“…The bonding between aggregates (granitic rock and macaúba endocarp) and cement-based matrix was evaluated via an adapted pull-out test [ 1 ], whose setup is shown in Figure 6 . With an embedment length of 10 mm, the aggregates were fixed on the machine grips by a 6.35 mm diameter round SAE 1010 steel bar epoxy (Sikadur-32, by Sika, Baar, Switzerland) glued on the top of each aggregate.…”

“…The development of non-conventional materials has been allowing one to design an array of novel structural elements that can be subjected to different environmental and loading conditions. For instance, bio-based aggregates, such as coffee husk [ 1 ], bamboo, rice and wood particles [ 2 , 3 ], allow the production of lightweight bio-concretes [ 3 ]. Other approaches can be made to produce eco-friendly materials, such as recycled aggregates [ 4 ] and artificial geopolymer aggregates [ 5 ].…”

This paper investigates the bond behavior between a bio-aggregate and a cement-based matrix. The experimental evaluation comprised physical, chemical, image, and mechanical characterization of the bio-aggregate. The image analyses about the bio-aggregate’s outer structure provided first insights to understand the particularities of this newly proposed bio-aggregate for use in cementitious materials. A mineral aggregate (granitic rock), largely used as coarse aggregate in the Brazilian civil construction industry, was used as reference. The bond behavior of both aggregates was evaluated via pull-out tests. The results indicated that both aggregates presented a similar linear elastic branch up to each respective peak loads. The peak load magnitude of the mineral aggregate indicated a better chemical adhesion when compared to the bio-aggregate’s. The post-peak behavior, however, indicated a smoother softening branch for the bio-aggregate, corroborated by the microscopy image analyses. Although further investigation is required, the macaúba crushed endocarp was found to be a thriving bio-material to be used as bio-aggregate.

“…In the present work, we determine the interfacial behaviour of various thermoplastics drops bonded to single flax fibres through the simulation of the microdroplet test using finite element method. This method has been considered to study the interfacial behaviour in varieties of materials such as carbon, glass as well as natural materials [23][24][25][26]. Flax fibres are combined with a selection of thermoplastic polymers matrices with contrasting mechanical properties and behaviour.…”

“…However, there are also negative aspects of wood fibers. The hydrophile character makes it more sensitive to environmental humidity (Ferreira et al, 2021). The -OH groups in the structure of wood fibers can easily bond with water molecules, which results in dimension instability (Ayrilmis et al, 2011).…”

Aim of study: This study aimed to improve some physical, mechanical properties, and fire resistance of wood-plastic composites (WPCs) with short glass fiber reinforcement (SGFR). Materials and Methods: The WPCs were reinforced with different ratios of short glass fiber (SGF). The effect of reinforcement on the water absorption (WA), thickness swelling (TS) as physical properties, flexural strength, modulus of elasticity, and tensile strength as mechanical properties were determined. The fire resistance performance was also evaluated by the limit oxygen index (LOI) test. Main results: The reinforcement improved the physical properties. The WA and TS values decreased with increasing glass fiber content. Flexural strength increased up to 28%, while 24% for tensile strength. There was a substantial enhancement in the modulus of elasticity (up to 122%). The glass fiber reinforcement also improved the fire performance of WPCs. Highlights: The higher properties could be obtained by synthetic fiber reinforcement for WPCs.
