Hypothesis
Can the addition of perlite and cenospheres improve the thermal insulation of fly ash-based geopolymer composites without compromising their strength?
Conclusion
The study found that optimal dosages of perlite dust and cenospheres significantly improved the thermal insulation of geopolymer composites while maintaining adequate compressive strength.
Supporting Evidence
- The optimal dosage of additives was around 75 kg per cubic meter of the mixture.
- The average compressive strength values were at least 3.5 MPa.
- Thermal conductivity values ranged between 0.18 and 0.24 W/(m·K).
Takeaway
This study shows that adding certain materials to geopolymer mortar can make it better at keeping heat in, which is good for building insulation.
Methodology
The study used a two-factor experimental design to test different dosages of perlite powder and cenospheres in geopolymer mortar.
Limitations
Further analysis considering life cycle parameters, including carbon and water footprints, is necessary to validate the findings.
