Figure 3

Cement paste from batch 6 ( w / c = 0 . 2 5 , without silica fume and CNF) in the molds 24 hrs after casting. The beams were exposed to drying conditions during this period and formed shrinkage cracks, some of them causing fracture through the depth of the beams before demolding. The beams have a cross-section with the side length of 15.9 mm (0.625 inch) and length of 240 mm (9.5 in).
