This monograph describes cement clinker formation. It covers multicomponent structures, clinker section constructions and their reactions with water, hydrate composition and constitution, in addition to their actual houses. The mineral additions to cement are defined as are their impact on cement-paste homes. certain cements also are mentioned. The microstructure of concrete is then provided, and specific emphasis is given to the position of the interfacial transition sector, and the corrosion procedures within the gentle of cement-phase composition, mineral additions and w/c ratio. The admixtures' function in glossy concrete expertise is defined with an emphasis on superplasticizer chemistry and its cement-paste rheological amendment mechanism. Cement with bizarre houses, resembling calcium aluminate, white, low power and expansive cements are characterised. The final a part of the publication is dedicated to important varieties of concrete equivalent to self compacting and to reactive powders.

In this later case in the solid phase exists CaO when ferrite starts to crystallize and contains less Al2O3 than C4AF, then the C3A will be formed. The calculation according the Bogue’s method will give too low content of C3A and to high of ferrite phase. 84. For higher value of alumina ratio small quantity of C3A will crystallize and the ferrite phase will be richer in alumina than C4AF. In this case the calculation according to Bogue’s formulae will give too high C3A content and too low ferrite phase.

Frequently of very disturbed constitution. Maki [42] distinguishes two periods of alite crystals growth: quick and in condition close to equilibrium. The crystals formed during the quick growth period contains the inclusions of liquid phase. They are usually in the core of crystals. In the similar conditions the inclusions of small crystals of C2S and CaO as well as air bubbles can be formed. 6 Al2O3+Fe2O3, % Fig. 0 a result of mechanical vibrations, caused by kiln rotations. The extended period of rapid growth gives very disturbed crystals, mostly without regular faces.
