Abstract

This paper design the method of strengthening the recycled aggregate by nano-solution. By testing the surface hardness and pore structure changes of the recycled aggregate after immersing in different concentrations of nano-solutions (nano calcium carbonate, nano-silica, sodium silicate) together with SEM observations of the immersion method of recycled aggregate surface structure before and after immersion we found that the nano-solution can effectively improve pore structure and the surface hardness of recycled aggregate.
