Development of Sustainable Paver Block to Suit Very Heavy Traffic Conditions Using Cassava Peel Ash

Engineering Reports, Volume 8, Issue 5, May 2026.
Sustainable paver blocks were developed using cassava peel ash and silane‐treated glass fibers. The optimized mix achieved superior strength, durability, and impact resistance, meeting IS 15658:2006 standards for heavy traffic. This eco‐friendly approach highlights an effective use of agro‐waste and fiber reinforcement for sustainable infrastructure ...

Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

ChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...
