The pictures depict the materials and steps used in cement production, and using cement in the concrete-making process for construction purposes. Overall, the cement production process consists of 6 stages while concrete production consists of 2 stages, from raw material to commercial product.
The initial phase of production starts with making a powder using a crusher transferring limestone and clay. Then, the materials are mixed together in specialized equipment, including a mixer and a rotating heater. After being subjected to intense heat in the rotating heater, the materials are transformed into clinker. In the next stage, the clinker is transferred from the grinder before becoming a cement. The final stage of cement-making ends with packaging them into special bags.
As for concrete-making, 4 main different ingredients are used including cement, water, sand, and gravel. Absolutely, all of them are not used in equal amounts. So, 15 percent of our concrete is cement, 10 percent is water, a quarter is sand and a half is gravel. In order for the concrete to be completely ready, these 4 different products are put into the concrete mixer.
