Curing of Concrete01:20

Curing of Concrete

149
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...

Area of Science:

  • Materials Science
  • Environmental Engineering
  • Virology

Background:

  • The COVID-19 pandemic underscores the critical need for effective pathogen removal strategies.
  • Basic sanitation and addressing social inequalities are vital for preventing disease outbreaks.
  • Efficient techniques and materials are required to remove emerging pathogens like SARS-CoV-2 from water sources.

Purpose of the Study:

  • To develop a cost-effective polyurethane (PU) biofoam incorporated with dregs waste for SARS-CoV-2 removal.
  • To evaluate the efficacy of the developed biofoam in eliminating SARS-CoV-2 from aqueous suspensions.
  • To compare the performance of the PU biofoam with dregs against conventional adsorbents.

Main Methods:

  • A polyurethane biofoam was synthesized using the free expansion method with 5wt% dregs waste.
  • Inactivated SARS-CoV-2 viral suspensions were incubated with the biofoam, isolated dregs, and control materials for 24 hours.
  • Viral RNA was extracted, and viral load was quantified using quantitative reverse transcription (RT-qPCR).

Main Results:

  • The polyurethane/dregs biofoam achieved a SARS-CoV-2 removal percentage of 91.55%.
  • Isolated dregs waste showed 99.03% removal, while commercial activated carbon reached 99.64%.
  • Neat PU foam demonstrated 99.96% removal, with no statistically significant difference observed among the high-performing materials.

Conclusions:

  • The developed polyurethane biofoam with dregs waste is a promising low-cost material for SARS-CoV-2 removal.
  • This biofoam offers an effective alternative to conventional adsorbents for water purification.
  • The study highlights the potential of industrial waste valorization in environmental remediation and public health.
