FUNDAMENTAL STUDY ON APPLICATION OF FERMENTED WOOD POWDER TO THE BLOCK FOR CREATING SEAWEED BED

Abstract

 This study aims to prevent rocky shore denudation and effectively utilize cutting waste (wood powder) generated during timber processing. Against this background, we have been trying to develop a seaweed bed formation block using concrete containing wood powder fermented using yeast (hereinafter fermented wood powder). In this paper, we investigated the workability and strength of mortar containing fermented wood powder. Then we conducted basic experiments to estimate the number of yeasts and nutrients contained in one specimen. The results suggest that the maximum volume content of fermented wood powder was considered to be approximately 15%, which provides basic data for future concrete block fabrication.
