The picture above illustrates the equipment and the process of fabricating

cement

and concrete for building purposes.

Overall

,

cement

production needs several stages to make

cement

while

concrete production just needs two steps until the concrete is finished. To build a building needs to follow several steps, from making

cement

, 10% water, 25% of sand and 50% small stones, To compare the execution of

cement

and concrete is the process.In

this
