Definitions
- the present invention is part of the technical field of binder materials that use waste from the construction industry in their composition, more specifically it refers to a geopolymeric binder that uses demolition waste without adding Portland cement (hydraulic cement), it is used in the construction industry.
- the geopolymeric binder product is described, as well as the procedure for obtaining it.
- Portland cement is a binder or hydraulic cement that, when mixed with aggregates, water, and discontinuous and discrete steel fibers, has the property of forming a resistant and durable stone mass called concrete. It is the most common in construction and is used as a binder for the preparation of concrete (called concrete in various parts of Latin America).
- As hydraulic cement it has the property of setting and hardening in the presence of water, by chemically reacting with it to form a material with good binding properties. It was invented in 1824 in England by the builder Joseph Aspdin. The name is due to the similarity in appearance with the rocks found on the island of Portland, in the county of Dorset.
- Geopolymer is a term coined by Joseph Davidovits in the 1980s to designate inorganic synthetic polymers of aluminosilicates that come from the chemical reaction known as geopolymerization; however, these compounds had already been developed in the 1950s in the Soviet Union under the name of Soil cements. Geopolymers are also known as inorganic aluminosilicates.
- the present invention refers to a simple and easy-to-use methodology for obtaining geopolymeric binders from construction industry waste, specifically, ignimbrite rock waste, demolition mortar and calcined clay, without the addition of any other known binder (Portland cement, gypsum, clay, lime, pozzolan or fly ash) and having good mechanical properties in uniaxial compression.
- construction industry waste specifically, ignimbrite rock waste, demolition mortar and calcined clay
- any other known binder Portableland cement, gypsum, clay, lime, pozzolan or fly ash
- An additional technical advantage of the present invention is that, after having manufactured the geopolymeric binders, they were used to obtain geomortar mixtures, in the appropriate proportions of geopolymeric binder and fine sand (preferably, in a binder:fine sand mass ratio between 0.25 and 0.3). It is possible to obtain geomortars with average mechanical resistance of up to 58, 83 and 31 MPa, for geopolymeric binders derived from demolition mortar dust, calcined clay and Ignimbrite rock residues, respectively.
- the present invention is novel and unique because it includes the manufacture of geomortars which do not include coarse aggregates in their composition, unlike the geopolymeric concretes of the state of the art, which do include said coarse aggregates.
- fly ash, Portland cement or other known binders gypsum, lime, clay or pozzolan
- the proposed invention includes ignimbrite rock waste mixed with at least one of demolition mortar and calcined clay;
- these construction powders are mixed with an aqueous sodium hydroxide solution. They are the only components of the geopolymeric binder, which later gives rise to the manufactured geomortar, and is responsible for the cohesion/agglomeration action of aggregate particles.
- the present invention has been verified and validated in the mass ratios of:
- a rich source of aluminosilicates is obtained from demolition waste (demolition mortar, calcined clay or Ignimbrite rock waste), and a sodium hydroxide solution as a hardening solution; then an appropriate amount of fine sand is added to obtain the geomortar, as is done in obtaining traditional Portland cement mortars.
- the three types of raw materials of the binder (demolition mortar, calcined clay or Ignimbrite rock residues) are crushed separately, then fine manual grinding is carried out in an alumina mortar, followed by sifting of the ground materials, passing them through through a sieve between 75 to 106 microns.
- an activating alkaline solution is prepared, for which drinking water and sodium hydroxide (Na(OH)) pellets are mixed in a water:Na(OH) mass ratio, preferably between 1.7 and 2.1.
- This solution allows the amorphous compounds of silica and alumina, present in the raw binder material, to form interlinked 3D structures, which then have the potential to harden over time, similar to what occurs in the setting of Portland cement mortars. .
- Adequate quantities of activating solution and binder raw material powder are mixed in a solution:raw material mass ratio between 0.5 and 0.6, until forming a plastic, homogeneous and workable paste, which we will call geopolymeric binder.
- the geomortar paste obtained in the previous point is pressed uniaxially up to 60 to 100 MPa, after pressing it is left to harden for 24 to 48 hours in hermetic bags at room temperature and then removed from the bags and left in the ambient air for 7 to 28 additional days.
- the result is a hardened geomortar.
- Figure 1 Flowchart detailing the stages of the process for making the geopolymeric binder and geomortar.
- Figure 2 Effort curves vs. deformation for geomortars obtained from geopolymeric binders, showing average values of maximum resistance to uniaxial compression and elasticity modulus.
- Figure 3 Geopolymeric mortars made using mixtures of ignimbrite rock powders, demolition mortar and calcined clay.
- Figure 1 shows a preferred embodiment, detailing the stages of the process for making the geopolymeric binder and geomortar.
- Figure 2 shows that the results for the maximum average stresses obtained for demolition mortar, calcined clay and Ignimbrite rock residue geomortars were 58, 83 and 31 MPa, respectively, all of these values were higher than that of demolition mortar.
- Portland cement which presented an average maximum resistance of 17 MPa.
- the results for the average elasticity modulus obtained in demolition mortar, calcined clay and Ignimbrite rock residue geomortars were 38, 51 and 33 GPa, respectively, all these values were higher than that of mortar. of Portland cement, which presented an average modulus of elasticity of 20 MPa.
- the geopolymeric binder geomortar derived from calcined clay with a binder:sand mass ratio between 0.25 and 0.3, has average values of maximum resistance to uniaxial compression and modulus of elasticity above of Portland cement mortar in 388 and 155%, respectively.
- Figure 3 shows the results for the maximum average stresses obtained for the manufacture of geopolymeric mortars using powder mixtures of precursor binder material, it was carried out following the precursor binder:sand volumetric ratio of 20:80.
- Table 1 shows the proportions for each evaluated mixture.
- Table 1 The results for the average maximum stresses obtained from table 1 were 40, 26, 40, 25 and 19 MPa, respectively, all these values turned out to be higher than that of Portland cement mortar, which, as mentioned above, presented a maximum resistance average of 17

Abstract
La présente invention concerne un liant géopolymérique, un géomortier et des procédés d'obtention du liant géopolymérique et du géomortier à partir de résidus de l'industrie de la construction (résidus de roche ignimbrite, mortier de démolition, argile calcinée), le procédé est simple et facile à réaliser, sans ajout d'aucun autre liant connu (ciment Portland, chaux, plâtre, argile, pouzzolane ou cendre volante) et qui présente de bonnes propriétés mécaniques à la compression uniaxiale. L'incorporation d'un composant durcisseur unique (hydroxyde de sodium) est cohérent avec le dessein d'éviter de nuire à la formation d'une solution homogène et évite l'augmentation de la complexité du procédé de fabrication de géomortiers ou de liants.
