Concrete歌词完整版
Concrete—it’s everywhere, From big skyscrapers in the air
To sidewalks underneath our feet
But tell me, how do you make concrete?
Now, concrete’s not cement, but...
Cement’s an ingredient!
It’s crushed up limestone, sand and clay
And even some shells (yea, it’s made that way!)
And another ingredient
Is a thing that we call aggregate
It just means a bunch of loose rocks and stuff— Yeah,
stones that are small but tough!
You need some coarse aggregate like gravel or rocks To make concrete strong in walls and blocks
And you need a fine one too,
To fill the little gaps for you
Water turns the cement to goo
That holds aggregate together like glue Then put it where it’s supposed to be, And let it harden naturally!
Concrete—it’s everywhere,
From big skyscrapers in the air
To driveways, columns, bridges, dams
That’s the end of our concrete jam!
