Currently one of the main materials for the construction of buildings and structures is concrete. Improving the performance of concrete is a priority of modern scientific research. Frequent transitions through zero degrees in the autumn-spring seasons, other aggressive factors greatly affect the condition and safety of building materials. This work presents the experience of modifying heavy concrete M200, polymer additive Amokor KM. The data on increased strength characteristics of materials were obtained as a result of 2 years of field tests.
New realia, phenomena, ideas and technologies that require nomination appear in a constantly changing world almost every day. The covid-19 pandemic has caused a flurry of neologisms in most languages, which has led to the emergence of a rich layer of new coronavirus vocabulary. The article provides its comparative analysis in German, English and Russian, carried out from the point of view of the ways of nominating new coronavirus concepts in these languages.
The paper investigates the strength characteristics during compression and bending at low temperatures of concrete based on local raw materials of Yakutia, and local wood using polymer impregnation «Amokor», as a result of which data on the increase in strength characteristics of the material, the internal structure of modified concrete are obtained.
The study is devoted to the identification of cognitive features of the concept Eltern («parents») in the institutional discourse of German schools of different types. It is shown that the initial scope of the concept presented in lexicographic sources expands in the discourse due to the features actualized with the help of compound words. The highlighted features correspond to the social roles that are assigned to the parents of students in German schools. A conclusion is made about the discursive transformation of the concept Eltern into the concept Eltern eines Schulkindes («parents of a schoolchild»).
USING A POLYMER ADDITIVE AS A WAY TO IMPROVE THE MECHANICAL PROPERTIES OF CONCRETE AND WOOD PRODUCTS
Today, the main materials for constructing buildings and structures are concrete, brick, wood, and metal. Improving the performance characteristics of these materials is a priority task of modern scientific research. The paper presents the experience of modifying heavy concrete М200, М75, and М125 using polymer impregnation «Amocor». Data on the increase in the strength characteristics of the materials under study have been obtained. Tests were conducted on bending within a wide range of climatic temperatures from +20 °C to –60 °C. It was revealed that the strength of unmodified samples decreased at a test temperature of –30 °C, which is explained by the growth of internal stresses. Modification of the samples allowed for the removal of internal stresses.
