Tricalcium aluminate (C3A) is a major phase of Portland cement clinker and some dental root filling cements. An accurate all-atom force field is introduced to examine structural, surface, and hydration properties as well as organic interfaces to overcome challenges using current laboratory instrumentation. Molecular dynamics simulation demonstrates excellent agreement of computed structural, th...

The study reported herein indicated the stabilization mechanisms at work when copper-laden sludge is thermally treated with gamma-alumina and kaolinite precursors, and evaluated the prolonged leachability of their product phases. Four copper-containing phases - copper oxide (CuO), cuprous oxide (Cu(2)O), copper aluminate spinel (CuAl(2)O(4)), and cuprous aluminate delafossite (CuAlO(2)) - were ...

In this study, the evaluation of aluminium dross from secondary production in calcium aluminate cement was investigated. Salt compounds were removed significantly by washing. Mixtures washed and quicklime prepared to obtain a additive considering standard with low alumina they sintered at 1250 °C for 5 h. The phases mayenite, monocalcium aluminate, grossite, gehlenite, larnite, periclase spinel...
