Portland Cement Phases: Polymorphism, Solid Solution, Defect Structure and Hydraulicity

“…The morphologies of the C-S-H formed during hydration of these polymorphs were found to be different. The cubic phase of C3A (Pure) hydrates faster than the polymorphic forms of C3A (stabilized with foreign ions) [31]. The higher reactivity of pure C3A in this case can be related to structural aspects.…”

“…The crystallization of C3A phase in Portland cement is a function of the chemical composition of the raw materials, of the reaction of the combustible, and of the process used in the cooling of clinker. C3A can be cubic, orthorhombic, but rarely monoclinic in commercial clinker [31].…”
