... concrete protectant, polyurea, epoxy resin and silane, were applied to concrete samples in various amounts. One-sided freeze–thaw cycle experiments, wear tests and flame ablation tests, along with scanning electron microscopy to observe morphologies, were carried out on these four coatings and the uncoated...

... studies (porosity, sorptivity, rapid chloride permeability and accelerated corrosion permeability tests). Microstructural analyses studies (X-ray diffraction analysis and scanning electron microscopy) were conducted to confirm the results obtained from the macrostructural studies. Two grades of concretes...

...Ana Mafalda Matos; Joana Sousa-Coutinho Illustrating the important potential role of scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDX) in concrete durability research, the aim of this study is to observe the effect of glass powder in mortar exposed...

.... Scanning electron microscopy (SEM) was used to determine the morphology, crystal size and amount of ettringite formed. From each sample, at least five different sample regions were looked at to ensure that only representative images were evaluated. Generally, images were captured at magnifications of 5000...
