The structure of C-S-H
Języki publikacji
Podano przegląd modeli opisujących zmiany struktury C-S-H w ujęciu krystalochemicznym w zależności od składu wyrażonego stosunkiem wapnia do krzemu, który jest wyznaczony przez skład roztworu wypełniającego pory. Porównano różne modele i omówiono je w świetle ostatnich wyników uzyskanych za pomocą najnowszych metod badawczych, takich jak mikroskopia sił atomowych i dwuwymiarowa spektroskopia za pomocą magnetycznego rezonansu jądrowego. Omówiono charakter żelu C-S-H w zaczynie cementowym i jego krystaliczność.
The paper reviews the models describing the structural evolution of C-S-H at the crystal-chemical level as a function of composition in terms of calcium to silicon ratio which is fixed by the pore solution composition. The different models are compared and discussed in the light of recent data obtained by new investigation techniques like Atomic Force Microscopy and two dimensional Nuclear Magnetic Resonance spectroscopy. The nature of the C-S-H gel in a cement paste and its crystallinity are discussed.
