Hello,
I am building a garden room 7.4m x 3.7m garden room on 15, 20cm x 40cm x 40cm concrete footings that I have made formwork for. I will also be putting 8mm stainless steel rebar in them as they are quite thick at 20cm. Everything is set in place, levelled, placed on Mot type 1 and ready to be filled.
I was going to use Blue Circle or Breedons C40 pre mixed bagged concrete, but decided to go for Breedons high strength 52.5N cement instead, to mix with my own ballast as there was a price difference of about £250 between pre mix C40 and mixing my own "high strength concrete".
I called Breedon twice to ask about mix ratios for this product for my application and in all honesty I had more chance of getting blood from a stone than getting an answer from the person I got put through to. She just seemed keen to get me off the phone and not willing to enquire further. Just all our info is on our website type of thing!
I also asked at builders depot where I bought it from and nobody I spoke to really knew.
The back of the packet doesn't really state anything for mix ratios either.
Here is a link to the product:
https://www.builderdepot.co.uk/breedon-high-strength-cement-25kg
So I have come here in the hope to seek some advice...
So if anyone has any solid advice about cement to ballast ratio for my application with this type of product I am all ears.. well eyes so to speak.. ha
Thanks,
Antony
