Silico-aluminophosphate and Alkali-aluminosilicate Geopolymers: A comparative review
TL;DR: In this paper, a state-of-the-art review on silico-aluminophosphate (SAP) geopolymers in terms of definition, chemistries involved during geopolymerization, mechanical and durability performance, environmental impacts, and their potentials in applications is presented.
Journal ArticleDOI
Synthesis of zeolite P1 from fly ash under solvent-free conditions for ammonium removal from water
TL;DR: In this article, the formation of zeolite P1 is investigated as a function of crystallization reaction time, and the efficiencies of the resultant zeolites for ammonium adsorption are evaluated on factors including solution pH, NH4+ ions concentration, temperature and adsorization time.
