Blue Circle Mastercrete and how much of it

Question

Hi, I'm building block paved area in the garden, and trying to plan it out first. I usually put a layer of concrete before motaring the bricks on, but the diy place i go to get the concrete has no concrete but has only got Blue Circle Mastercrete. Can that be used in the same way, and how much would a 25kg bag cover?

thanks

Answer 1

Dazman has a 25Kg shovel!  I would think 4 to 1 a bit strong.

Wickes probably have a leaflet, can endorse paving expert.

By the way Mastercrete is OPC in a plastic bag,

Answer 3

you should use a 7:1 mix - 4:1 is far too strong & also expensive.

You should bed your slabs/blocks on about three inches of compacted mix. Good idea to hire a wacker plate.  

Answer 4

yes that would be fine .

Mixing it at 4 and 1 (4 sand & 1 Cement) would get you a good couple of barrow fulls of mix.

you just about get 4 shovel fulls of cement to a 25kg bag
