ABSTRACT This study addresses the influence of key processing variables on the hydrothermal alkaline treatment of low‐temperature fired kaolin‐aggregates for the development of zeopolymers (zeolite–geopolymer composites). Parameters such as hydrothermal treatment temperature (90 and 150°C), reactor volume (250 and 500 mL), liquid‐to‐solid (L/S) ratio ...
