With the help 7-th the factorial plan of the second order the structure of geocement of a kind (0.24-0.26-0.28K2O+0.72-0.74-0.76Na2O)•Al2O3 (4-5-5)SiO2 (15-18-21) H2O on a basis water potash glass is optimized. Introduction in optimum structure of geocement of additives C2F and fossil meal in quantity of 10 % promotes the directed synthesis potash-ferriferous hydromica and high siliceous phases of type zhismondine and flokite. Mathematical models of boundary temperature constancy in an interval 100-1000оС are developed and corrosion cost bones of geocement coverings from action of excited environments in a range рН from 3 up to 5. The decision of the differential equations of parabolic type (the first regional problem) allows to define changes of gradients of temperatures and concentration of excited environments during the different moments of time on depth of a sheeting from the beginning of thermal and aggressive influences. Results of the given work are approved on Skvira (Kiev region) brick-works - drawing on roasting trolley of a tyre-tread covering the action proof to action of aggressive oven gases; and at reconstruction bell tower the Dormition Cathedral in historical and cultural reserve Kievo-Pecherskaja of laurels - protection metalware from action of a damp gas atmosphere.
