A Review of Data on Biodegradable Resin Concrete and Future Tasks

Biodegradable resin concrete is made of biodegradable resin and aggregate. The experiments on this new concrete were started in 2012, and six papers were published. The strength degradation of biodegradable resin concrete was evaluated using the results of the three-point bending and compression tests, and the surface degradation was evaluated using the binarized photo data. The results showed that the decomposition of the biodegradable resin by microorganisms and the bond strength reduction between the biodegradable resin and aggregate by hydrolysis caused the degradation mechanism. Moreover, to estimate the fatigue life and clarify the strength retention period of biodegradable resin concrete, the statistical deterioration prediction formulas were introduced using the Weibull distribution. This provided the appropriate estimates associated with the strength retention period of biodegradable resin concrete. This paper summarizes the experimental results on biodegradable resin concrete and describes future tasks.
