Definitions
- the present invention patent deals with a method of production of activated/calcined clay with calcium aluminoferrite or calcium ferrite and clay composition obtained by the aforementioned method, more precisely belonging to the field of production of cementitious materials where said method reveals a formation process of calcium aluminoferrite or calcium ferrite (in the form of Brownmillerite, for example) in-situ to obtain an activated/calcined clay from red clay that is acceptable to be added to cement.
- Clays with potential cementitious properties often called artificial pozzolanic clays or with pozzolanic activity when activated/calcined in a rotary kiln under normal operating conditions, generates a good quality activated/calcined clay.
- artificial pozzolanic clays or with pozzolanic activity when activated/calcined in a rotary kiln under normal operating conditions, generates a good quality activated/calcined clay.
- its red color significantly affects the color of the cement when this material is used as an additive.
- the clay is calcined pure, the calcining temperature of the material does not exceed 900°C, generating a red activated/calcined clay that, when added to the clinker, changes its color to reddish, causing consumer rejection of use and even distrust of the product's quality. It is noteworthy that the quality of the product is not compromised, but there is a custom regarding the color of the cement.
- WO12142547 discloses a cementitious composition including: a binder containing (a) 60-94% by weight of at least one pozzolanic material; (b) at least 0.5% calcium sulfoaluminate (CSA), by weight; (c) 1.2-11% by weight, expressed as SO 3 , of at least one inorganic sulfate selected from the group of sulfates consisting of a calcium sulfate hemihydrate, an anhydrous calcium sulfate, a calcium sulfate dihydrate, a sodium sulfate and a sodium calcium sulfate; and (d) a total sulfate content of at least 3% by weight, expressed as SO3, the cementitious composition including not more than 3% natural lime, the cementitious composition including not more than 10% alumina cement , the grades of the composition being calculated on a dry, non-aggregated basis.
- CSA calcium sulfoaluminate
- the present invention enables the use of red clays, notably those whose Fe2O3 content exceeds 4% by mass, until then an abundant and easily accessible reserve, underutilized for the manufacture of activated/calcined clay.
- the reservations of Clays are widely dispersed and available worldwide, including in limestone deposits.
- the applicant has found, surprisingly and unexpectedly, that the composition is capable of promoting such benefits, and, in particular, producing a colored activated/calcined clay suitable for use in cements.
- Another objective of this invention is to present a method of obtaining activated/calcined clay composition with calcium aluminoferrite or calcium ferrite that allows the use of red clay by modifying its color in the calcination from reddish to grayish.
- Another objective of this invention is to present an activated/calcined clay composition
- an activated/calcined clay composition comprising calcium aluminoferrite, preferably a calcium aluminoferrite or calcium ferrite resulting from 'in-situ' formation during calcination.
- This invention also deals with presenting an activated/calcined clay composition of grayish color derived from red clay as a raw material that allows use in cements, free from substantial color deviations.
- Figure 4 shows a graph of X-ray diffraction patterns of calcium ferrites prepared from the mixture of CaO and Fe2Ü3 with a Ca / Fe ratio between 0.33 and 3 by mass.
- the present invention patent refers to the "PRODUCTION METHOD OF ACTIVATED/CALCITED CLAY WITH CALCIUM ALUMINOFERRITE OR CALCIUM FERRIT AND CLAY COMPOSITION OBTAINED BY THE METHOD", more precisely it is a method of obtaining activated/calcined clay composition with calcium aluminoferrite or calcium ferrite and obtained clay composition.
- the method of obtaining activated/calcined clay composition includes the 'in-situ' generation of calcium aluminoferrite or calcium ferrite for color correction of activated clay. This method is presented as an alternative to traditional color control methods.
- the modification of the color of the red clay carried out in the activation / calcination step by the 'in-situ' generation method of calcium aluminoferrite or calcium ferrite is achieved by combining raw material for cement manufacture in the basic phase of clinker manufacture for cement, notably limestone and/or clinker flour, similar sources of calcium oxide, and red clay calcined in an activated/calcined clay oven at a temperature above 900 °C.
- the addition of 1 kilo of this typical raw material for the manufacture of cement clinker to the system corresponds to the addition of 432 grams of CaO.
- the stoichiometric ratio is 2:1, requiring two moles of CaO to react with one mole of Fe 2 O 3 .
- the molar mass of CaO is considered to be approximately 56.1 g/mol and the molar mass of Fe 2 O 3 to be approximately 159.6 g/mol.
- the estimated yield (75%) 112.2 grams of CaO and 159.6 grams of Fe 2 O 3 are needed to produce 203.8 grams of Ca 2 Fe 2 0s.
- the main parameter that leads to the formation of one product over the other is the Ca/Fe ratio.
- Hirabayashi, et. al. (2006) that the increase of the Ca/Fe ratio until 3 culminates in the increase of the reaction yield, to guarantee the economy of the activated/calcined clay produced we indicate only the addition of "typical raw material for the manufacture of clinker for cement" until maintain the stoichiometric relationship of the reaction (1).
- the clay composition obtained is activated/calcined comprising calcium aluminoferrite or calcium ferrite, preferably a calcium aluminoferrite or calcium ferrite resulting from 'in-situ' formation during calcination.
- the activated/calcined clay of the present invention has a greenish gray or brown color, which allows its use in cements, free from substantial color deviations.
