    Compressive strength of high strength concrete mix is usually greater than 6,000 pounds per square inch.. High strength concrete is made by lowering the water cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement, which might reduce the strength at the cement aggregate bond.
