Application of Pozzolan as Materials of Geopolymer Paste
TL;DR: In this article, the effect of increasing the ratio of silica to alumina increase fire resistance ability for both metakaolin and clay in calcination at 700°C was analyzed.
Journal ArticleDOI
The Effects of Na2SiO3/NaOH Ratios on the Volumetric Properties of Fly Ash Geopolymer Artificial Aggregates
TL;DR: In this paper, the influence of the volumetric properties of artificial aggregates made of fly ash to the performance of asphalt mixture to be used in pavement layers was evaluated in a study conducted as a part of a research.
Journal ArticleDOI
Mechanical Properties of Geopolymer Concrete Exposed to Combustion
TL;DR: In this paper, the authors analyzed the mechanical properties of fly ash-based geopolymer concrete after being exposed to high temperature, such as decreasing of the compressive strength, splitting tensile strength, and porosity.

TL;DR: In this paper, the optimum flexural strength of 86.833 MPa is obtained when the ratios of Na2SiO3/NaOH is 0.24 with the NaOH concentration of 12M at 1200 °C.
Journal ArticleDOI
Effect of Activators on Strength of Hybrid Alkaline Cement
TL;DR: In this article, an experimental analysis of alkali activators effect on strength of hybrid alkaline cement produced from 80% fly ash and 20% ordinary Portland cement was performed and it was concluded that addition of soluble silicate on the dry mix of hybrid cement-sodium sulfate activator reduce compressive strength and shorten the setting time.
