CO2 sequestration and plastic waste utilization in geopolymer concrete: mechanical performance and sustainability assessment

ABSTRACT The environment impact of ordinary Portland cement and increasing plastic waste generation have advanced the search for sustainable construction materials. This study investigates the use of plastic char, generated from waste-plastic pyrolysis, as a 10% replacement for flyash in geopolymer concrete. A control...

Machine learning-driven prediction of compressive strength in sustainable geopolymer concrete using artificial neural network and random forest models

ABSTRACT Geopolymer concrete is a sustainable substitute for ordinary Portland cement which minimizes carbon dioxide emissions and effectively utilizes the waste from industries. Proper predictive estimating compressive strength can assist in the mix deign optimization, structural reliability. The article presents a ma...
