Caracterización y evaluación de las puzolanas del cantón Gonzanamá y Paltas

Abstract

This work concerns in the characterization and evaluation of pozzolanic material found in Gonzanamá and Paltas cantons, obtaining as a result the localization of 5 potential zones for Paltas canton being these: “La Ventolera”, “La Chamana”, “Las Cochas”,”Barrial Blanco” and Macandamine, while for Gonzanamá canton 3 potential zones were identified: “Jirunuma”, ”Jurupe” and “Purunuma”. With the development of physical, chemical (X ray fluorescence and diffraction) and mineralogical (thin section) tests it was possible to characterize the pozzolanic material in order to evaluate its application in concrete as its basic component; For this purpose, 288 cylindrical specimens were prepared in different dosages, obtaining as results with a 20% of substitution a maximum resistance of 21.08 MPa at 56 days of curing. This work contributes because it evaluates the use of new materials that could have their application in the industry providing an economic option for the manufacture of affordable housing with materials from the zone. With this background, a prototype of an assembly concrete block was developed in order to show that it is possible to use this pozzolanic materials in construction.
