How much does a 'standard' 600mm x 900mm paving slab weigh
(approximately)? I want to know so I can guesstimate how many I can
put in the back of my car.

If you're talking about the pressed granite sort used by local authorities,
I always reckon that a 2x2 weighs a hundredweight, and a 3x2 a hundredweight
and a half.

On that basis, one of your 600x900 (nearly a 3x2) will be about 70Kg.

Not a bad estimate.

There is a table down towards the bottom of this page on Cormaic's
excellent site.:

http://www.pavingexpert.com/pccflag1.htm

It gives approx. weight for 600x900x50 mm flags of 64 kg.

All I know is if you are trying the lay the buggers, they are bloody
heavy, and hard work to lay if you've not had plenty of practise.
