The internal structures and the hygroscopicity of bio-based boards consisting of giant reed (Arundo donax L.) and hazelnut shells as bio-aggregates, and a sodium silicate solution as the adhesive, were investigated. The ...

The introduction of stored product insect pests to new areas is facilitated by food trade among countries, and effective detection and monitoring programs are crucial for food security. The khapra beetle, Trogoderma granarium ...

This study evaluated the durability of three innovative multilayer insulation systems incorporating thermal mortars with EPS aggregates and silica aerogel granules after hygrothermal accelerated aging and one year of natural ...

The European Union has been progressively introducing sustainable environmental policies which aim to improve the energy performance of new and existing buildings towards a climate-neutral building stock by 2050. As a ...

Insulation materials are fundamental for decreasing energy losses and guaranteeing thermal and acoustic comfort in buildings, which may significantly contribute to decreasing the energy consumption related with poor thermal ...

Subterranean termites, despite their essential role as decomposers on natural ecosystems, are voracious pests of wood in service, and may cause damage to wood in buildings and economic losses associated with treatments ...

External Thermal Insulation Composite Systems (ETICS) are frequently used to enhance the energy efficiency of the built environment. However, stains of presumable biological nature are often detected shortly after application, ...

Traditional carpentry joints can be found worldwide in many timber truss structures connecting rafter and tie beam. One failure mode of this connection result from shear in the tie beam beyond the notch either due to bad ...

Os ensaios de ligações aparafusadas realizados no LNEC no âmbito do projeto de investigação TimQuake abrangeram várias combinações de espécie (Pinus sylvestris e Picea abies) e teor de água da madeira, geometria da ligação ...

A tensão de cedência à tração dos aços dos varões para betão armado (fy), ou a tensão limite convencional de proporcionalidade a 0,2% (f0,2) no caso de esses aços não apresentarem cedência, constitui uma das principais ...
