Concrete that very likely would pass inspection

20-6-2014Concrete that very likely would pass inspection Discussion in 'Building' started by richard7761 I'm not actually sure there is a best as such Maybe there is just concrete mix for footings ( I think 1 6 using all-in ballast) It is less easy (I presume) to get the cement to water ratio correct The concrete though should be a dry mix Get price

Mix ratio of C40 concrete

3-9-2019The reason you can't find a prescribed mix ratio for C40 is it doesn't exist BS5328 only goes up to 25N and anything above 20N can't be mixed with all in ballast That's not to say you couldn't end up with a mix higher than 25N - just that it's not predictable based on the mix ratio The only way to guarantee 40N is readymix Get price
