Removing cement from a block paved drive

Not really a plumbing problem, but whilst fitting a boiler I spilled some cement onto a block paved drive.
I've tried hosing it down and brushing it off, but not much luck.
Any advice chaps?

Scrubbing with a wire brush may remove

Along with simple brushing, the occasional scrub down soapy water can work wonders! Washing up liquid is the best to use but you can use certain floor cleaners, just make sure that they are acid free as acid based cleaners can react and damage some concrete or stone surfaces.

This method simply involves a bucket, some water, a brush and your chosen soapy cleaner. Using either hot or cold water, fill up your bucket and mix in your soap solution and then chuck some over a small area (work in small areas at a time).
