Key Points

The aim is to evaluate the mechanical properties of pumice-based alkali activated materials using sodium hydroxide.
Utilized pumice powder as an active filler in AAM.
Evaluated the effect of sodium hydroxide molarity and curing time at 80°C on alkali activation.
Assessed activated AAM using FT-IR, XRD, and SEM-EDS methods.
The hardened AAM indicated strength potential comparable to Ordinary Portland Cement (OPC).
High molarity sodium hydroxide solutions suggested a risk of strength reduction due to gel aggregation.

Implication

This research evaluates the mechanical performance of pumice-based alkali activated materials, suggesting potential for reduced CO2 emissions.
