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 ...
