Post-calcium Treatment Evolution of Alumina (Al2O3) Inclusions Morphology

The post-calcium morphological evolution of Al2O3 inclusions formed under high-oxygen supersaturation (~1000 ppm) was investigated through time-resolved sampling and quenching of aluminum-killed, calcium-treated steel.

Optimization of Soil Stabilization with Class C Fly Ash; HR-260 , January 1987 [PDF]

, 1987
Previous Iowa DOT sponsored research has shown that some Class C fly ashes are ementitious (because calcium is combined as calcium aluminates) while other Class C ashes containing similar amounts of elemental calcium are not (1).

New perspectives on calcium environments in inorganic materials containing calcium-oxygen bonds : a combined computational-experimental Ca-43 NMR approach

, 2008
The potential of a combined experimental-computational Ca-43 solid state NMR approach for the structural analysis of different families of inorganic compounds (calcium phosphates, silicates, aluminates and borates) has been investigated.

Study of the early hydration of calcium aluminates in the presence of different metallic salts [PDF]

, 2015
The effect of chlorides and nitrates of Li(I), Cr(III), Zn(II), Cu(II), Pb(II) nitrate and Cr(VI) (chromate) on the early hydration of ternary cement system of calcium aluminates (CA, CA2, C12A7) was reported.
