In the construction sector, concrete is indispensable. Non-structural uses account for a significant portion of concrete production. Foamed concrete (FC) is incredibly porous, and as the number of voids increases, the material's thermal characteristics decrease. Since these uses need a substantial amount of concrete, researching them might yield useful information for optimizing concrete's material efficiency and making better use of its waste products. FC is excellent in compression but poor in tension because it creates multiple microcracks. FC cannot withstand the tensile stress induced by the applied forces without additional reinforcement elements. Hence, this research investigates the mechanical properties of polypropylene (PP) fibers based foam concrete. The utilization of effective materials such as cement, flyash, silica fume and PP fibre were used in this investigation. In this study, a novel invention is proposed for designing and strength prediction of foam concrete and find out the strength properties such as compressive strength, split tensile strength and flexural strength of fibre reinforced foam concrete were determined and the experimental and predictive value of compressive strength were also determined with the help of python. The results provide a clear idea of the efficient use of fly ash and silica fume for the manufacture of light weight based products that promote profitability, sustainability and entrepreneurship for youth in developing countries such as India, and it is important by conserving natural resources through savings in the consumption of cement and aggregates.

Glass wastes are generated by various sectors is creating an environmental issue in our country. The reuse and recycling of Glass Waste Particles (GWP) is a way to reduce the environmental issues, cost of waste management and create sustainable environment. Construction industry is consumed major natural resources by the way of utilizing raw materials particularly making a concrete. The main aim of this experimental investigation is to obtain mechanical properties on concrete by replacing fine aggregate with GWP. In this study, fine aggregate was replaced with GWP from 0% to 40% in the interval of 10%. Based on the test results on concrete by replacement of fine aggregate in its weight of GWP were discussed in terms of compressive, split tensile and flexural strengths. Replacement level of GWP more than 30% produces lower strength. The replacement level of GWP between 20% and 30% in conventional mix may suit at construction industry. However, durability studies are required to study the long-term effect on concrete by replacing fine aggregate with GWP.

Emerging trends in extrusion-based additive manufacturing (AM) focus on improving the mechanical performance of pristine polymers with high strength reinforcing materials. Prominent reviews have indicated a heavy dependence on PLA polymer for fused deposition Modeling (FDM) based studies. To promote biodegradability, the effect of natural fibres as reinforcement has been widely researched in the literature. However, it is noted that discontinuous natural fibre reinforcement yields negative or negligible improvement in the strength and modulus of FDM-based biocomposites. Hence, an attempt to hybridise FDM with a conventional composite manufacturing method was made in this study by cladding natural fibre reinforcement over FDM-based polymer. Tensile and flexural test coupons were additively manufactured by FDM and reinforced with a skin of bi-directional woven basalt fibre through compression moulding. A 90% improvement in tensile strength and a similar significant increase in flexural strength was observed. Further, an average increment of 46.38% and 237.24% in tensile and flexural modulus, respectively, was achieved through this manufacturing technique. In conclusion, a drastic improvement in mechanical performance can be obtained through the hybridisation of manufacturing methods and needs further investigation towards the compatibility of adhesive materials with FDM polymers.

The global scientific community for the last three decades focuses mainly on polymer-based nanocomposites due to their ease of fabrication, flexibility, and above all easiness to handle them. Among the polymer materials, polyethylene got the attraction because of its readiness to be combined with most of the filler materials available in natural form as well as newly synthesized ones. The present study focuses on the synthesis of nanocomposites of Low-density polyethylene (LDPE) with graphene oxide nanoparticles as the filler. The graphene oxide nanoparticles are synthesized using a modified Hummers method. The composites are prepared by varying the amount of graphene oxide nanoparticles in the LDPE matrix using the melt extrusion method. The nanocomposites prepared were found to have good mechanical properties compared to the virgin LDPE material. The Dynamic Mechanic Analysis (DMA) confirmed that the quantity of the graphene oxide nanoparticles has a major role in the viscoelastic behaviour of the composites.

Titanium and its alloys have a wide range of applications in various industries, including medicine. However, the low strength and high friction coefficient hinder their development in contact friction due to fretting fatigue. Among many factors, structure refinement, temperature and amplitude are the most responsible for fretting wear of structural materials. The purpose of the article is to investigate the effect of displacement amplitude, size of grain and test temperature on the fretting wear of the pure titanium in coarse-grained and ultrafine-grained states. It is shown that an increase in the test temperature for both structural states leads to a multiple increase in wear. Structural refinement of titanium to hundreds of nanometers helps to reduce wear at room and elevated temperatures.

Recycling of aluminium alloys is gaining significant attention due to its economic and environmental benefits. However, close loop recycled aluminium alloys can be adversely affected by impurities and alloying elements present in the recycled feedstock. In this study, the influence of three composites, namely alumina (Al2O3), ferric oxide (Fe2O3), and manganese (Mn), on the properties of recycled aluminium taldon scraps was investigated to enhance the tensile behaviour of the alloys. The effects of these composites on the mechanical properties, microstructure, and corrosion behaviour of the recycled aluminium alloys were evaluated through experimental characterization techniques. The results showed that the addition of these composites had a significant influence on the properties of recycled aluminium alloys, providing insights into the potential for improving the performance of recycled aluminium alloys through composite additions. The addition of Al2O3 enhanced the tensile strength by 44.18 % and the variation can be attributed to the strengthening of the dendritic zones by the formation of α-Al.

Commercial and industrial use of 3D printing has swiftly taken off as a versatile and effective method of manufacturing on both a small and large scale. Despite being adaptable, the procedure currently works with a restricted number of materials, mostly thermoplastic polymers. 3D printing fused deposition modeling (FDM) provides opportunities to produce complex components relatively quickly in small batch with a high degree of flexibility for both manufacturer and researcher. Process parameters in FDM like infill pattern, infill density, printing speed, raster angle influences the mechanical properties of a printed parts. In this research study, a novel approach on the internal structure of 3D printed parts say combined infill pattern (Triangles & Octet) on a single part has been introduced and mechanical properties like tensile test, flexural strength, compression strength and hardness were measured. Specimens were printed in Acrylonitrile butadiene styrene (ABS) as per ASTM standards by FDM technology with different infill densities of 60%, 80% and 100% by XY build orientation. SEM analysis was made to analyze the morphological and inter bonding of different infill patterns. The results show that mechanical performance was inflated by an increase in infill density.

Asbestos-based brake shoes are being faded out due to worries that they may cause cancer; as a result, research for suitable replacements is an essential area of focus. Research on agricultural by - products such as flax fibres, rockwool, aramid fibres, banana fibres, and nut shells from palm trees have been used to develop a number of potential replacements for asbestos. Palm wastes, which are picked for the study since there was a paucity of previous research on the topic, are obtained from agricultural waste fibres. As part of this investigation, a composite material was created, and a number of tests were carried out in order to investigate the wear and durability of a set of unique composites. The novel composites contained 20% epoxy resins, 10 % carbon, 15% CaCO3, 30–45% PKS, and 10–25%Al2O3 respectively. The results obtained showed that the finer the sieve size the better the properties.
