SECAR 41 is a hydraulic binder with an alumina content of approximately 47% and an iron oxide content of approximately 5%. [It] is composed mainly of calcium aluminate phases, which makes it an ideal binder for refractory applications. SECAR 41 is particularly rich in monocalcium aluminate ... which imparts excellent properties to mortars and concretes.

CONT

The most important cement compounds formed on fusion are monocalcium aluminate(CA) and tricalcium pentaluminate(C3A5) ;furthermore, some pentacalcium pentaluminate and small amounts of dicalcium aluminosilicate, dicalcium silicate, and tetracalcium aluminoferrite are also present. Both monocalcium aluminate and tricalcium pentaluminate hydrate initially to a gel CaAl2(OH) 8·6H2O, which gradually changes to a very stable, crystalline complex Ca3Al2(OH) 10·3H2O and a gel of aluminium hydroxide Al(OH) 3.

Using a novel experimental procedure in the field of ceramics/materials science that is based on the precise microanalysis (scanning electron microscopy, coupled with wavelength-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compatibility relations in the subsystem ... were established. ... The temperature, composition, and character of the ternary invariant points of the subsystem were established, and the ranges of the solid solutions in periclase, spinel, monocalcium aluminate, and dicalcium aluminate also were studied and determined, up to 1725°C.

CONT

When limestones containing silica and clay are burned, the clay decomposes at between 400°C to 600°C and combines at 950°C to 1250°C(the top end of the burning temperatures for hydraulic lime : sintering takes place at 1300°C to 1400°C) with some of the lime, forming silicates and aluminates, especially tricalcium silicate and dicalcium aluminate.

OBS

Les composés principaux formés dans les scories de ciment Portland et qui confèrent les propriétés de liaisonnement et de résistance, sont les silicates de calcium, 3CaO.SiO2 et 2CaO.SiO2. Lorsqu'on les mélange avec l'eau, ces composés anhydres s'hydratent, se prennent, et durcissent lentement en suivant le comportement bien connu du ciment Portland. L'aluminate tricalcique 3CaO.Al2O3, qui se trouve dans les scories, forme aussi un hydrate avec l'eau; [...]
