I was wondering if someone would submit an image of actual fresh concrete or a concrete mixer. It happens that there are several. I like the idea. Not very fond of the photographic execution, but bold idea, nevertheless.
Is this the best that you could do for this topic? The bright lights are a distraction and while it looks like there is a pile of concrete behind the fence, I can't really tell. Then it is just about trucks sitting on concrete. Not a good composition. Keep trying though.
