N2 - This study examines the civil engineering use of CLTs; if the civil engineering use of CLTs is promoted, the supply of domestically produced CLTs will increase and stabilize, and the price of CLTs will decrease. The purpose of this study is to verify the conditions of use and decomposition in a civil engineering environment. As initial tests, visual observation, 3-point bending tests, and compression tests were conducted to verify the rate of strength degradation and degradation conditions for each elapsed month. As a result, since there was a large strength fluctuation at the same moisture content in terms of the embedded yield strength, an additional verification using small specimens was conducted. The results suggest that the strength reduction in the buried specimens was due to the absorption of water during the burial period, as well as minor but significant biodeterioration.
