Hi all,
I'm trying to find methods or advice for mix design focused on the next day strength. Our concrete needs to be a C28 strength in about 18 hours so the beds can be detensioned and stripped. I'm working on what proportion of GGBS I could possibly aim to include but want to do some mix designs before starting testing. I'm aware that the high early strength requirement is not going to be easy with GGBS but want to have a place to start and something to put some numbers to.
Kind regards,
Matt
