A method for the production of concrete steps with a box-like casing (11), which on one side with at least one filling opening (12) is provided, with the following process steps: at least one turning point - die (14), in order to achieve a smooth or structured surface, in at least...
The first diagram illustrates the process of cement manufacture, and the second diagram shows the materials that go into the production of concrete. It is clear that there are five stages in the production of cement, beginning with the input of raw materials and ending with bags of the finishe...
These two diagrams reveal the flow diagrams of both cement and concrete production processes with necessary equipment and materials that are used. Mainly, both processes have similarities and differences. They are similar because each of them has more than one input and a single out...
limestone and clay pass through four stages before being bagged ready for use as cement which then accounts for 15% of the four materials used to produce concrete. While the process of making cement uses a number of tools, the production of concrete ...
