A potential way of improving the material efficiency and cost effectiveness of the Direct Metal Laser Deposition (DMLD) process is to take powder that is not utilised in each deposition attempt and re-use it in subsequent attempts (powder recycling). Currently, this is not widely implemented for fear of a detrimental effect on part quality. This study examines how powder recycling, using simple...

Low dielectric loss and low-cost recycled borosilicate (BRS) glass-reinforced polytetrafluoroethylene (PTFE) composites were fabricated for microwave substrate applications. The prepared through a dry powder processing technique by dispersing different micron sizes (25 µm, 45 63 90 106 µm) of the BRS filler in PTFE matrix. effect on composites’ thermal, mechanical, properties was studied. chara...

These days, the world is facing a global environmental and sustainability problem due to increasing generation of large amounts waste through construction demolition work, which causes serious for environment. Therefore, this research was conducted get rid disposal problems, including old glass concrete, were used as recycled fine aggregates. Seven different mixtures prepared. The first mixture...

A Calcium silicate hydrate (CSH) powder containing above 60 wt% xonotlite (remaining being tobermorite, scawtite and calcite) were produced from lime ordinary recycled soda-lime glass via simple hydrothermal synthesis route. The thermogravimetric analysis demonstrated only ~20%weight loss up to 800 °C (at about the transformation temperature of CSHs wollastonite), reaching a plateau in 800–1200...

Abstract Annually, there is an enormous amount of glass waste created worldwide, yet only a small portion that material recycled. Recovering (WG) in concrete demonstrates excellent progress lowering the glass. Researchers have found adding to improves its qualities; WG can be utilized as powder, fine well coarse aggregate. However, question arises how this powder added improves, or at least mai...

Additive manufacturing (AM) techniques can produce complex, high-value metal parts, with potential applications as critical parts, such as those found in aerospace components. The production of AM parts with consistent and predictable properties requires input materials (e.g., metal powders) with known and repeatable characteristics, which in turn requires standardized measurement methods for p...

In this study, different glasses were investigated to improve reusable investments. Borosilicate glass (BSG) powder and soda-lime glass (SLG) powder were prepared by milling broken beakers and microscope slides, respectively, and used in experimental investments (I-BSG, I-SLG) by blending glass powder (10 wt%) with cristobalite (90 wt%). Some properties and casting fits were evaluated with comm...

Cement plays a vital role in concrete production; as binding agent, it holds together the aggregates concrete. Manufacturing of cement and glass causes depletion natural resources endangerment environment. Both industries are energy consumers responsible for hazardous greenhouse gases, particularly nitrogen oxides. The contribution industry toward emissions is 5% globally, estimated that one to...

Abstract This study focuses on formulating the most sustainable concrete by incorporating recycled aggregates and other products retrieved from construction demolition (C&D) activities. Both coarse (RCA) fine (RFA) are firstly used to fully replace natural in mix design. Later, cement rich ultrafine particles, glass powder mineral fibres recovered wastes (CDW) further incorporated at a smaller ...
