1, the analysis method is very simple, EDS energy spectrum has the function of direct quantitative analysis, in order to be accurate, we can analyze more points (more than 20 points) and take the average value.

2.EDS is a qualitative analysis, and its results can only be used as a reference. Surface analysis is relatively better, but it cannot be used as quantitative analysis.

3.EDS analysis is to analyze the types of elements and use different X-ray photon characteristic energies of different elements for composition analysis. The main hydration products of fully hydrated cement paste are: 1) hydrated calcium silicate gel (C-S-H) is about 70%.
