The carbon concrete was experimentally made by mixing with the concrete and carbonization powder which dealt with the lumber from thinning in high temperature in order to effectively utilize lumber from thinning which is forestry waste with the forestry activation by lumber from thinning utilization cooperative association in Fukui Prefecture. The purposes of this study are to verify that the cause of the water quality accident arose in the concrete crush construction was a sudden change of pH. The pH of the river was increased by the fine-grain fraction of crushed concrete, and the aquatic organisms such as fish were killed. Carbon concrete was compared experimentally using Oryzias latipes in order to examine the effect of the carbon concrete on the aquatic organism. As the result, it is confirmed that the carbon concrete was more excellent in the adsorption the survival rate of Oryzias latipes was higher than the conventional concrete, and the effectiveness of carbon concrete was verified in using in aqueous environments such as the river from recycling lumber from thinning. Still, Prefecture Carbon Concrete Society was established at present, and carbon concrete was designated in the prefecture recognition recycling product in November, last year.
