    In order to study the structural and hydration properties of Low Heat Portland Cement (LHPC), X-ray powder diffraction (XPD) and quasi-elastic neutron scattering (QENS) experiments were performed. In the Rietveld refinement of LHPC, it was validated that the principal component of LHPC is Ca2SiO4 of which structure has the monoclinic beta-phase. The QENS experiments showed the hydration behavior of LHPC; three different stages (induction period, nucleation and growth period and diffusion-limited period) are clearly observed in the bound water index (BWI) as a function of hydration time. Moreover, the initial hydration process of LHPC could be described by a four-parameter equation based on the Avrami model.
