Highly porous mullite ceramics from engineered alkali activated suspensions [PDF]

, 2018
Air may be easily incorporated by vigorous mechanical stirring, with the help of surfactants, of activated geopolymer-yielding suspensions. The cellular structure is stabilized by the viscosity increase caused by curing reactions, configuring an ...

Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]

, 2018
The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.

Bioactive glass-ceramic scaffolds from novel 'inorganic gel casting' and sinter-crystallization [PDF]

, 2017
Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the ...

Performance of laterite-based geopolymers reinforced with sugarcane bagasse fibers

Case Studies in Construction Materials, 2021
In this study, sugarcane bagasse fibres (SBF) were used as a sustainable alternative to reinforce laterite-based geopolymers. As geopolymers can be deemed an eco-friendly construction material, the sustainability of geopolymers can be further improved ...

Study on Structure and Properties of Kaolin Composites- based Geopolymers

Chemical Engineering Transactions, 2018
In order to study the pore structure and corrosion resistance of kaolin composite-based geopolymers, in this paper, kaolin composite-based geopolymers were prepared by replacing fly ash with 15%, 25%, 35%, 50%, and 60% kaolin.

Geopolymer Concrete

International Journal of Advanced Research in Science, Communication and Technology
Geopolymer concrete (GPC) is an emerging eco-friendly alternative to Ordinary Portland Cement (OPC), offering reduced carbon emissions and superior durability. In India, with its vast availability of fly ash, slag, and rice husk ash, GPC presents a unique opportunity to address environmental challenges while promoting sustainable development.

Synthesis of clay geopolymers using olive pomace fly ash as an alternative activator. Influence of the additional commercial alkaline activator used

Journal of Materials Research and Technology, 2021
In this research, the use of olive pomace fly ash (OPFA) as an alkaline source for the activation of calcined clays (CC) from Bailén (Jaén, Spain) was studied. The optimal composition was obtained for 70 wt % CC and 30 wt % OPFA. The physical, mechanical

Porous glass-ceramics from alkali activation and sinter-crystallization of mixtures of waste glass and residues from plasma processing of municipal solid waste [PDF]

, 2018
Alkali-activated aqueous slurries of fine glass powders, mostly deriving from the plasma processing of municipal solid waste ('Plasmastone'), were found to undergo progressive hardening at low temperature (75 degrees C) owing to the formation of C-S-H ...
