Conclusions
New principles of a process for making unfired ceramic materials using strengthening by chemical activation of contact bonds (CACB ceramic) have been formulated. Additional strengthening of ceramic materials is achieved with virtually unchanged porosity, i.e., without filling the pore space and clearly with the retention of the original geometrical system of contact bonds.
The mechanical properties of the SCACB ceramic are fully comparable with the properties of the fired materials. By comparison with other unfired ceramics or refractory materials obtained using various binders or bondings (phosphate, silicoorganic, water glass, alumina, cement, resins, etc.), the structure of the SCACB ceramic which on the whole determines the properties of the ceramic, is outstanding in its low concentration or virtual absence of additional components.
It would be sensible to carry out some studies to give a fuller explanation of the strengthening process and also how to introduce into production unfired materials of this type.
