These lectures present the formation and the phase composition of portland cement clinker and the regularities when show binding properties. The influences of the structure, the ratio between solid and liquid phase, temperature, pressure and the additions on the hydration activity of clinker phases are studied.
The properties of dispersed hydrate products, aggregate resistance and coagulation of portland cement disperse systems and physical structure of portland cement dough are discussed. The formation of rock like cement is connected with the crystal chemistry of hydrated products and possibilities to activate and control the process of hardening. Special attention is paid to the different kinds of corrosion and the methods to save the stability of harden cement.
