In tests conducted on blended Type K expansive cements, it was observed that in fine blends, the main expanding particles (C4A3~) and sulfates deplete faster compared to identical coarser blends because the fine blends have a larger number of expansive sites. This can decrease the expansion time and

## ABsmcT On 20 cement pastes made from cements of variable C3A and SO3 contents and cured at different curing conditions the effect of cement composition on the extent of expansion was studied. It appears that the extent of the generated expansion depends especially on the C3A and SO3 contents in

The hydration and setting time of MgO-type expansive cement was investigated. The results show that the addition of MgO retards the initial hydration of the cements and increases the setting time. The causes for the retardation of hydration can be attributed to: (1) since the solubility product cons
