Cu can lower the rate of hydration of cement pastes including C 3 A by forming some protective layers on the unhydrated cement minerals [ 16 – 18 ]. The retardation of cementhydration is also dependent on the solubilities of the protective layer

The microstructure of the mortar from the 1950’s building is shown in Fig. 8 . The matrix (M) in the machine-mixed mortar is a uniform composition of cementhydrates and carbonated lime surrounding sand
] on the behavior of SF on the steel slag powdered concrete, a decline in the CS was observed beyond 8% of addition of SF, which is due to the fact that Ca(OH) 2 produced upon cementhydration was exhausted as a result of which no C–S–H gel could be
analysis of the concrete structure, the numerical strategies are implemented considering the cementhydration, creep, shrinkage, and solar radiation for early age concrete. The objective is to document and hopefully verify a method of thermal analysis and
