Procedimiento y aditivo para el aumento de la resistencia inicial y empleo del aditivo
Procedimiento para la aceleración del endurecimiento de agentes aglutinantes hidráulicos o hidráulicos de manera latente, caracterizado por que al agente aglutinante se añaden ternesita y un componente de aluminio reactivo no hidráulicamente, seleccionado a partir de compuestos de aluminio convenientemente hidrosolubles y aquellos que tienen una solubilidad apenas reducida, pero desarrollándose el proceso de disolución tan rápidamente que se se proporciona alumino en la medida de su transformación.
Binder comprises 20-95 wt.% of Portland cement and 5-80 wt.% of ternesite cement, where ternesite cement comprises 20-100 wt.% of the clinker phase containing sulfospurrite and another clinker phases, and the another clinker phase comprises 0-80 wt.% of (alpha ,beta ) dicalcium silicate (AA), 0 wt.% to less than 15 wt.% of fluorinated compound (BB), 0-30 wt.% of another fluorinated compound (CC), 0-20 wt.% of reactive aluminates, 0-25 wt.% of periclase and 0-30 wt.% of secondary phases. Binder comprises 20-95 wt.% of Portland cement and 5-80 wt.% of ternesite cement, where ternesite cement comprises 20-100 wt.% of the clinker phase containing sulfospurrite and another clinker phases, and the another clinker phase comprises 0-80 wt.% of (alpha ,beta ) dicalcium silicate (AA), 0 wt.% to less than 15 wt.% of a fluorinated compound of formula (C 4(A) x(F 1 - x) 3) (BB), 0-30 wt.% of another fluorinated compound of formula (C 2(A yF 1 - y)) (CC), 0-20 wt.% of reactive aluminates, 0-25 wt.% of periclase and 0-30 wt.% of secondary phases. x : 0.1-1; and y : 0.2-0.8. Independent claims are included for: (1) the preparation of ternesite clinker comprising a raw mixture containing sintering at least one sources of calcium oxide, silica and sulfur trioxide, where the temperature of sintering is adjusted to 900-1300[deg] C such that the ternesite clinker comprises 20-100 wt.% of sulfospurrite and less than 15 wt.% of (AA); and (2) preparing the binder comprises mixing 5-80 wt.% of ternesite clinker or a cement and 20-95 wt.% of at least one Portland clinker or cement, where the amount of sulfospurrite in the binder is at least 5 wt.%.
