3. 3 • Cement is a fine, soft, powdery-type substance • It is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale • When cement is mixed with water, it can bind sand and aggregates into a hard, solid mass called concrete Cement.
One major disadvantage of concrete is its susceptibility to damage by single or multiple freeze-thaw cycles. However, concrete can be made frost-resistant by using air-entraining admixtures. Concrete is routinely air-entrained in the Northern U.S. and Canada. ACI Mix Design Approximate mixing water (lb./yd.3) and air content for
