I hired a concrete contractor to lay some concrete blocks and frame a window
opening. In the process of mixing/pouring/forming the concrete, he spilled
quite a bit of concrete onto my deck which is red brick with black grout.
Now I have a thin layer of concrete on top of my deck about 40 square foot
or so. I mentioned it to him and he said I am responsible to prep the area
and I should know it's going to be messy.

I tried to scape it off and it's not coming off. I don't know if there is a
tool to chip them out or am I stucked with replacing my entire deck if I
can't find 40SF of matching bricks.

The standard way to remove the top layer of concrete from
concrete is via shot blasting. This might work for you.

Obviously it depends on the relative hardness and shot
resistance of the spilled concrete and the underlying
brick. Since the concrete is presumably quite young,
I think the brick wins. Clearly, you need to test a
small area first. You may be able to rent the equipment
and try it yourself. Or hire a professional (and hope
he's a lot better than the last one).

Oh, the shot blaster may blast away a whole ton of
grout, esp. if it's soft. But regrouting would be a
small task compared to a brand new deck.

FYI: your concrete contractor is a serious a**hole and
if I were you, I'd consider filing a complaint with
the applicable licensing board and in small claims
court too.
