The effects of silica fume and aggregate size on the softening response and brittleness of high strength concretes were investigated by measuring the fracture energy GF, the characteristic length l,, and brittleness index B. Based on the fracture tests and microscopic studies at the aggregate-matrix
Laboratory concretes containing only coarse aggregates and 0, 10, or 20% silica fume as a cement replacement were prepared at a constant water-to-solids ratio and sampled at 1, 7, and 28 days. Scanning electron microscopy was utilized to monitor the progress of the hydration reactions both in the bu
