AbstractTwo samples of Portland cement (Type I) containing different amounts of C[3]S, C[2]S, C[3]A and C[4]AF were mixed with constant proportions of hydrated lime and limestone, formed into discs of 3.18 cm diameter at a pressure of 9000 kg, and autoclaved at 1.03 MPa. One cement mixture showed significantly greater expansion than the other. The major cause of this difference was the formation of a stronger matrix in one mix, which exhibited smaller expansion. The nature of the calcium silicate hydrate and possible interaction of the aluminate and silicate phases with lime, calcium carbonate, and sulphate seemed to influence the type of matrix formed.
