Item Study of Mechanical Behavior of Geopolymeric Mortars Reinforced with Ichu Fibers(Universidad Católica San Pablo, 2022) Rodríguez Guillén, Gerhard Paul; Cuzziramos Gutierréz, Fernando Alonso; Bringas Rodriguez, Veronica CeciliaReinforced geopolymeric mortars were manufactured by mixing mining tailings, fine sand, Ichu fibers (in variable percentages), sodium hydroxide and water. The microstructure of the obtained mortars consisted of a continuous geopolymer binder phase with sand particles and Ichu fibers dispersed within the binder phase. The real density and average porosity of the reinforced mortars was 2.74 g/cm3 and 34%, respectively. It was possible to verify the influence of the addition of Ichu fibers on the mechanical response in uniaxial compression of the studied mortars, due to the poor interface between the geopolymer and the fibers. The mechanical results revealed a systematic reduction of the maximum compressive strength when the volume of Ichu fibers in the mortar mixtures was increased. On the other hand, a higher degree of deformation was evidenced in mortar mixtures containing a greater amount of Ichu fibers, reaching deformation values of up to 5%. The maximum resistance values found were from 2.87 to 20.76 MPa for samples with 8 and 0 vol.% of Ichu fibers added, respectively.Item Architecture and sacred landscape in pre-hispanic peru: A comparative approach from a gis perspective(Springer Nature, 2021) Zeballos-Velarde, C.; Vizcarra, G.R.One of the most relevant characteristics of the “landscape-friendly societies” is their ability to recognize aesthetic attributes to portions of the territory that exceed their functional purpose. In ancient Peru, there were many ways of relating architecture (religious, civil and production) with a broader “borrowed landscape”.This article presents a comparative multi-temporal analysis of the landscape relationships with sacred elements from different pre-Hispanic cultures in Peru, using remote sensing tools and geographic information systems. This approach allows to distinguish and compare factors of visibility, insertion in geomorphology, trace and metaphor, in relation to distinctive elements of the landscape such as mountains, rivers, lakes and deserts. Five representative cases have been selected for territorial studies: Moche, Wari, Pisac, Ollantaytambo and Sacsayhuaman, analyzing factors of urban and site composition and their relationship with their landscapes. Also, for an architectural level, a cloud-point model of Sacsayhuaman has been used for the study of solar alignment. Finally, a correlation is proposed between the morphology of architectural developments in the Andean territory with the system of beliefs that came together to model each place, forming sacred landscapes.
