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.

Geopolymer Concrete with Lightweight Artificial Aggregates

Materials, 2022
This article presents the physical and mechanical properties of geopolymer concrete with lightweight artificial aggregate. A research experiment where the influence of fly ash–slag mix (FA-S), as part of a pozzolanic additive, on the properties of geopolymers was carried out and the most favorable molar concentration of sodium hydroxide solution was ...

Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers [PDF]

, 2018
Chemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer and they remain for 28 days ...

Flexural Test of Fly Ash based Geopolimer Concrete Beams

MATEC Web of Conferences, 2017
Fly ash is a by-product from the coal industry, which is widely available in Indonesia. Fly ash contains quite high silicate and alumina. Silica and alumina reacts with alkaline solution to produce alumina silicate gel which binds the aggregate to ...

Behaviour of ambient cured prestressed and non-prestressed geopolymer concrete beams

Case Studies in Construction Materials, 2022
One of the sustainable alternatives to Portland cement is geopolymer concrete consisting of industrial waste. Practical application of geopolymer concrete is restricted as it requires the use of high temperature to develop compressive strength.
