WebApr 20, 2024 · The hydration behaviors of Portland cement with ATMP and SG were investigated by the means of isothermal calorimetry measurements, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscope (SEM). The results showed that the retarding effect of ATMP was much intensive than SG, especially in the … A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a raster scan pattern, and the p…
