Although the formation of zeolites in geopolymers have been mentioned in many works, a
particular interest in geopolymer-zeolite composites started to increase very recently. Such …

Toxic heavy metal ions, as one of the most common pollutants in wastewater, are harmful
and widespread, which have severely threatened human health and survival. Therefore, the …

Carbon capture and storage technology is used to decrease the emission of greenhouse
gases (GHGs) and mitigate climate change. Geopolymers are versatile inorganic materials …

In this work the influence of the activator concentration on the inorganic polymer structure
based on metakaolin was investigated. Changes in the aluminosilicate structure of the …

Portland cement production is related to environmental problems and corresponds to about
6–8% of CO 2 emission. Thus, it is necessary to search for sustainable material. Among …

Geopolymers are alkaline cements composed of aluminosilicate units. The molecular
structure of some geopolymers is sodium-aluminosilicate hydrate (NASH). Impurities …

Application of efficient technologies is imperative to minimize the impact of textile effluents
on the environment. A solution to this problem is the application of molecular sieves such as …

A new method for preparing geopolymer filtrations was suggested, using silica fume in an
alkali activator as an environmentally and economically sustainable material. The …

This present work investigates the effect of the solid-to-liquid (S/L) ratio on the preparation of
metakaolin geopolymer. Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) were …

A study was undertaken into the preparation and properties of fly-ash-based geopolymers
that can be used to make multistage-pore materials able to adsorb gases such as carbon …
