Abstract: Geopolymers have been employed as a replacement material for cement in construction because they are better for the environment than are other replacement material options. In recent decades, externally bonded carbon ...

Abstract: Enamel coating is a novel type of coating for the corrosion protection of reinforcement in concrete. Recently, improved enamel coating was achieved using low-temperature sintering. This study aims to investigate the effect ...

Abstract: In this study, we investigated the degradation process of metakaolin-based geopolymers exposed to high temperatures up to 1,000°C. The changes in mechanical properties, microstructure, and phase assemblage of the samples ...

Abstract: This study investigates the effect of silica moduli (SiO2/Na2O ratio) of alkaline activators on the degradation mechanisms of fly ash–based geopolymer (FAG) mortars that are exposed to elevated temperatures of up to 1,000°C. ...

Abstract: The phase structure and corrosion resistance of uncoated, pure enamel-, double-enamel- and triple-enamel-coated hot-rolled plain steel bars were investigated by X-ray diffraction (XRD), laser microscopic Raman spectroscopy, ...

Abstract: This study utilized a heat-moisture coupling model to characterize the internal microenvironment of concrete and establish the relationship between environmental temperature, humidity, external chloride ions, corrosion ...
