ANALYSIS OF CALCIUM ALUMINATE CEMENT PASTES [PDF]
, 2020 In this research different formulations of calcium aluminate cement pastes (CACP) with 71wt% Al2O3 (CACP 71wt%), (wt% -percentage by weight) were made, at 0.4 water to cement ratios (W/C), with additions of 0wt%, 10wt% and 20wt% of silica (CACP 71-0wt%, 10wt% and 20wt%, respectively).

Minerals of expansive and non-shrinkage sulfomineral cements
MATEC Web of Conferences, 2017 Usually to obtain expansive cements sulfoaluminate clinker or mix aluminate clinker with calcium sulfates (gypsum, hemihydrate, anhydrate) are used. For these cements ettringite is an important hydration product and kinetic reaction of this phase plays ...

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process
steel research international, EarlyView.This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.
