TL;DR: In this article, the effects of the solid/liquid and SiO 2 /Na 2 O ratios on the properties of metakaolin-based geopolymers were investigated, and it was shown that TFT-LCD waste glass consisting of SiO2 and Al 2 O 3 had a compressive strength of 62 MPa after 60 days of curing.

TL;DR: In this paper, the performance of geopolymer concrete was investigated using blended ash of pulverized fuel ash and palm oil fuel ash from agroindustrial waste along with alkaline activators for up to 18 months.
Abstract: The aim of this study is to investigate the performance of geopolymer concrete prepared using blended ash of pulverized fuel ash and palm oil fuel ash from agroindustrial waste along with alkaline activators when exposed to a 5% sodium sulphate solution for up to 18 months. Ordinary portland cement (OPC) concrete was also prepared as the control concrete. The main parameters studied were the evaluation of mass change, compressive strength, products of degradation, and microstructural changes. The deterioration was examined using X-ray diffraction (XRD), a Fourier transform infrared spectroscopy (FTIR), a thermogravimetry analyzer (TGA), and a field emission scanning electron microscope (FESEM). The results of geopolymer and OPC concretes were compared and discussed. The compressive strength of geopolymer concrete, when exposed to a 5% sodium sulphate solution for more than 1 year, was superior to that of OPC concrete. These materials could be used for making sulphate-resistant concretes, attributa...
