Descrição
Resumo:[EN]The carbonation process of aluminous cement in presence of high alkali content is studied. In this work, the formation of a compound which formula is close to K^Al/COJjjJOH)JHp) is shown for the studies samples. The aluminous cement carbonation in alkali presence take place, at least, in two stages. In a first stage the aluminium and potassium carbonate hydrate joint to CaCO^ is formed. Later, that aluminium potassium carbonate hydrate is developed toward the aluminium hydroxide formation.
