In the built environment, one of the main concerns during the design stage is the selection of adequate structural materials and elements. A rational and sensible design of both materials and elements results not only in economic benefits and computing time reduction, but also in minimizing the environmental impact. Nowadays, Artificial Neural...

Eco-efficiency and building optimization potential of prefabricated structures to be used in new buildings are studied, focusing on the analysis of a novel dry precast beam-column connection under different durability and re-using scenarios. The analyses include structural response (via numerical models), optimization potential (material take...

Biomass ashes can be used in cementitious materials as cement or sand substitution. Nevertheless, ashes resulted from the combustion of biomass in generation plants present drawbacks that can reduce their potential use if they are not previously treated. In this research, industrial sugarcane bagasse ash (SCBA) was mechanically activated by...

Terrestrial laser scanning is a widely used technology to digitise archaeological, architectural and cultural heritage. This allows for modelling the assets' real condition in comparison with traditional data acquisition methods. This paper, based on the case study of the basilica in the Baelo Claudia archaeological ensemble (Tarifa, Spain),...

This paper presents a numerical study on moisture transport in brick masonry walls with a special focus on the simulation of their hygric performance as well as the hydraulic phenomena at the brick-mortar interface. A diffusivity model based on Fick's law is used to describe the moisture transport accounting for both liquid and water vapor...

Masonry walls comprise an important part of the building envelope and, thus, are exposed to environmental effects such as temperature and moisture variations. However, structural assessment usually neglects the influence of these hygro-thermal loads and assumes ideal conditions. This paper presents a hygro-thermo-mechanical model and its...

This article presents an experimental study on the hygric performance of brick masonry with a special focus on the hydraulic characterization of the brick-mortar interface. The hygric behavior was studied at the level of the constituent materials as well as at the composite scale. An extruded fired-clay brick and two types of mortar –Portland...

The increasing urban development, led by concrete, requires a higher availability of materials and energy, and it will be responsible for a high waste generation. To face the exploitation of natural resources, the use of fossil fuels and the reduction of waste disposal, new environmental-friendly strategies emerge accomplishing the circular...

Uno de los principales detonantes del cambio climático son las emisiones de CO2. En el ámbito de la arquitectura y la construcción, uno de los materiales más perjudiciales en relación a su uso y su poder contaminante es el cemento (entre el 5 y 8% de las emisiones de CO2 en el mundo son generadas por éste). Por tanto, es fundamental buscar...

Microstructural and compositional analysis of historical mortars is an active research field, not only to guarantee the use of compatible repair measures, but also to guide the design of novel efficient materials. Despite the crucial role of Roman mortars in building history, there is a significant lack of knowledge of their pore system...

Phosphogypsum (PG) is a type of synthetic gypsum generated during the production of phosphoric acid. Each ton of phosphoric acid generates 5 tons of phosphogypsum. This industrial process has caused significant environmental problems worldwide. After an extensive literature review, it was possible to verify that both sedimentary and igneous PG...

Resumen: capacidades mecánicas suficientes para ser usados en refuerzos estructurales y que den resultados aceptables desde un punto de vista mecánico, económico y medioambiental. Tras realizar una exhaustiva revisión bibliográfica , se analizan las propiedades mecánicas, el comportamiento reológico, tiempo de fraguado, durabilidad e impacto...

El Proyecto Aura nace con el objetivo de desarrollar una línea de investigación enfocada en la vivienda social sostenible dentro de la Escuela Técnica Superior de Arquitectura de la Universidad de Sevilla en general y del grupo de investigación HUM-965_TRAnSHUMANCIAS en particular. La invitación recibida para participar en la competición de...

In this research, a comprehensive environmental-based approach is applied to evaluate the effectiveness of biomass ashes processing methods to produce cementitious materials. Efforts are put in research to obtain new low-carbon cementitious materials by incorporating waste, such as sugarcane bagasse ash (SCBA). Processing methods are commonly...
