ANALYSIS OF ELASTICITY IN WOODS SUBMITTED TO THE STATIC BENDING TEST USING THE PARTICLE IMAGE VELOCIMETRY (PIV) TECHNIQUE
Provedor de dados: 70
Autores: Pereira,Rodrigo A.; Gomes,Francisco C.; Braga Júnior,Roberto A.; Rivera,Fernando P.
ABSTRACT The most important parameter in terms of material mechanical behavior knowledge is the modulus of elasticity, being traditionally obtained through destructive tests. The objective of this study is the verification of the potential use of the particle image velocimetry technique (PIV) as a tool to obtain the modulus of elasticity in sawed wood samples (Pinus oocarpa and Eucaliptus grandis) and wood panels (Plywood, LVL and OSB). The PIV technique has as characteristics the low cost of equipment, fast results, no need for contact with the object tested, accuracy and possibility of application in the field. The application of the PIV technique occurred during the static bending tests where the deformations were also measured with a dial indicator...

PHYSICAL, MECHANICAL AND THERMAL BEHAVIOR OF ADOBE STABILIZED WITH “SYNTHETIC TERMITE SALIVA”
Provedor de dados: 70
Autores: Gandia,Rômulo M.; Corrêa,Andrea A. R.; Gomes,Francisco C.; Marin,Diego B.; Santana,Lucas S.
ABSTRACT Adobe is an efficient construction material for several reasons, such as its thermal comfort, sustainability, and lower energy cost, as well as the simplicity of its production and execution. However, challenges such as water absorption, capillarity, and compressive strength should be investigated to improve its physical and mechanical properties. “Synthetic termite saliva” (STS) is an excellent stabilizer with high cohesive and hydrophobic power. Therefore, the objective of this work was to evaluate the effects of STS incorporation into adobe, analyzing its physical, mechanical and thermal properties. Five treatments were studied: 0 (control); 0.1; 0.2; 0.4 and 0.8% STS by mass. These adobe samples were evaluated according to bulk density, linear...

PHYSICAL, MECHANICAL AND THERMAL BEHAVIOUR OF ADOBE STABILIZED WITH THE SLUDGE OF WASTEWATER TREATMENT PLANTS
Provedor de dados: 70
Autores: Gandia,Rômulo M.; Gomes,Francisco C.; Corrêa,Andréa A. R.; Rodrigues,Maykmiller C.; Marin,Diego B.
ABSTRACT The need for treated water is essential for life. With the constant increase in population, the most common way to purify surface water is through conventional water treatment plants (WTPs). The high volume of residue (sludge) generated in this process is most often returned to the catchment site, negatively affecting the ecosystem. The sludge of WTPs is similar to soil because it is composed of inorganic solids. Adobe is a construction material made from water and soil without the burning process, so it is considered sustainable, recyclable, and energy-efficient and can be stabilized with various materials. Therefore, the objective of this work is to develop adobes using the sludge of WTPs and to analyse their physical, mechanical and thermal...
