Manufacturing of cement involves some complex procedures which use clay and limestone as the main material. Meanwhile, for making concrete only use blending method to mix cement, water, sand, and grave in favour.Look at details in the first picture, cement production is begun with crushing of limestone and clay. This process will produce powder that blending in a mixer. Through a pipe the mixture will be heated by using rotating heater which spinning all the time to make perfect blend. Then, it flows to grinder for smoother cement. The last step is packing the cement in the bags.In the second picture, it interprets the manufacturing of concrete. Material of concrete is dominated by small stones which is called gravel. This material makes up 50 percent of the ingredients. Next, it is blended in a mixer with 15 percent of cement and 25 percent of sand. Finally, it is added by 10 percent water for completing the process to make a pasta of concrete.
