Effect of alkalies on portland cement hydration
I. Alkali oxides incorporated into the crystalline lattice of clinker minerals
AbstractNa2O and K2O in absence of SO3 are incorporated preferentially into the C3A phase of portland clinker altering its modification from cubic to orthorhombic. The hydration of Na2O doped C3A is retarded and that of K2O doped C3A accelerated in the resultant cements. The progress of C3S hydration and strength development are not altered noticeably. The setting time is extended in Na2O-doped and shortened in K2O-doped cements.
