Overview

Randomized trial demonstrates improved strength and environmental benefits in low-carbon concrete with silica and calcium admixtures, indicating potential for sustainable construction.

Key Points

  • This research aims to explore how silica-rich rice husk ash and calcium-rich seashell powder affect concrete properties and carbon emissions.
  • Incorporated RHA and SSP at 0%–25% of cement weight
  • Evaluated fresh and hardened properties via slump, compressive, and split tensile strength tests
  • Analyzed microstructural properties using scanning electron microscopy and energy-dispersive X-ray spectroscopy.
  • At 25% replacement, compressive strength increased significantly; specific values not reported.
  • Initial negative impact on mechanical performance observed at 5%–10% replacement, followed by improved strength at higher ratios.
  • Notable reduction in carbon emissions was recorded, demonstrating enhanced environmental performance.
