Microstructure and Compressive Performance of Solidified Waste Resin Concentrate

摘要

To study the microstructure and mechanical property of cement-solidified waste resin concentrate, and research into the feasibility and effectiveness of solidification of waste resin concentrate, the researchers conducted microscopic CT scan on cement-solidified waste, reconstructed 3D model of resin particle distribution, and performed compression test on samples. The result showed that resin particles in cement-solidified waste resin concentrate are evenly distributed, and the comprehensive strength of the cement-solidified waste, though lowered to some extent after soaking, complies with GB 14569.1-2011 both before and after soaking. Therefore, solidification of waste resin concentrate for radioactive waste disposal is feasible and effective.
