Acid will struggle to move really heavy stuff. You could try loosening the surface of the cement by tapping it gently with a hammer. The acid might then have a better chance.

Also, the acid in DIY stores today is very weak stuff. I have half a gallon of acid in my garage which I've had for 15 years or so and that would dissolve the wall if you left it on long enough.
