Fly ash is an active mineral admixture used commonly in the production of blended Portland cement. Fly ash improves many important properties of cement and cement concrete: increasing late compressive strength, increasing sulfate resistance, reducing heat of hydration, reducing alkali-silica reaction and reducing water permeability.

Most of the megacity placed in large delta plan systems worldwide have very active building activities. Those delta plan systems composed of unconsolidated sediments which have a high content of groundwater and hydraulically connected with dense surface water bodies. The new twintower of 108 Military Central Hospital foundation covers 13.500m2 and excavate down to 16m below ground surface. The foundation and basements of the building placed in clay and sand layer of Holocene aquifer.

We performed a theoretical study, at the BLYP/aug-cc-pVDZ theoretical level, of the mechanisms of H-transfer between biologically relevant tautomers of cytosine and guanine. The analysis of the ground- and excited state energy barriers of the conversions showed that in some cases they are lower as compared to the ground state reactions. The inclusion of one water molecule as a catalyst in the oxo-amino form of cytosine and guanine drastically changes the mechanism of the reactions in the ground as well as in the excited state.
