Procède pour l'amélioration et l'accroissement des proprité des agents.
On sait que le durcissement des ciments à pris e lente ou rapide(portland,la iti er,alumineux,pouzz olane)pr oviont des différentes réactions qui accompagnent les phénomènes de prise et qu'il y a intérêt à ce que cette réaction ne soit pas ex- trèmement lent e car, en pratique, elle deviendrait. Inutilisable.
On sait notamment,que pour accélérer la réaction, on emploie couramment,dans le ciment de laitier,du. carbonate de sodium, et dans le ciment artificiel, du chlorure de calcium.
Les différentes réactions qui doivent amener les phénomènes de aristallisation sont,d'ailleurs,amorcées par certains pro- duits qui,ajoutés à la chaux, produisent des accélérations de réactin,tels sont les sulfates de chaux et les carbonates et sulfat es alcalins.
Maigre ces différents produits,les ciments de toutes les catégories donnant, en mortier plastique des résistances qui,
<Desc/Clms Page number 2>
bien, que voisines,sont classables par origines ou familles.
En outre,dans les procédés usuels de fusion du ciment, les oxydes de fer, normalement contenus dans la matière bru.te,sont réduits par la température de fizsion qui règne dans les fours.
La présente invention a pour objet l'incorporation dans les ciments, soit au cours de leur fabrication,soit au moment de leur emploi,d'oxydes métalliques,comme les oxydes de fer, 2 2 2 8, 3 4 2 3 2 Fe O,Fe 0 , Fe 0 Fe 0 ,-d'aluminium,Al 0 ,d'étain,Sn 0 ,
2 de manganèse,Mn O,Mn 0 , etc* etc.....
-oette incororation consistant en 1' Emploi d'un seul de cas oxydee, ou en un mé- lange de plusieurs d'entre eux,c'est ainsi que l'oxyde fer
2 3 rique Fe 0 à l'état de poudre impalpable,mél angé à l'oxyde ferreux Fe 0,se combinera en un oxyde intermédiaire, ou oxyde magnétique,-et ce sera alors cet oxyde magnétique qui amor- cera la réaction recherchée.
Ces oxydes qui resteront stables dans la masse pulvéru- lente se transformeront en catalyseur, dès qu'ils seront en présence de l'oxyde d'hydrogène qui sera utilisé pour la confection du mortier, en lui procurant un durcissement plus rapide et en lui communiquant,par la suite,des résistances insoupçonnées et nullement comparables aux résistances actuel- lement connues tant à la compression,la perméabilité,la des- tructin. et la décomposation L'accélération ainsi obtenue permettra,notamment dans l'emploi du ciment armé,un décoffrage plus rapide ce qui représaltéra une diminution notable des dopons es de mat ériel.
Enfin,ces oxydes qui seront incorporés aux ciments, per- mettront à ces derniers,quelle que soit leur classé(artifi- ciel,laitier, etc... etc.. )de posséder des résistances sem- blables,presque identiques,dans tous les domaines et de former ainsi une nouvelle famille, celle des Ciments oxydés,,*

Proceeds for the improvement and the increase of the properties of the agents.
We know that the hardening of cements with slow or fast setting (portland, iti er, aluminous, pozz olane) pr oviont the various reactions which accompany the setting phenomena and that it is advantageous that this reaction is not not extremely slow because, in practice, it would become. Unusable.
It is known in particular that, in order to accelerate the reaction, is commonly used, in slag cement,. sodium carbonate, and in artificial cement, calcium chloride.
The various reactions which must bring about the phenomena of aristallization are, moreover, initiated by certain products which, added to the lime, produce accelerations of reactin, such as lime sulphates and alkaline carbonates and sulphates.
Lean these different products, the cements of all categories giving, in plastic mortar resistances which,
<Desc / Clms Page number 2>
well, that neighbors, are classifiable by origins or families.
In addition, in the usual cement melting processes, the iron oxides, normally contained in the raw material, are reduced by the fizsion temperature which prevails in the furnaces.
The present invention relates to the incorporation into cements, either during their manufacture or at the time of their use, of metal oxides, such as iron oxides, 2 2 2 8, 3 4 2 3 2 Fe O , Fe 0, Fe 0 Fe 0, -aluminum, Al 0, tin, Sn 0,
2 manganese, Mn O, Mn 0, etc * etc .....
This incororation consisting of the use of only one of the oxidized cases, or of a mixture of several of them, for example iron oxide.
2 3 ric Fe 0 in the state of impalpable powder, mixed with ferrous oxide Fe 0, will combine into an intermediate oxide, or magnetic oxide, and it will then be this magnetic oxide which will initiate the desired reaction.
These oxides, which will remain stable in the pulverulent mass, will transform into a catalyst, as soon as they are in the presence of the hydrogen oxide which will be used for making the mortar, giving it a more rapid hardening and giving it , thereafter, unsuspected resistances and in no way comparable to the currently known resistances both to compression, permeability and destruction. and decomposition The acceleration thus obtained will make it possible, in particular in the use of reinforced cement, to remove the formwork more quickly, which will represent a notable reduction in the dopons of the material.
Finally, these oxides which will be incorporated into the cements, will allow the latter, whatever their classification (artificial, slag, etc ... etc ..) to have similar resistances, almost identical, in all domains and thus form a new family, that of Oxidized Cements, *
