Cement Mix for Pavements

[borge14]

Hi,

I need to mix 2.5 cubic metres of cement for an area of pavement around my house. Does anyone have any idea approximately how many bags of cement I will need and how much sand? I appreciate this may be a 'how long is a piece of string' question, but I just need a rough idea so I can work out cost. Ultimately I need to know whether it is more cost effective to do it this way (albeit more time consuming), or should I simply buy in some ready mix? I am on a v tight budget!

Thanks,
George

2.5 m3 of concrete will use about 4 tonnes of sand and gravel (ballast) with about 26 bags of cement.

mix it at 6 ballast to 1 cement. the ballast should be at a ratio of 4 gravel or aggregate to 2 sharp sand. the ballast though, should arrive already mixed.
