TL;DR: In this paper, the effects of pH value on the hydrate phase, morphology and microstructure of cement hydration products under sulfate attack were characterized in combination with XRD, SEM-EDS, 1H, 27Al and 29Si NMR.

TL;DR: In this article, 29Si and 27Al MAS NMR spectroscopy combined with SEM-EDS techniques were utilized to investigate the microstructure of Portland cement paste (PC) and PC with granulated blast furnace slag (PC-GBFS) curing in both water and the sulfate sodium solution during 365 days.

TL;DR: In this paper, a smart organic polymer with hydrophilic and hydrophobic components is designed as corrosion inhibitors, and a combination of experiments and molecular dynamics simulations is employed to investigate the effect of this smart polymer-based corrosion inhibitor on cement-slag composite pastes under seawater erosion.

TL;DR: Fly ash, a supplementary cementitious material, is normally used in conjunction with portland cement to improve the durability properties of concrete in the field, such as sea-crossing bridings.

TL;DR: In this paper, the degradation mechanism induced by MgCl2 attack at nanoscale is investigated for cement paste exposed to MgC2 solution with different concentrations for 28 and 180 days by combing X-ray diffraction (XRD), 29Si and 27Al Nuclear Magnetic Resonance Spectroscopy (NMR), Scanning electron microscope-energy dispersive spectrometer (SEM-EDS) and thermodynamic modeling.
