Challenges and Benefits of Utilizing Carbon Nanofilaments in Cementitious Materials
Figure 5
A beam made from batch 9, 24 hrs after casting and immediately after demolding. Batch 9 beams were produced in the same condition (no curing) and with the same mix proportions as those of the beams shown in Figure 4 (, with silica fume to cement ratio of 20 wt%). The only difference is that batch 9 contains CNF with the concentration of 1.0% of cement mass. There are only very shallow shrinkage cracks at the surface. The beams did not break through any of those cracks during bending test.
