Figure 3
Schematic diagram that illustrates the nature of the linear aluminosilicate chains in C-S-H. The unfilled triangles represent Si—O tetrahedra and the shaded triangle represents an Al—O tetrahedron. Q2 = Q2P; Q2 is sometimes written as Q2(0Al) to indicate the lack of Al at one of the two adjacent tetrahedral sites. v = vacant tetrahedral site. |
