СТИЛИСТИКА АЛТАРНОЙ ПРЕГРАДЫ ВИТЕБСКОГО УСПЕНСКОГО СОБОРА II-ОЙ ПОЛОВИНЫ XVIII – НАЧАЛА XIX ВВ. (по материалам архивных исследований)

Stilistika of altar barrier of the Vitebsk Uspenskogo cathedral XVIII – XIX w. (on materials of the archived researches)

In the article the stylistic analysis of iconostasis of the Uspenskogo cathedral of bazilian’s monastery was conducted in Vitebsk on the saved documents of beginning XIX–XX ww. began. Two periods of existence of iconostasis are exposed. The first is characterized by the original national variant of interpretation of stylistic principles a baroque. Characterized the second by alteration 1844 on a model exemplary project, executed in Saint Petersburg in which style of altar barrier changes fully, national originality is lost. On the example of this iconostasis transformation of stylish changes is traced in architecture of униатских temples, dictated by the confessional policy of the Russian empire on Byelorussian earths.

Estimation of reliability of calculation of reinforced-concrete elements punching strength at use of linear de-pendence for the account of influence of longitudinal reinforcing ratio

For the account of influence of longitudinal reinforcing ratio on a punching strength of reinforced-concrete elements it is offered to use linear de-pendence. The accuracy and reliability estimation and comparison of offered linear dependence to the dependence presented in domestic design code is executed. On the basis of the received results conclusions are drawn and recommendations about application of offered linear dependence at calcu-lation of punching strength of reinforced concrete elements are made.

ВЛИЯНИЕ МИКРОНАПОЛНИТЕЛЯ НА ПРОЦЕССЫ ФОРМИРОВАНИЯ МИКРОСТРУКТУРЫ ЦЕМЕНТНОГО КАМНЯ

The influence of microfiller on the hydrated cement microstructure forming

The influence of inert fine filler on the hydration kinetics of the cement composite is investigated using the software package of simulation and anal-ysis of the composites structure. It is shown that the replacement of some cement clinker by inert filler results in reducing of hydration rate of cement composite and might cause a substantial rising of capillary porosity of material.

РОЛЬ МОДИФИЦИРОВАНИЯ ВОДЫ ЗАТВОРЕНИЯ ДОБАВКОЙ STG-3 В ПРОЦЕССАХ УСКОРЕНИЯ ТВЕРДЕНИЯ ЦЕМЕНТНЫХ БЕТОНОВ

The Role of the STG-3 Modified Mixing Water in the Cement Concrete Hardening Processes

The peat-based chemical additive STG-3, when used within the dosage rate up to the critical micelle concentration to modify the mixing water, has been proved to accelerate the early-stage hardening of cement stone as well as to contribute to a homogeneous and fine-disperse concrete structure of low porosity, resulting in a considerable gain in strength at the early stages of concrete hardening process. Besides, being a steel corrosion inhibitor, the STG-3 activated mixing water enhances the protective proper ties of concrete with respect to its steel reinforcement.
