Concrete mix for shed base

by EdwardH
(Nottingham)

Morning All,


I'm looking to find out what mix of concrete and ballast I need for the base foundation of my 4m x 4m log cabin.
The concrete will be reinforced with a metal grid.

I am told the standard is 5 to 1, what would you advise?

Thanks

Using ballast for shed base concrete
by: John

Hi Edward,

DIY concrete is generally mixed by volume and comprises 1 part cement, 2 parts sand and 3 parts coarse aggregate.

As you are using ballast which is a mixture of sand and coarse aggregate then the ratio of 1 part cement to 5 parts ballast is correct.

To get a good strong mix don’t go to heavy on the water.

Regards

John
