The coarse aggregates act like bone in concrete. If we use low quality aggregate in concrete mix, the strength of concrete will be low. The amount of aggregate greatly affects the properties of hardened concrete. Increasing the amount of aggregate at a constant cement content reduce the concrete strength. Strength of concrete can also be affected by the type of aggregate. Such as, angular and rough surface concrete increase the concrete strength.
Portland Cement-The cement and water form a paste that coats the aggregate and sand in the mix. The paste hardens and binds the aggregates and sand together. Water-Water is needed to chemically react with the cement (hydration) and too provide workability with the concrete.. The concrete mix is workable. It can be placed and consolidated properly by yourself or your workmen. 2. Desired qualities of the hardened concrete are met: for example, resistance to freezing and thawing and deicing chemicals, watertightness (low permeability) , wear resistance, and strength.
