Low-lime saturated belite clinkers were prepared under different regimes of burning in the laboratory. Development of compressive strengths of the obtained belite clinkers was evaluated in relation to the reactivity of raw meals, burning temperature and time, and degree of lime saturation. Electron and optical microscopy, X-ray diffraction analysis and high-temperature microphotometry were the methods used for characterization of belite clinkers. It was discovered that the quickly-burnt belite clinker has unexpectedly lower hydraulic activity with respect to the longer-time burnt, recrystallized clinker. The reason could be little contamination of its crystal lattice by secondary oxides as determined by electron microanalysis.

Substitution by strontium induces significant oxygen deficiency in the crystal lattice of K2NiF4-type Nd2−xSrxNiO4−δ at elevated temperatures which, in combination with significant electronic conductivity, implies enhanced mixed ionic–electronic transport.
