Overall

it is clear that

there are two main processes for getting concrete for building objectives. The process begins with getting

ready and ends with mixing concrete. In the first place, limestone and mud, which are collected from their sources, will be spread on their trays before crushing by a two-wheeled crusher. Powder, an outcome of the previous stage, passes through a mixer and will be heated in a rotating heater which rotates all the time in order to let a flame
