Table 2 tabulates the chemical composition of the starting materials that formed zeolite.
It is well known that the porosity affects the strength of ceramic and cementitious materials.
The strength of the materials listed in Table 3 are not suitable for concrete application but they can be applied as absorbent or templating materials.
