Task 1: Producing cement and concrete

The information in diagram shows the process of producing cement and how this cement will be used to develop the building.
Initially, the limestone and clay are crushes to create a powder. These materials are put into a mixer. After that, the product passed the rotating heater. While in this stage, this powder is being rotating at a certain temperature. Afterwards the output from rotating heater is grinder into small pieces called cement. Finally this cement will be package into a bag.
In order to produce a concrete, there a several process need to be done. The first step is to combine a 15% of cement with 25% of sand and 50% of gravel and another 10% is water. These combinations will create a concrete. This process is then continuing with putting a concrete into a mixer. And finally the mixer rotated to mix the ingredient to produce a solid concrete.
To summarize this process, both process will go through a mixer with a several materials but the only different is that to produce a cement, we need to mix it at a certain temperature however in producing the concrete, there is no heat applied and furthermore it used water element.
