1. Mesh reinforcement in masonry mortar coatings: a systematic literature review
Abstract Mortar coatings have a major influence on a building’s aesthetics, valorization, and habitability, with significant effects on the mechanical behavior of masonry walls. Multiple types of meshes can be embedded in plaster to enhance both masonry and coating’s mechanical behavior, restrain crack formation, enhance the bonding between layers, and i

2. The Covid-19 pandemic seen from the frontline
ABSTRACT COVID-19 disease caused by infection with the SARS-CoV-2 virus produces respiratory symptoms, predominantly of the upper airways, which can progress to pneumonia after 7 days with persistent fever, cough and dyspnea, and even develop a syndrome of acute respiratory distress (ARDS), multi-organ failure and death. Since COVID-19 disease was declared b

3. CONSTRUCTION AND TESTING OF GLUED LAMINATED TIMBER FRAMES FOR USE IN LAYING POULTRY HOUSES
ABSTRACT This study aimed to present a solution in glued laminated timber to replace frame structures built in reinforced concrete and metallic structure, which are common in agricultural buildings in western Paraná such as those destined to laying poultry house building by agricultural cooperatives. Structural behavior of frames build from Araucaria angust

4. Geomechanical characterization of carbonates of the Sete Lagoas Formation (Bambuí Group)
Abstract The geomechanical properties of rock masses must be identified to assess their quality and employability; however, the methodologies may differ depending on the lithotype and analytical purposes. The present study aimed to estimate the not-well-known physical-mechanical properties of three types of carbonate rocks (calcarenite, calcilutite, and marb

5. Post-elastic Deformation Characteristics of Hybrid Fibre Reinforced Concrete Composites
Abstract The present study was focused on evaluating the strength and failure properties of hybrid micro-fibre concretes containing micro brass and steel fibre additions. Experimental tests were conducted on different hybrid fibre concretes containing aligned fibres in the direction of beam axis and the relative mechanical performance was compared to randoml

7. Mechanical behavior of PVD coatings deposited on ADI
ABSTRACT In this work, the mechanical behavior of the coated ADI system is studied. For this purpose, single layer Ti and bilayer Ti/TiN and TiAl/TiAlN coatings, with different thicknesses, were deposited by the PVD technique of cathodic arc deposition on high strength ADI substrates using industrial and experimental devices. The characterization of the coat

8. Bond strength evaluation between textiles reinforced mortar with carbon nanotubes and concrete substrate
Abstract The influence of using carbon nanotubes to improve bond strength between textiles reinforced mortar and concrete was investigated. Forty-two specimens were tested using double-shear test to evaluate the effect of various parameters such as CNTs addition, type of textile material, bond length and width, and number of TRM layers on the bond behavior.
