Title (EN) RAPID HARDENING, ULTRA-HIGH EARLY STRENGTH PORTLAND-TYPE CEMENT COMPOSITIONS, NOVEL CLINKERS AND METHODS FOR THEIR MANUFACTURE
(FR) COMPOSITIONS DE CIMENT DE TYPE PORTLAND A PRISE ULTRA-RAPIDE ET A TRES HAUTE RESISTANCE INITIALE, NOUVEAUX CLINKERS ET LEURS PROCEDES DE FABRICATION
Abstract: front page image
(EN)Clinkered materials containing high concentrations of {(C,K,N,M)¿4? (A,F,Mn,P,T,S)¿3? C1, S)} (crystal X), and {C¿2?S)¿3? (CS)¿3? C(f,C1)} or C¿10?S¿3?S¿3?(f,c1) (crystal Y), and/or {C¿5?S¿2?S) (crystal Z). The methods include the steps of forming a mixture of raw material containing CaO, MgO, A1¿2?O¿3?, Fe¿2?O¿3?, TiO¿2?, Mn¿2?O¿5?, SiO¿2?, SO¿3?, Na¿2?O, K¿2?O, P¿2?O¿5? and F, respectively designated C, M, A, F, T, Mn, S, S, N, K, P and f, and heating said mixture to an elevated temperature between 900 °C and 1,200 °C. Final mixtures comprising these clinkers and hydraulic or portland type cement are made to produce cement compositions having crystal X concentrations of approximately 5 % to 35 % by weight, crystal Y concentrations of approximately 5 % to 40 % by weight, and/or crystal Z concentrations of approximately 5 % to 40 % by weight, with the remainder being hydraulic or portland type cement.
(FR)Cette invention concerne des matériaux de cuisson renfermant des teneurs élevées en {(C,K,N,M)¿4? (A,F,Mn,P,T,S)¿3? C1, S)} (cristal X), et {C¿2?S)¿3? (CS)¿3? C(f,C1)} ou C¿10?S¿3?S¿3?(f,c1) (cristal Y), et/ou {C¿5?S¿2?S) (cristal Z). Ces procédés consistent à former un mélange de matière première contenant les composés CaO, MgO, A1¿2?O¿3?, Fe¿2?O¿3?, TiO¿2?, Mn¿2?O¿5?, SiO¿2?, SO¿3?, Na¿2?O, K¿2?O, P¿2?O¿5? et F, respectivement désignés par les lettres C, M, A, F, T, Mn, S, S, N, K, P et f, et à chauffer ledit mélange à haute température entre 900 °C et 1,200 °C. Les mélanges finaux renfermant ces produits de cuisson partielle et du ciment de type hydraulique ou portland permettent d'obtenir des compositions de ciment caractérisées par des concentrations,en poids de 5 à 35 % environ pour le cristal X. de 5 à 40 % environ pour le cristal Y et/ou de 5 à 40 % environ pour le cristal Z, la partie restante étant constituée par du ciment hydraulique ou portland.
