An Investigation into the Properties and Microstructure of Cement Mixtures Modified with Cellulose Nanocrystal

This paper aims to examine the effect of cellulose nanocrystals (CNC) on the hydration, transport behavior, and microstructure of cement mixtures. The addition of CNC delayed hydration at an early age but improved hydration at later ages. A small increase in the electrical resistivity of the cement...
