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).
