THE EFFECT OF POLYDISPERSE CONCRETE SCRAP OF 3D PRINTING ON THE STRUCTURE FORMATION OF CONCRETE

Autor: N.M. Tolypina, D.A. Tolypin

Publikováno v: Bulletin of Belgorod State Technological University named after. V. G. Shukhov. 6:17-23

The article considers the influence of polydisperse concrete scrap of 3D printing on the structure formation of concrete during its repeated application. It is established that the favorable effect on the strength is due to the presence of thin layer

Improving Performance of Water-Reducing Admixtures by Modification of Quartz Sands with Electrolyte

Autor: Sh. M. Rakhimbayev, N.M. Tolypina, E. N. Khakhaleva

Publikováno v: Materials Science Forum. 945:141-146

It is widely known that modern anionic surfactants are adsorbed at positively charged active centers of hydrate phases in portland cement that leads to floccules decomposition as well as a release of immobilized water, therefore increasing cement pas

The Role and Significance of Electric and Surface Properties of Mineral Filler in Increasing the Frost Resistance of Powder Concretes

Autor: N.M. Tolypina, Sh. M. Rakhimbayev, A. A. Kosinova, E. N. Khakhaleva

Publikováno v: Lecture Notes in Civil Engineering ISBN: 9783030689834

The influence of mineral fillers with positively and negatively charged electric and surface properties on the frost resistance of powder concretes is studied. The authors put forward a hypothesis that in the processes of hydration and corrosion, whe

OPTIMIZATION OF CEMENT TYPE SELECTION PROCESS FOR PRODUCTS IN AGGRESSIVE ENVIRONMENTS

Autor: N.M. Tolypina, E. N. Khakhaleva, Shark Rahimbaev, D.A. Tolypin

Publikováno v: Bulletin of Belgorod State Technological University named after. V. G. Shukhov. 3:18-23

Currently, in industrialized countries in order to prevent corrosion of the hydration-hardened building products a tendency to use methods reducing the permeability of concrete to aggressive agents of the environment is applied. The authors believe t
