Introduction Most construction works require soil as the earth's foundation on which engineering structures are laid.
The pozzolan potential of cow bone ash has been advanced, but this is not without a disadvantage in that the calcination of cow bone is not energy and cost-friendly [10].
This behaviour infers that most of the soil samples need to be stabilized to improve their engineering properties.

The main chemical reactions involved in the experiment are as follows: Zn + 3NH4OH + NH4HCO3= Zn(NH3)4CO3 +3 H2O+ H2↑ (1) Me2+ + Zn = Me↓+Zn2+ (Me as impurity element) (2) Zn(NH3)4CO3 + H2O → ZnCO3·3Zn(OH)2 ↓ + NH3↑ + CO2↑ (3) ZnCO3·3Zn(OH)2 → ZnO + H2O + CO2↑ (4) Characterization X-ray diffraction analysis was carried out on D8 advance X-ray diffractometer (Cu-Kα, λ=0.15406nm).

Two engineering approaches to predicting scale cracking can be made leading to two differing consequences.
The major thrust of his approach is to recognise that ideally all these factors will need to be incorporated into a predictive methodology that enables the conditions for spallation to be determined in an engineering context.
