Abstract A tremendous amount of the nonbiodegradable microplastic waste has been generated after outbreak COVID‐19 by widespread use single‐use personal protective equipment, especially disposable medical masks (DMMs). This caused harm to health and safety human beings various organisms. Finding a way properly deal with these wastes become an urgent problem. In this paper, innovative was explored DMMs in geopolymer (GP). The physical properties, mechanical strength, resistance high temperatures (200–800°C) composites were investigated. findings study revealed that had negligible influence on temperatures, but showed positive enhancing compressive flexural strengths GPs at ambient temperature. optimum content 0.4 wt%, which GP enhanced 5.8% 22.68% compared pure GP, respectively. same polypropylene (PP) fiber increased 7.49% 9.76%, thus confirmed can be sustainably utilized green building materials, playing role as PP fibers toughening contributing effective management plastics.

ABSTRACT Incorporation of disposable medical masks (DMMs) can improve the basic mechanical performance and crack resistance geopolymer composite (GPC). To interfacial bonding, DMMs were chemically modified using four silane coupling agents: KH550 (aminopropyl‐triethoxysilane), KH560 (glycidyletheroxypropyl‐trimethoxysilane), KH570 (3‐methacryloxypropyltrimethoxysilane), KH792 (N‐(β‐aminoethyl)‐γ‐aminopropyltrimethoxysilane). Macroscopic tests performed to assess compressive flexural strengths GPC. Additionally, microstructural carried out Fourier transform infrared spectroscopy (FTIR), Stereomicroscope, Scanning electron microscope (SEM) gain deeper insights into modification effects. Results showed that all agents enhanced hydrophilicity significantly improved overall composites. Among them, demonstrated most effective modification. The 28‐day GPC incorporating KH560‐treated reached 49.91 MPa 6.55 MPa, respectively, which 8.12% 30.22% higher than those containing untreated DMMs. FTIR SEM analyses revealed enhancement mechanism involved physicochemical interactions between matrix, led stronger bonding performance.

With the advent of COVID-19 pandemic, global consumption single-use surgical masks has risen immensely, and it is expected to grow in coming years. Simultaneously, disposal environment caused plastic pollution, therefore, exigent find innovative ways handle this problem. In study, were processed a laboratory using mechanical grinding method obtain recycled (RSM). The RSM was added doses 0%, 1%, 2%, 3%, 4% by volume geopolymer bricks, which synthesized with ground granulated blast furnace slag (GGBS), rice husk ash (RHA), sand, sodium silicate (Na2SiO3) at ambient conditions for duration 28 days. developed bricks tested compressive strength, flexural density, water absorption, efflorescence, drying shrinkage. results study reveal that strength improved inclusion bricks. highest values 5.97 MPa 1.62 RSM, respectively. Further, reduction self-weight noticed an increase RSM. There no pronounced effect on absorption efflorescence properties. However, played role reducing shrinkage sustainability analysis divulges catalytic improving material performance, thereby proving be potential candidate low-carbon construction industry.

Since last few years the world is facing tremendous surge in use of surgical masks due to COVID19 pandemic. The uncontrolled disposal environment will pose serious threat living organisms plastic pollution. On other hand, construction industry hugely dependent on natural resources, leading increase carbon footprint. Therefore, it necessary investigate novel materials with sustainability perspective. In present study, alkali-activated bricks were synthesized rice husk ash (RHA), ground granulated blast furnace slag (GGBFS), sand, and sodium silicate (SS). To this, processed (PSM) added varying doses 0%, 1%, 2%, 3%, 4% by volume mix. results revealed that addition PSM significantly improved strength properties a maximum compressive 6.85 MPa at inclusion PSM. At same time, has reduced density minimum value 1.54 g/cm3 incorporation slightly increased water absorption porosity bricks, 4.76% 7.75% for PSM, when compared 0% respectively. accelerated ageing test showed after three cycles wetting drying exhibited loss range 55.2% 58.6%. microstructure bridging effect fibrous mask particles improving load transfer polymer matrix, thereby reducing brittle tensile failure bricks. pushover analysis benefit performance infill walls improvement brick reduction its self-weight, therefore, can be considered as potential material buildings seismically vulnerable areas.
