To gain insights into the thermochemical properties of such compounds, C–(N)–S–H and N–A–S–H gels were synthesized with compositions: 0.8≤Ca/Si≤1.2 for the former, and 0.25≤Al/Si≤0.50 (atomic units) for the latter. The gels were characterized using thermogravimetric analysis (\n                    <jats:styled-content style=\"fixed-case\">TGA</jats:styled-content>\n                    ), scanning electron microscopy with energy‐dispersive X‐ray microanalysis (\n                    <jats:styled-content style=\"fixed-case\">SEM</jats:styled-content>\n                    ‐\n                    <jats:styled-content style=\"fixed-case\">EDS</jats:styled-content>\n                    ), and X‐ray diffraction (\n                    <jats:styled-content style=\"fixed-case\">XRD</jats:styled-content>\n                    ).
