The ideal concrete of the engineer and builder should be of uniform, monolithic structure with the strength and density of granite. It should be as waterproof as asphalt and as flameproof as fire clay. It should be mixed with only the proper amount of water, yet every particle of cement should receive perfect hydration. There should be no pause between the mixing and the placing; from the moment the water touches the cement until the concrete is poured into its final position, there should be continuous and thorough mixing. No crevices should be permitted between successive pourings nor should there be any cracks or voids. The pourings should be followed by heavy tamping, but not a stroke should be allowed after the initial set. Perfect adhesion should be secured to all reinforcing steel and to earlier work.
