Water

May 28 2010Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f' c) and the maximum water-to-cement ratio (w/c) These two values are inversely related which means that as the water-to-cement ratio increases the compressive strength decreases

Types of Concrete and their Characteristics

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
