Over the past few decades, polymers have been extensively employed in various sectors
attributed to their exceptional properties. The presence of vast quantities of non-degradable …

This review provides a comprehensive study of the fundamentals of the alkaline and acid
activation of volcanic ashes (VA), for mainstreaming their use as a conventional feedstock …

This study investigated the impact of calcium carbonate nanoparticles (nano-CaCO 3) on the
mechanical properties of geopolymer composites. To that end, varying contents of nano …

Fly ash (FA) is a common industrial by-product, which is usually used as raw materials of
alkali-activated geopolymer or cement additive. However, there are few studies on …

Morocco has significant phosphate reserves, but the extraction process generates a lot of
waste rock. To tackle this problem, this study aims to make use of clay, a by-product of …

Coal ash-based geopolymers with mine tailings addition activated with phosphate acid were
synthesized for the first time at room temperature. In addition, three types of aluminosilicate …

This study is the first attempt to investigate the possibility of recycling carbonated lime
residue (CR)(a by-product from the sugar beet-making industry) as a foaming agent. For this …

The existing binders are difficult to be compatible with the acidic environment of acidic heavy
metal contaminated soil, it is hard to repair acidic heavy metal contaminated soil. In this …

The present work aims at producing volcanic scoria (Zg) based geopolymer containing high
volume of waste fired clay brick (WB). The objective was producing Zg-based geopolymer …

Phosphoric acid (PA)-based geopolymer is usually prepared with PA as activator. However,
the PA-based geopolymer using fly ash as raw material has not received much attention …
