These local materials are abundantly available in nature but have not been used, which are utilized together to produce hybrid high-strength concrete.
Using such materials leads obviously to expensive cost.
Methods for the chemical composition testing of substitution materials used and the results are given in Table 1.

Based on the general regularities of β-C2S and α’-C2S interaction with aluminate solutions, one could expect the influence of structural features of different types of sinters based on various alkali-aluminate raw materials on silica transition into aluminate solutions.
Due to the disordered structure of α’-C2S (high content of small particles, fragments), a high level of oversaturation of SiO2 in the solution quickly occurs with respect to the metastable equilibrium of Na2O – Al2O3 – SiO2 – H2O, similar to how, for example, oversaturation with SiO2 in an alumina solution occurs when it interacts with active forms of silicon containing materials - hydrargillite bauxite, silicicic acid [2, 3].
At the rapid creation of significant oversaturation with SiO2 in the alumina solution (due to the active silicon-containing materials) unstable in this range of concentrations of bonds [Al - O - Si] may occur, which lead to the formation of alumina-silicon associates (sodium hydroaluminosilicate prototype) and crystallization of sodium hydroaluminosilicate, the system "eats" the excess silica and returns to the metastable state with the participation of simple hydrated silicon and aluminum ions.
