1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Durability of construction materials modified by polymeric additives Kuzmin S.A. a ,Egorova A.D. a ,Krasilnikov D.A. a , Emelianova Z.V. a, * a Ammosov’s North –Eastern federal University, 58, Belinskiy str.,Yakutsk 677000, Russia Abstract Nowadays the main materials for construction of buildings and other objects are considered concrete, brick, tree and et al. Increase in operational characteristics of these materials is a priority problem of modern scientific research. Frequent transitions through zero degrees during autumn and spring seasons, other aggressive factors very much affect a state and safety of construction materials. This work presents experience of modification of heavy M200 concrete, wood, arbolite based on local raw materials of Yakutia modified by polymeric impregnations of "Silor-Ultra". As a result, new experimental data were obtained on the increase in the strength characteristics of these materials under concrete and arbolite compression, wood compression and its bending. The paper shows that the modification of samples of heavy concrete М 200, wood and arbolite, allows to increase the strength of these materials. There was considered the structure of the obtained arbolite with a chip treated with “Silor-Ultra T” composition and also treated with lime milk. It was shown the positive effect of processing chips by impregnation “Silor-Ultra T” before its inclusion into the composition of arbolite, and this relatively made it possible to improve the quality of arbolitic products. It is recommended to use “Silor–Ultra” polymer impregnations to improve the strength properties of structural materials. 1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Durability of construction materials modified by polymeric additives Kuzmin S.A. a ,Egorova A.D. a ,Krasilnikov D.A. a , Emelianova Z.V. a, * a Ammosov’s North –Eastern federal University, 58, Belinskiy str.,Yakutsk 677000, Russia Abstract Nowadays the main materi ls for onstruction of buildings and other objects are co sidered concrete, brick, tree and et al.
