Ordinary portland Content is used where the heat of hydration of the concrete is required to be minimized, where increased resistance is required against chlorideion, sulphate of seawater attack, or to reduce the likelihood of alkali aggregate reaction.
Slag Content is used where the heat of hydration of the concrete is required to be minimized, where increased resistance is required against chlorideion, sulphate of seawater attack, or to reduce the likelihood of alkali aggregate reaction.
Opc cement Produces less heat of hydration & offers greater resistance to attack of aggressive waters. It also reduces leaching of Calcium Hydroxide liberated during hydration of cement making concrete impermeable & corrosion resistant. Consistently imparts higher 28 days compressive strength touching as high as 44 to 46 MPa.
