OtherIngredients. Almost any natural water that is drinkable and has no pronounced taste or odor may be used as mixing water forconcrete. Excessive impurities in mixing water not only may affect setting time andconcretestrength, but can also cause efflorescence, staining, corrosion of reinforcement, volume instability, and reduced durability.

Historically,cementcan be traced back to the early Roman Empire, and contributed to the building of the great structures of the Roman Empire. By varying the amounts and types of the same basicingredients,cementwith various properties may be obtained. By further varying theingredients, even more differing cements are manufactured.
