Journal ArticleDOI
Mechanical and thermal properties of fly ash based geopolymers
TL;DR: In this article, an experimental investigation on the thermo-mechanical properties of geopolymers prepared using a class F fly ash, KOH and Na2SiO3 is presented.
Journal ArticleDOI
Mechanical properties and microstructure of graphene oxide cement-based composites
TL;DR: In this article, the effects of the GO content and water/cement ratio on the mechanical properties and microstructure of GO-cement composites were systematically investigated through experimental tests.
Journal ArticleDOI
Feasibility Study of Loess Stabilization with Fly Ash–Based Geopolymer
TL;DR: In this paper, an experimental study of applying fly ash-based geopolymers for the loess stabilization is presented. And the microstructural characterization unveils that a compact and stable...
Journal ArticleDOI
Experimental Study of the Geopolymeric Recycled Aggregate Concrete
TL;DR: The mechanical study shows that the reduction rates of the compressive strength, Young's modulus, and the Poisson’s ratio of the geopolymeric recycled aggregate concrete (GRAC) specimens increase with the increase of the water/cement (w/c) ratio.
Journal ArticleDOI
Microstructure and microhardness property of the interface between a metakaolin/GGBFS-based geopolymer paste and granite aggregate
TL;DR: In this article, the microstructure and properties of the interface zone in geopolymeric concrete are investigated, and the results indicate that the bond strength between the geopolymer and aggregate is higher than that between the cement paste and granite aggregate, and it decreases with the increase of the activator modulus and liquid/solid ratio.
