OVIEDO-SANCHEZ, Katherine  y  MEJIA-DE-GUTIERREZ, Ruby. Geopolymeric Mortar for Potential Use as a Concrete Coating. Rev.EIA.Esc.Ing.Antioq [online]. 2019, vol.16, n.31, pp.159-170. ISSN 1794-1237.  https://doi.org/10.24050/reia.v16i31.1243.

In the present study, two geopolimeric mortars based on Metakaolin and brick residue were synthesized; these were modified with organic and inorganic additions to be used as potential coatings on concrete. Properties in a fresh state (fluidity, setting time) and in a hardened state (compressive and traction strength, absorption, porosity and thermal conductivity) were evaluated. The results show the feasibility of producing Class R1 and R2 mortars in accordance with the EN 1504-3 Standard in terms of mechanical properties. The geopolymeric systems produced have a lower thermal conductivity compared to mortars based on OPC, which suggests its use as insulating coatings.
