Evaluation of bamboo particleboards produced with urea-formaldheyde resin
(2014)
The bamboo waste can be an alternative material to sustain the crescent demand for particleboards, also bringing ecological benefits as reduction of the pressure for raw materials and landfill space demands. In this context, ...
Durabilidad de madera termotratada de Gmelina arborea (Roxb. ex Sm) y Tectona grandis (L.f.) en Costa Rica
(Instituto Tecnológico de Costa Rica, 2015)
Wood is a biological material composed of cellulose, hemicellulose and lignin. It has been used through the years in outdoors and indoors. However, it is susceptible to degradation, for that reason some techniques have ...
Estudo da rigidez, da deformação permanente e da fadiga de misturas asfálticas com ligantes convencionais e modificados
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-11-22)
In Brazil, there are two most recurrent defects found on highways: permanent deformation and cracking due to fatigue. Among the most varied causes, the formation and propagation of cracks in the asphalt coating occurs as ...
