Below is a
sample band 9 answer to a process task 1 question on concrete production.
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.
Answer
The diagrams illustrate the phases and apparatus to make cement and how cement is utilised in the production of concrete for construction.
The production
of cement involves a 5 stage, linear process that begins with the mixing of raw
materials and culminates in the packaging of new cement. Making concrete is a
simpler process that involves mixing four ingredients in a concrete mixer.
Limestone and
clay are crushed and the resulting powder is then mixed before being passed
through a rotating heater. Once heated this mixture travels over a conveyor
belt and is ground through a grinder. Now that the cement has been produced, it
is packaged and transported to a building site where it can be used to make
concrete.
Concrete is
made up of half gravel, quarter sand, 10% water and 15% cement. All of these
are added together in a cylindrical drum and rotated until concrete is yielded. (151 words)
Advice
The first paragraph simply
paraphrases the question. This is done through using synonyms.
The second paragraph gives two
overview sentences. An overview gives
the examiner an overall picture of what is happening. You will notice that I
have mentioned:
- How many
stages there are;
- How raw
materials were used;
- If it is
linear or cyclical;
- what happens
in the beginning; and
- what is the
result.
I have split the overview into two sentences because there are two separate stages.
The third paragraph looks at cement
production in much more detail than the overview. The examiner is looking for
your ability to highlight the main features and sequence them effectively.
The fourth paragraph details the
process of concrete production. This is a much simpler process and does not
require so much sequencing. There are some percentages so it does allow us to
show the examiner that we can use the language of proportions instead of just
repeating all of the numbers.
