Influence of alumina and glass microsphere on composite material fire-resistance have investigated. Microsphere have added in composite material on the base of phenol-aldehyde resin and carbon material. It was determined that alumina microsphere in quantity 20% increase fire-resistance on fifty percent, glass microsphere in the same quantity reduce fire-resistance on fifty percent.

Аccelerated test program of coating age evaluation have developed. A main target of the program was selection the most rust-resistant protective coating for underground piping of heating network in Belarus weather conditions. Thermostability, thermo and humidity resistance, corrosion environ-ment resistance were the basic selection criteria.
