Overview

Randomized trial investigates compressive strength in alkali-activated mortars with mussel shell waste, indicating sustainable construction options.

Key Points

  • The aim is to explore the effect of mussel shells as a partial replacement for slag in alkali-activated mortars.
  • Alkali-activated mortars produced with 0%, 5%, 10%, 15%, and 20% mussel shell by mass of ground granulated blast furnace slag.
  • Utilized sodium hydroxide and sodium silicate as alkaline activators.
  • Conducted tests on workability, strength, water absorption, porosity, capillarity, ultrasonic pulse velocity, and freeze-thaw resistance.
  • M0 series achieved the highest compressive strength at 54.06 MPa.
  • 5% and 10% mussel shell series showed strong compressive strength of 30 MPa after freeze-thaw cycling.
  • 10% mussel shell provided optimal balance in mechanical performance, freeze-thaw resistance, and microstructural stability.
