives. Moreover, humidity has a significant effect on the strength of arbolit. Arbolit shows the greatest strength in its natural state. For arbolit without additives humidity is 11,6 %, and with the addition of Arbel – 11,9 %, with the addition of calcium chloride – 13,3 %. Additionally according to the results of tests we determined the coefficients of softening and maintaining of strength of arbolit. The investiga-tions carried out allow us to draw a conclusion about the benefits of using arbolit obtained by vibrational technol-ogy using the additive Arbel versus traditional arbolit. This provides reduced equilibrium moisture, 5 % of water absorption, 25 % of the time to achieve the necessary humidity and increase water resistance and durability.
