The addition of copper slag in concrete increases the depth of carbonation but, the adding together fly ash for cement replacement decreases the depth of carbonation. Because, the fly ash reacts with the surplus lime, and gives additional C-S-H gel to concrete hence, reduces permeability and as a result, it improves the resistance …
