Fig. 3: Accelerated hydration of cellulose-supported cement-based (CSC) fiber.
From: Flexible cement fibers with high toughness and water-activated setting behavior for construction
a DTG curves and b XRD patterns of hydrated CSC fibers with different curing time from 1 to 28 d. c–f SEM images showing cellulose skeleton acting as nucleation sites for hydration products. Yellow arrows indicate the cellulose skeleton. Scale bar: 2 μm. g Schematic diagram of the Ca-O connections and H bonds between cement and cellulose during the hydration process. h Schematic diagram of the cellulose network promoting the hydration process of cement. The green coloring indicates the cellulose network and the dashed arrows indicates the water diffusion from cellulose network to cement phase. Source data are provided as a Source Data file.
