The purpose of this study is to compare binders of two different origins. The powders obtained from crushing pure C3S and hydrated cement for 28 days with w/b=0.6 and 0.5, respectively, will be subjected to heat treatment at 800°C. This work used X-ray diffraction (XRD) as a technique to characterize. According to X-ray diffraction, heat treatment resulted in the synthesis of β-C2S belite in the pure phase and two polymorphs α'-C2S and β-C2S in the cement phase. The binder regenerated from cement pastes generates C-S-H at an early stage, which can be attributed to the high reactivity of the α'-C2S polymorph. |
