Someone asked me for help with the diagram task below. I wrote one paragraph about this diagram in this lesson back in 2012, but I didn't finish the full answer. So let's take another look:
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.
Of course, we're going to describe the steps in the cement-making process and the method for making concrete.
But before doing that, we need an introduction and overview. How would you write these two paragraphs?
