The effect of corchorus olitorius derived binder on the effective thermal conductivity of a
kaolinite-based refractory was investigated. Strong dependence of (effective) thermal
conductivity of fired samples on the binder concentration, temperature and porosity was
noted. Comparison of experimental data with Effective Medium Approximation (EMA) and
Geometric Mean Model (GMM) theories showed that predictions from EMA agreed better
with the experimental data than those from GMM. This was attributed to the EMA model
being more rigorous and contained more microstructural information than the simpler
GMM.
