Abstract
In recent years, cases of temporary construction materials being left in the ground following excavation work have been increasing. In this context, the application of biodegradable resin concrete as a new temporary construction material that does not require removal might be useful. Currently, various types of biodegradable resin are used, each with different degradation characteristics. In order to investigate the level of degradation of biodegradable resin concrete according to the resin, PBSA and PLA resins were used, and comparison experiments examining mechanical characteristics and surface degradation were conducted. As a result, the surface degradation of the biodegradable resin concrete made using PBSA was found to be more remarkable compared with that made using PLA. On the other hand, the early-age strength of PLA specimens was found to be higher than PBSA specimens, and the strength retention period of PLA specimens was longer than that of PBSA specimens.
