I’m trying to understand what are the implications of specifying lower carbon concrete and would appreciate any insights to this. Ideally, I want to be in a position to spec a certain % of cement replacements in a mix and give a rough idea of what the cost implications are and what the impact may be on the curing times. This is vital information to get the contractor on board but I’ve not found they as willing to do the research.
Has anyone put together a table similar to the one below? This CO2 saving is a rough calc based on the CRMCA EPD. And the cost implications I’ve made up. It would also be good to add other proprietary mixes or alternative options that could be considered (maybe adding limitations and/or locations available columns?)
