This MP Rapid Set stuff is magic - its made by Blue Circle Southern, uses NO portland cement, dries smooth and off-white and sets in about 15-20mins, 4MpA in 1 hr, 7MpA in 24hrs. It's based on advanced magnesium phosphate cement technology (aka CeMag / Magna crete). It's not cheap but its less than 10% of the cost of epoxy for the same job.

Subject: Crack sealing repair of Concrete footpaths
Is there a product, preferably not black, that provides an economic and pedestrian friendly sealing of cracks/gaps 5 - 30mm? Current practice is to use Degacote (epoxy mix cement-like filler) or 7mm asphalt. With a 1600km network there are many km of broken and displaced concrete.
