How to Prevent Plastic Shrinkage Cracking in Silica Fume Concrete
Plastic shrinkage cracking in silica fume concrete can cut a slab’s service life by 30% or more before curing even begins. When bleed water evaporates faster than it rises, capillary tension builds in the near-surface paste – and at w/b ratios below 0.40, silica fume’s extreme fineness virtually eliminates bleeding. Engineers specifying high-performance concrete (HPC) […]
