The increasing compressive strength by 25,0-29,5 % and wetting contact angle - by 49,5-53,9 % as well as reduction in water absorption - by 85,4% and reducing the depth of destruction under the action of hydrochloric acid by 45,5- 55.6 % (10 % solution), and 41,7-55,0 % (20 % solution) have been observed. The efficiency of radiation-chemical modification has been established. The act of using the results of research work in the national economy has been received. The technology can be utilized to protect against destruction of concrete structures, for example, in cooling stacks, nuclear stations Product Description popup.authors Григор'єва Ольга Петрівна Старостенко Ольга Миколаївна popup.nrat_date 2020-04-02 Close
