The paper investigates the heat formation and absorption processes in the cement-water system. The temperature gradient in a cement composition is one of the mainsprings of cement hydration and curing and the formation of final properties of the cement-water system. The differential calorimetric analysis based on measuring the temperature difference between dry and wet cement shows the reciprocal, cyclic heat formation. The observed effects are caused by the processes of dispersion and hydration of cement particles and crystallization of cement hydration products. Three types of harmonic frequencies are detected for the heat formation, viz. 1–3 vibrations per minute, ~12 h, and a several days vibration period. The heat formation-based analysis of phenomena observed in the cement-water system shows self-excited vibrations during the cement hydration and curing. The reaction continues owing to the energy release during hydration of clinker minerals and dispersion of the initial cement particles. The high sensitivity of the differential calorimetry as against the integral methods provides the deeper understanding of the phenomena observed and allows improving the cement potential in the production of a wide range of building materials.
