Method for evaluating long-term reliability of resin concrete, method for evaluating CO2 concentration-dependent strength decrease time, and method for estimating strength decrease behavior

摘要

PROBLEM TO BE SOLVED: To provide an estimation method capable of precisely estimating degradation over time of a resin concrete, the temperature dependency strength reduction speed of the resin concrete, and the COdensity dependency of strength reduction time of the resin concrete.SOLUTION: The estimation method of strength reducing behavior of a resin concrete, includes the steps of: accelerating carbonation on the aggregate surface of a resin concrete under an atmosphere of substantially a constant temperature, a constant relative humidity and a constant COdensity; measuring the strength reducing behavior of the resin concrete; and estimating the strength reducing behavior of the resin concrete under actual circumstances.SELECTED DRAWING: Figure 1
