▶ Your Answer : The diagrams show how to produce concrete and cement. Cement production is prior to the concrete production. To begine with, cement production is consist of four steps. First, limestone and clay are put into the crusher, become powder type material. After that process the powder goes to mixer to combine two raw ingridents equally. Third level is heating process. The rotating heater rotate powder and heat evenly. The heated powder goes to grinder, finally becoming cement. Compare to the cement production, concrete only need two step for production. Unlike cement proportion of ingridents play heavy role in this process. First of all, 15% of cement, 10% of water, one forths of sand, and half of gravel, which is small stone are put into the concrete mixer. After, concrete mexer combines all the meterials together. Completing the concrete process. In conclusion, to produce the cement, we need to produce concrete by four steps, from clay and limestome to concrete. Completed concrete are goes into the mixer wich creating Concrete which packed and send to construction site. (173) |
