Disclosed is an essentially shaped cementitious product wherein the direct tensile strength of the product as determined by ASTM C307 is at least 120% of a predicted direct tensile strength of the product per an equation selected from the group consisting of f'dt = 0.06*f'c, f'dt = 0.07*f'c, f'dt = 0.08*f'c and f'dt = 0.11*f'c, and wherein the the flexural strength of the product as determined by ASTM C348 is at least 150% of a predicted flexural strength of the product per an equation selected from the group consisting of f'r = 0.1*f'c, f'r = 0.17*f'c, f'r = 9.5*((f'c)^0.5) and f'r = 7.5*((f'c)^0.5). |
