The article discusses the use of magnesium oxide-based shrinkage-compensating concrete (MgO concrete) in construction of roller-compacted concrete (RCC) dams. The delayed autogenous expansion of MgO concrete roughly matches the shrinking process of dam mass concrete as its temperature drops and helps to prevent thermal cracking. Using MgO concrete in RCC dams can result in simplification of temperature control measures as well as shorten the construction period.
