Influence of the Graphene Oxide on the Pore-Throat Connection of Cement Waste Rock Backfill.

ue to the nucleation effect that promotes the growth of hydration products and the pore-infilling effect that fills and divides the pores and pore-throat, both of which contribute to the optimization of microstructure; (2) With the increase of pore-throat size, the porosity of CWRB specimens showed a decreasing trend, and the pores shifted from large equivalent pore size distribution to small equivalent pore size distribution, which was due to the fact that the original small pore throat was no longer used as a channel to connect the pores, but split the original large pores; (3) A large number of pore-throat w
