Cement is a key ingredient of concrete, typically making up 10 to 15 percent of the concrete mix by volume. Portland cement and portland-limestone cement are the most common types of cement used in concrete. In concrete, a paste made of cement and water is mixed with aggregates (sand, gravel, or crushed stone).
Water. You can use almost any natural water that is drinkable and has no pronounced taste or odor as mixing water for concrete. Excessive impurities in mixing water can affect setting time and concrete strength, and can also cause efflorescence, staining, corrosion of reinforcement, volume instability, and reduced durability.
