TL;DR: In this paper, ground fly ash (GFA), with a median particle size of 10.5μm, was used as source material for making geopolymers cured at room temperature, and compressive strength tests and microstructure observations using SEM, EDX, XRD and FTIR were performed.
Journal ArticleDOI
Workability and strength of coarse high calcium fly ash geopolymer
TL;DR: In this article, the basic properties viz., workability and strength of geopolymer mortar made from coarse lignite high calcium fly ash were investigated, and the results revealed that the workable flow of the geopolymers was in the range of 110 −±5% −135 −± 5% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH.
Journal ArticleDOI
Influence of NaOH solution on the synthesis of fly ash geopolymer
Journal ArticleDOI
Comparative study on the characteristics of fly ash and bottom ash geopolymers.
TL;DR: The results show that both fly ash and bottom ash can be utilized as source materials for the production of geopolymers and the moderate NaOH concentration of 10 M is found to be suitable and gives fly ashand bottom ash geopolymer mortars with compressive strengths of 35 and 18 MPa.
Journal ArticleDOI
Effect of fly ash fineness on compressive strength and pore size of blended cement paste
TL;DR: In this paper, the effect of fly ash fineness on compressive strength, porosity, and pore size distribution of hardened cement pastes was investigated and it was shown that the blended cement paste with classified fly ash produced paste with higher compressive power than that with original fly ash.
