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. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The flow chart illustrates the steps and tool

that is

Linking Words

employed to manufacture sand,and how concrete is made from adhesive .

Overall

Linking Words

,the production of mud is seven stages with four pieces of equipment.The tools include a crusher,a blender, a rotating heater and a grinder,

while

Linking Words

the production of concrete is two procedures with just one machine (concrete blender).

The first step is

Linking Words

that the required quantity of limestone and clay is poured into a crusher,

this

Linking Words

is to reduce the size of the materials into powder .

The next step is

Linking Words

that the crushed limestones and clay are

then

Linking Words

transferred into a machine called a mixer in other to mix the materials together.After the proper mixture has taken place,it

thereafter

Linking Words

moved into a tool called a rotating heater where heat is introduced for the powder to become dry.

Following

Linking Words

this

Linking Words

,the dried mixture is transferred into a grinder to it a fine texture which is known as plaster.At the final stage,the product is packaged into a bag ready to be used for construction. Moving to the manufacturing of concrete,

firstly

Linking Words

,15% of sand and 10% of water is poured into a container known as a concrete food processor.

Secondly

Linking Words

, 25% of sand and 50% of gravel(small stones) are

also

Linking Words

added to the contents already in the blender.The mixture of these four materials results in concrete

that is

Linking Words

used for building.
