Structural and material performance of geopolymer concrete: A review
TL;DR: In this paper, the authors reviewed the material and structural performances of geopolymer concrete to identify the research gaps in this area for future research development, and showed that the structural properties of the concrete can be improved by using more structural elements and more desirable structural performances compared with conventional counterparts.

Hybrid life cycle assessment of greenhouse gas emissions from cement, concrete and geopolymer concrete in Australia
TL;DR: In this paper, an input-output based hybrid life cycle assessment method is used for these products, which resulted in higher greenhouse gas emissions for ordinary Portland cement and all types of concrete due to the methodology incorporating an economywide system boundary, which includes the emissions from upstream processes.

Resistance of geopolymer materials to acid attack
TL;DR: In this article, the degradation of geopolymer materials using a class F fly ash (FA) and alkaline activators when exposed to 5% solutions of acetic and sulfuric acids was studied using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).
Journal ArticleDOI
Durability of Geopolymer Materials in Sodium and Magnesium Sulfate Solutions
TL;DR: In this paper, the authors investigated the durability of geopolymer materials manufactured using class F fly ash and alkaline activators when exposed to a sulfate environment and found that the most significant deterioration was observed in the sodium sulfate solution and it appeared to be connected to migration of alkalies into solution.
Journal ArticleDOI
Durability of concrete exposed to leaching and external sulphate attacks
TL;DR: In this paper, a leaching and external sulphate attack on concrete lead to dissolution of hydration products, mainly portlandite, and in case of ingress of sulphate ions to formation of expansive products such as gypsum and ettringite.
