Biomaterials are materials that are used to manufacture devices that interact with biological systems. According to their chemical composition, they can be classified as biometals, biopolymers, bioceramics, biocomposites and semiconductors. Thus, in the present work, the application of bioceramics, enhanced with effective microorganisms, to...

The construction sector has an important role to play in reducing the threat of climate change. Thus, this work proposes, analyses, and compares two constructive strategies for the intervention/rehabilitation of a protected building located in Seville (Spain). The first solution intends to follow traditional techniques and standardized...

La experiencia docente que se presenta se enmarca dentro de la asignatura de Construcción 6, del Grado en Fundamentos de Arquitectura de la Universidad de Sevilla. Hasta el momento, en la parte teórica de la materia se seguía un procedimiento de clase magistral mediante la forma tradicional. Sin embargo, y con el objetivo de romper un poco con...

La experiencia presentada se enmarca dentro de las asignaturas del Módulo de Envolventes de la titulación. Debido al carácter profesional de los estudios, se pretende con esta actividad acercar al estudiante a la práctica profesional. Para ello, se puso en marcha una experiencia piloto en las sesiones referidas a cubiertas planas, empleando...

Purpose In the context of worldwide efforts to reduce plastic waste, the authors of this document patented a cement mortar floor slab interjoist prefab vault incorporating recycled plastic. This piece was designed to be used for the refurbishment of Spanish traditional timber jack arch floor slabs. Taking into account nowadays context, it is...

The utilization of superabsorbent polymers (SAPs) in cement-based materials has been found to be a promising means of mitigating the autogenous propagation of shrinkage and cracks. On the other hand, the undesired effects of SAPs' application on functional properties, including mechanical strength, microstructure formation, and the evolution of...

Large amounts of different types of waste are generated each day in the world. Most of them do not receive proper management at the end of its useful life. In that sense, and trying to apply eco-efficiency criteria, the construction sector has recently been working on the design of new building materials that incorporate some types of residues....

Nowadays, the growing demand of plastic is leading to an uncontrolled waste production that threats the Planet's health. Over 8 million tonnes of plastic debris go into the ocean annually because of poor end-life management. Single-use products represent one of the main sources of plastic pollution, due to its low recycling rate related to its...

Over 367 million metric tons of plastic were produced worldwide in 2020. Within the most consumed standard plastics, low-density polyethylene (LDPE) is the second resin most demanded in Europe. Far from reducing its consumption, this continues to grow despite environmental impact. Due to the low recycling rate of LDPE waste (~35%), coming...
