Toward low-carbon: The dual role of wood fly ash in enhancing fire resistance and CO₂ reduction in cementitious systems

The primary hypothesis is that replacing a portion of cement with WFA can improve the material’s thermal resistance while reducing overall carbon emissions associated with cement production. The dataset includes experimental results such as, spreading test, bulk density, residual compressive strength, after exposure to elevated temperatures,thermogravimetric analysis (TGA) and SEM.

These data were collected through standardized laboratory testing of concrete specimens containing different WFA replacement ratios. This data can be used by researchers and engineers to evaluate the thermal performance and environmental benefits of WFA-blended cementitious systems, and to optimize mix designs for sustainable construction applications.
