The traditional cement production wastes a large amount of natural resources and energy,
and causes environmental pollution, which cannot meet the green and sustainable …

A very large amount of fly ash is generated from coal combustion, and the high value-added
and efficient utilization conversion of this solid waste into a resource remains an issue to be …

Geopolymers, possessing a semi-crystalline three-dimensional inorganic network generated
by the dissolution and reaction of a solid alumino-silicate source with an activating solution …

As the raw material of geopolymer, F-class fly ash (FFA) often needs strong alkali such as
NaOH to stimulate due to its low reactivity. In this study, FFA was refined and activated by a …

Geopolymer (also called inorganic polymers) is a kind of amorphous gel material with a 3D
structure consisting of SiO4 and AlO4 tetrahedra. It has drawn international attention due to …

This study focused on the optimization of the production conditions of an ultrahigh expanded
perlite lightweight aggregate-filled fly ash-based geopolymer composite and the …

Geopolymer foams (GFs), in which macro-porosity is introduced on purpose into the micro-
and meso-porous geopolymer matrix, have received wide interests as for energy …

Rheology is a powerful tool to assess the fresh properties of cementitious systems
accurately. However, uncertainties and systematic errors in measurements can impact the …

In the study, the recycled clay brick powder/fine soil powder-based sodium hydroxide alkali-
activated mortar (AAM) specimens were prepared by mixing different percentages (100/0 …

Geopolymer as an alternative to cement has gained increasing attention. The aim of this
article is to study the influence of the silica fume content and activator type on the porous fly …
