Abstract Recycled concrete powder (RCP) is used more and more in cement-based materials, but its influence on the
hydration process is still unclear. Therefore, this paper studied the influence of recycled concrete powder
(RCP) on the hydration process of cement and provides a theoretical basis for the hydration mechanism of
cement composite materials. The hydration heat method was used to systematically analyze the thermal evolution
process of cement paste with or without RCP. Hydration products were identified using X-ray diffraction (XRD)
and thermal analysis (TG–DSC). The pore structure change of cement pastes was analyzed by mercury intrusion
porosimetry (MIP) method. The… More >
