And with the increase of GO and GO–NS-content, the strength changes in both dry and wet states showed a trend of increasing and then decreasing, with a turning point of 0.06%, which means that the optimal strength enhancement was reached at this point.

However, it is possible that agglomeration occurred due to the high content of GO and GO–NS; i.e., a negative trend was observed above 0.06%.
Overall, the mass loss showed a decreasing and then increasing trend with the increase of GO and GO–NS content—both having reached the lowest mass loss at 0.06%—and an increasing trend with the increase of the number of freeze–thaw cycles.
The consistency of modified sticky rice–lime paste showed a decreasing trend with the increase of GO and GO–NS content, which was attributed to the fact that both GO and GO–NS were two-dimensional folded structures with more hydrophilic functional groups on their surfaces [ 16 , 42 ], which had a certain effect of adsorption of water, which would reduce the content of free water in the paste, resulting in a decrease in the fluidity.
