The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.

The diagrams show the process of

cement

manufacture and

then

how

this

is used for concrete production. As is observed from the graph,

cement

construction involves some complex processes and concrete production is done using water,

cement

and sand in a concrete mixer. The first diagram depicts that, to produce

cement

the limestone and clay are crushed and the produced powder from

this

is passed through a mixer. The power is

then

passed via a rotating heater where heat is supplied constantly and

this

process creates the raw adhesive materials which are passed on a grinder machine to

finally

produce the plaster. The mud is

then

packed and marketed for sale. The second diagram presents how concrete is produced for housing and building work. In the first stage, 15% plaster, 10% water, 25% sand and 50% small stones are mixed in a concrete mixer machine and the machine rotates fast to have the ingredients mixed together to create the concrete.
