The given pictography illustrates the phases and appliances operated in the processing of cement, and how cement is utilized in concrete formation.
It is observed that cement is a five-stage, linear process, that begins with the crushing of raw materials and culminates with the packaging of produced cement, while concrete is a single-step process, involves the mixing of four types of substances.
Initially, limestone and clay is crushed to obtain a powder that is then mixed and passed into a rotating heater. In the next step, the heated material travels over a conveyor and ground by a grinder in order to form cement.
Following the process, the concrete is manufactured using a half percentage of gravel, a quarter of sand, 15% of cement, and 10% of water, and it is presented that the gravel is composed of small stones. They are mixed in a concrete mixer which results in the formation of concrete.
