In order to save natural resources, recycling necessarily becomes a top priority for all of us, to save exhaustible resources, produce green energy and preserve the environment.In this perspective, we are trying to valorize a waste of animal origin, largely neglected by the actors of materials, through an industrial transformation into a biological charge to make new sustainable bio-composite materials.Using a tensile test bench, we try to mechanically characterize this biomaterial of renewable resources that, unlike eco-composites, has been neglected by the material actors.Obtained from waste, with a high recycling potential and from renewable resources, the bio-charge to be analyzed will be injected, later in different polymer materials in order to support the evolution of their physicochemical properties: resistance to elongation, wear, heat, corrosion, etc.Consequently, we will be able to contribute to an eco-design of sustainable materials with safeguarding exhaustible resources and preserving our environment

Abstract Renewable resources are used to create useful, biologically sustainable materials. It has the potential to minimize waste while also challenging existing research and developments. Several researchers have concentrated their efforts on natural fiber composites. Natural fibers include plant, mineral, and animal fibers. In this project fish scales, a bio-waste, were used as a reinforcing agent in polyester/polystyrene for the fabrication of composite materials in the different weight fractions of 0, 6, 7, 9, and 11%, at a constant load of 1 N and temperature of 20 and 26°C. The hand layup technique was used to create the fabrication setup for composite materials. The creep behavior, modulus of elasticity, and stress were studied experimentally.

This paper aims to investigate the influence of utilization micro cement kiln dust as a sustainable materials additive in order to reduce the voids and micro cracks in the cementitious mortar materials which cause a drastic reduction in the load carrying capacity of the element. Its therefore very important to decrease the pores and enhance the mechanical strength of the cementitious composite materials. In this article, the properties of self-compacting mortar containing micro cement dust additive was experimentally assessed. Micro cement dust powder was added to the self-compacting mortar in (1, 2, 3, 4 and 5 %) percentage by weight of cement to be used as cementitious sustainable materials. The experimental results indicated that the modification and enhancement of the workability of fresh mixture and the mechanical strengths of self-compacting mortar were increased as micro cement dust additives increases. Also; the water absorption and total porosity were decreased with increases of micro cement dust powder.

The main methods (pressing and winding) of the processing of hybrid polymer composites to obtain items were examined. Advantages and disadvantages of the methods were noted. Good combinations of different-module fibers (carbon, glass, boron, organic) in hybrid polymer materials are described, which allow one to prepare materials with high compression strength on the one hand, and to increase fracture energy of samples and impact toughness on the other hand.

Abstract The control of the quality of mixture based on very short carbon fibers and epoxyde resins leads to suitable mixture for molding of complex geometries. A gain in fluidity is obtained if the suspensions are treated by ultrasounds and simultaneously stirred under vacuum. Addition in a very small ratio of microbubbles in the mixture allows to obtain a viscosity less than those of the matrix alone. For many polymer materials the gain of fluidity can be of 20 to 25% with size and concentration of the microspheres thoroughly chosen. A certain number of new resins is developped to elaborate composite materials with specific mechanical properties close to standard aluminium. Tensile test an ultimate stress are used to quantify the improvements of the mechanical properties. Fillers concentrations up to 30 % are obtained.

Composites are materials which synergically combine properties of each phase – matrix and filler. Polymer materials can be used as matrix while inorganic and organic particles can be used as fillers. Composite systems based on renewable resources can be designed as an interesting material for engineering. This paper describes on the tribological and other mechanical properties of biocomposites based on polymer resins and microparticles - seed cakes, which were obtained from seeds of the plant Jatropha Curcas L. during pressing. The particle size obtained was 573 µm.The results confirmed that the epoxy and polyurethane resins were capable of forming which corresponds to the interaction with the organic particles prepared from the seeds of Jatropha Curcas L. The presence of particles however, changed the mechanical properties of the resins. In the case of epoxy resins and polyurethane (Sika Force 7723), the hardness according to Shore D identically decreased with a maximum of 1.9. Abrasion resistance decreased due to the presence of particles of 0.0393 cm3 for Glue Epox Rapid, 0.0449 cm3 for Epoxy 1200/324 and 0.0567 cm3 for Sika Force 7723.

Polymer composite materials can be produced by reinforcing carbon black, carbon fiber, graphite, graphene, metals and metal oxides, nanotubes, and so on. These types of composite materials can be employed in applications demanding electrical conductivity besides high specific strength and stiffness properties of polymer materials. In the literature, there is a lack of knowledge on the examination of drilling of particle-reinforced composite materials. In this study, drilling of pure polypropylene and carbon black–reinforced polypropylene composite material was investigated at different drill point angles, cutting speeds, and feeds. The cutting temperature of drill point and surface roughness of holes were examined. The experimental studies were designed by L27 full-factorial design, and analysis of variance statistical method was performed. According to the results, cutting temperature increased and surface roughness decreased with the increase in the cutting speed and feed and decrease in the drill point angle.

Sustainable Building Materials

The construction industry is one of the industries accounting for a large proportion of Vietnam's overall GDP. It is also one of the least sustainable industries with extensive use of non-renewable resources. A study on the current situation of occupational awareness of sustainable building materials, identifying factors that prevent the diffusion of sustainable building materials is critical. The present study raised the theoretical basis of using sustainable building materials for the construction industry. Questionnaire data from 130 valid responses were used to carry out statistical analysis and make interpretation of results. The results indicate no significant difference between the two groups of respondents in awareness, belief, and readiness towards sustainable materials. The awareness and readiness levels are higher among construction practitioners who have experience. The present findings might suggest several courses of action to solve the problem of sustainable materials being overlooked. Our research suggests that it is essential for policymakers to encourage stakeholders to consider sustainability more seriously. The research findings have profound managerial implications that experienced practitioners might significantly impact the decision-making process in the realm of sustainable orientation. Future work should concentrate on integrating sustainable building materials into innovative and transformative practices in the construction industry.
