Abstract:
1. A method of producing a concrete having a combination of strength and toughness, comprising: mixing first constituents comprising: wherein said sand is provided at a mass ratio of about 0.75 to about 1.25 of the mass of said cement; wherein said silica fume is provided at a mass ratio of about 0.15 to 0.4 of the mass of said cement; wherein said silica flour is provided at a mass ratio of about 0.15 to about 0.3 of the mass of said cement; wherein said microinclusions are provided at a mass ratio of up to about 0.35 of the mass of said cement, and wherein mixing said first constituents yields a first homogeneous mix; blending second constituents comprising: wherein said water is provided at a mass ratio of about 0.2 to about 0.35 of the mass of said cement, and wherein blending said second constituents yields a second homogeneous mix; mixing said first homogeneous mix with said second homogeneous mix to form a uniform cement-containing paste; blending macrofibers into said uniform cement-containing paste such that said macrofibers are distributed approximately uniformly in a resultant cement-containing paste; shaping said resultant cement-containing paste; and hydrating said shaped resultant cement-containing paste to establish said concrete.
