The pictures illustrate the phases and apparatus to make cement and how cement is utilised in the production of concrete for construction.
Overview: Trong 2 câu, nêu rõ tổng số bước có trong quy trình, và nêu rõ bước đầu/bước cuối. Nếu có 2 hình vẽ như ví dụ thì có thể dành mỗi câu để miêu tả một hình vẽ
Cement-making: 5 stages, begins with mixing raw materials, ends with packaging
Concrete-making: mix 4 ingredients
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.
Body paragraph 1: Miêu tả chi tiết từng bước. Nối các bước với nhau bằng sequencing language nếu có thể (then, before, after, once, as soon as,...)
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.
Body paragraph 2: Miêu tả chi tiết từng bước. Nối các bước với nhau bằng sequencing language nếu có thể (then, before, after, once, as soon as,...). Riêng ở ví dụ này, do có 2 hình vẽ nên đoạn thứ 2 sẽ dùng để miêu tả biểu đồ thứ 2.
Concrete is made up of half gravel, quarter sand, 10% water and 15
