Affordable prefabricated modular houses using cement and polymer based materials and advanced design tools

By taking advantage of the appropriate use of cement and polymer based materials and advanced computational tools, a pre-fabricated affordable house was built in a modular system. Modular system refers to the complete structure that is built-up by assembling pre-fabricated sandwich panels composed of steel fibre reinforced self-compacting concrete (SFRSCC) outer layers that are connected by innovative glass fibre reinforced polymer (GFRP) connectors, resulting in a panel with adequate structural, acoustic, and thermal insulation properties. The modular house was prepared for a typical family of six members, but its living area can be easily increased by assembling other pre-fabricated elements. The speed of construction and the cost of the constructive elements make these houses competitive when compared to traditional solutions. In this paper the relevant research subjacent to this project (LEGOUSE) is briefly described, as well as the construction process of the built real scale prototype.

HLT Hilotec: self-building manual for sustainable housing

The future of the construction industry will require changes at many levels. One is the ability of companies to adapt to new challenges, converting needs to opportunities and simultaneously contributing to the solving of social and environmental problems. In the coming decades we will see a change in attitude in the industry, with a strong tendency to adopt natural and recycled materials, as well as bet on green technology and social innovation oriented to emerging countries. On the other hand, emerging countries have a high demand for housing construction on a large scale, but the current techniques in the developed countries for building requires a large amount of natural resources and skilled labor. This contextualization brings sustainability problems for the construction sector in emerging countries, often with scarce natural resources and with the construction sector underdeveloped. Through a cooperative action between the construction company Mota-Engil Engineering and the University of Minho in Portugal, a construction technology was developed based on the use of Compressed Earth Blocks as part of a social concept for innovative small houses, favoring the adoption of local and natural materials and with the main premise of being dedicated to self-construction. The HiLoTec project - Development of a Sustainable Self-Construction System for Developing Countries was based on this idea. One of the several results of this project is this construction manual. To Mota-Engil the project was a platform for incubation of knowledge about earth construction and to obtain a constructive solution validated technically and scientifically, suitable to be implemented in the markets where it operates. For the University of Minho the project was an opportunity to strengthen skills in research, laboratory and scientific development, through the development of engineering studies, architecture and sustainability, as well as supporting the doctoral scholarships and dissemination of scientific publications. May the knowledge of this project be of benefit, in the future, for the welfare of those who build a HiLoTec house.

Evaluation of the performance of recycled textile fibres in the mechanical behaviour of a gypsum and cork composite material

Given the need for using more sustainable constructive solutions, an innovative composite material based on a combination of distinct industrial by-products is proposed aiming to reduce waste and energy consumption in the production of construction materials. The raw materials are thermal activated flue-gas desulphurization (FGD) gypsum, which acts as a binder, granulated cork as the aggregate and recycled textile fibres from used tyres intended to reinforce the material. This paper presents the results of the design of the composite mortar mixes, the characterization of the key physical properties (density, porosity and ultrasonic pulse velocity) and the mechanical validation based on uniaxial compressive tests and fracture energy tests. In the experimental campaign, the influence of the percentage of the raw materials in terms of gypsum mass, on the mechanical properties of the composite material was assessed. It was observed that the percentage of granulated cork decreases the compressive strength of the composite material but contributes to the increase in the compressive fracture energy. Besides, the recycled textile fibres play an important role in the mode I fracture process and in the fracture energy of the composite material, resulting in a considerable increase in the mode I fracture energy.

Seismic behaviour of portuguese rammed earth buildings

Rammed earth is one of the oldest building materials in the world and is present in the Portugal with a particular focus in the South of the country. The mechanical properties and the structural behaviour of rammed earth constructions have been the subject of study of many researchers in the recent years. This study is part of a broader research on vernacular seismic culture in Portugal. Numerical analyses were carried out on a rammed earth masonry construction representative of the vernacular heritage of Alentejo region. Variations in the geometry, constructive characteristics and material properties were implemented and the main conclusions of the non-linear static and modal analysis are presented. Analysing the damage framework allowed interpreting the weaknesses of this type of constructions and consider the most appropriate reinforcement methodologies.

Search for New Phenomena in Dijet Angular Distributions in Proton-Proton Collisions at s√=8 TeV Measured with the ATLAS Detector

A search for new phenomena in LHC proton-proton collisions at a center-of-mass energy of s√=8 TeV was performed with the ATLAS detector using an integrated luminosity of 17.3 fb−1. The angular distributions are studied in events with at least two jets; the highest dijet mass observed is 5.5 TeV. All angular distributions are consistent with the predictions of the Standard Model. In a benchmark model of quark contact interactions, a compositeness scale below 8.1 TeV in a destructive interference scenario and 12.0 TeV in a constructive interference scenario is excluded at 95% CL; median expected limits are 8.9 TeV for the destructive interference scenario and 14.1 TeV for the constructive interference scenario.

Educação e ambiguidades da autonomização: para uma pedagogia crítica da promoção do indivíduo autónomo

O presente artigo, confrontando a educação com o desiderato da autonomização, pretende analisar as ambiguidades a que esse confronto dá hoje origem e estabelecer, mediante a explicitação de uma conceção contra-hegemónica de autonomização, as bases e as coordenadas de uma pedagogia crítica da promoção do indivíduo autónomo, que seja simultaneamente humanista, emancipadora e transformadora tanto da realidade do sujeito quanto da realidade do contexto. A estrutura narrativa, em consonância com esse amplo propósito, articula as seguintes dimensões: a educação e a normatividade da autonomização; as ambiguidades da autonomização: sentidos divergentes de fazer educação para a autonomia; e, por fim, o empowerment emancipatório e transformador: vetor da educação enquanto autonomização contra-hegemónica. A conclusão aponta as linhas diretoras da construção de uma pedagogia crítica do indivíduo autónomo, assumida nas vertentes de emancipação individual e transformação social.

Cultura, liderança e resultados escolares: uma abordagem a partir das representações dos alunos do ensino secundário

Grande parte dos estudos produzidos sobre a liderança escolar tem incidido na análise da relação entre os processos de liderança, a aprendizagem e o sucesso. Embora esta convergência de enfoque (liderança/sucesso) encubra abordagens teóricas, disciplinares e metodológicas muito diferenciadas, é evidente a presença de uma perspetiva unidirecional, mais focada nas políticas e nas práticas de liderança e menos na forma como estas são entendidas pelos alunos. Neste artigo, propomos um enfoque invertido, focado nas representações dos alunos sobre os processos de liderança. Do ponto de vista metodológico, recorremos aos dados recolhidos no âmbito de quatro estudos de caso realizados em escolas/agrupamentos com ensino secundário, resultantes da administração de um inquérito por questionário e da realização de focus group a alunos com resultados académicos de excelência e a alunos não incluídos neste nível de desempenho. Elegemos como referência analítica um estudo de caso de longa duração, a partir do qual colocamos em confronto os dados recolhidos nos outros três contextos estudados. Os resultados deste estudo apontam para a existência de relações e diferenças significativas entre a cultura organizacional da escola e os estilos de liderança, sendo destacada a importância do papel do Diretor na condução do ideário de excelência da escola.
