【 摘 要 】

The article discusses the feasibility of usage of fly ashes from the Primorsky region heat power plants in production of fibre-reinforced concrete with improved impermeability characteristics. Based on the fact that ashes created by the Primorsky region heat power stations are chemically applicable as the filler in concrete composition, those of four Primorsky region heat power plants were analyzed. It is found that ashes of Vladivostokskaya HPP-2 and Artyemovskaya HPP comply with the required indicators of specific effective activity and can be classified as the first class materials applied in all kinds of construction operations. The development of the composition binder involving acidulous ash is the most promising.
