Abstract


Research to overcome the nature of false set in white Portland cement using ground granulated blast furnace slag (GBBFS) was carried out by mixing white Portland cement, which experienced false sets, with GBBFS. The addition of GBBFS to the GBBFS-cement mixture is 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60% and 70%. Whiteness test and false set results show that the addition of GBBFS will reduce the whiteness of the mixture to 80% by 42% of GBBFS, while the addition of 6% of GBBFS will begin to overcome the problem of false set of white-GBBFS cement mixture, but other considerations due to white cement specifications must be considered to keep white cement meeting standard specifications.
