How to prepare C35 and C10 concrete?

Question

hi,

any one know the combination for c35 and c10 concrete (how much of each ingredient and what it is (eg sand,cement etc.))

Answer 1

to mix these types you won't be able to do it by hand. they need to be mixed at a concrete plant in a hopper. as they contain a extra product called slag.

Answer 2

Rat is right these are not mixes you can do in a small mixer or by hand.

I assume as you have the C numbers you are planning some home improvment which requires specific concrete mixes such as an extension.

If this is correct then you need to get a concrete company in to supply it for you and provide you with a quality certificate which will be required by the building inspector

There are a load of additives you can include with concretes such as slag, fiber, feathers, poly beads, hessian, not to mention the chemical additives
