This experimental study revisits the hydration of Portland cement (PC) focusing on the internal changes in the material. For this, samples of cement mortar were prepared and placed in an X-Ray CT imagining setup. The tomographic scanning was performed during the 25-hour period of mortar hardening and hydration heat was measured additionally to the XCT imaging. Prior to the imaging procedure, the adiabatic hydration heat of studied mortar was measured while the chemical and mineralogical analysis of the used PC was determined.
