Now that's an impressive amount of cement......
Concrete.....cement is a powder like binder, forming part of the concrete mix (including, but not restricted to water, sand and aggregate)
but was the truck full or empty? What was its GWVM?....oh and lots of tyres help reduce ground pressure. Infact you could probably run a 60 tonne tank over a paddle blade (approx half the ground pressure of a car!)
