Influence of the amount of gypsum and curing conditions on the strength of composite Portland cements with carbonate-containing additives

The effect of curing conditions and the amount of gypsum as part of composite cements with carbonatecontaining additives on their strength was examined. It is shown that the best results are achieved with the hardening of cements under normal conditions. With high-temperature steam curing the strength decreases, but in the next 27 days of curing the strength increases to the desired value. Reducing the amount of gypsum in cement by 50% also reduces the strength, particularly in the steaming conditions.
