| summary(En) : | The aim of this study is to establish the coarse sand-block testing method for rapid evaluation of preserving effect of wood treated with preservative in the laboratory. This method used is coarse sand in place of soil as culture medium. As a first step, we studied the condition of sand culture medium for methodology of coarse sand-block testing. The discussion on the moisture content, nutriment, size of sand grain, disposition of test pieces, term and temperature of incubation and putting time of test pieces in the sand culture medium was tried. The results of weight loss rate and compressive strength obtained was analysed by statistics. According to the results, we can recommend the sand culture medium of 100∼120ml water content, 3∼4.5 g glucose, 0.2∼0.3 g peptone and 10∼40 mesh sand grain for the testing method of evaluating wood preservative. |
