Calcium Silicate as a chemical additive is found that it will act as a good compaction aid between the soil particles, and it is very soluble in water. The images obtained by scanning electron microscopy (SEM) show the elemental composition of the most representative samples based on the percentile of atoms: Figure 7: Image of the sample 1 as raw laterite from the Thiadiaye site © 2023 Global Journals Global Journal of Researches in Engineering ( ) E Volume XxXIII Issue II Version I 53 Year 2023 Stabilization of a Sub-Saharan Laterite Soil using Calcium Silicate APPENDICE in T erms of E lemental C omposition for L aterites 10.
