Concrete vs Cement: What's The Difference? | Howden

To make concrete a mixture of portland cement (10-15%) and water (15-20%) make a paste. This paste is then mixed with aggregates (65-75%) such as sand and gravel, or crushed stone. As the cement and water mix, they harden and bind the aggregates into an impenetrable rock-like mass. Therefore: Cement + Aggregates + Water = Concrete.
