Recycled Surgical Mask Waste as a Resource Material in Sustainable Geopolymer Bricks

Recycling, Journal Year: 2023, Volume and Issue: 8(6), P. 93 - 93

Published: Nov. 19, 2023

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.

Assessing performance of alkali-activated bricks incorporated with processed surgical masks

Journal of Materials Research and Technology, Journal Year: 2023, Volume and Issue: 25, P. 6432 - 6445

Published: July 1, 2023

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.
