Full Answer. Portland cement is the main ingredient in concrete, which is made by adding rock, sand and water to form a paste that hardens. Concrete is made stronger by adding more cement and is weakened by adding more water. Concrete is used in most buildings, bridges and tunnels due to its strength.
