Effect of thermal induced stress of concrete on performance characteristics of constructions

Abstract

The article discusses issues related to determining and taking into account own thermally stressed state, which is formed in concrete during hardening, and is used to provide the required consumer properties of concrete during the construction of the Crimean bridge. It’s relevant in view of the tight construction timeframe for the said facility in rough terrain and hot climate. It is known that the location of a massive object in salty seawater, a hot climate, an increased seismic hazard, the presence of ice loads in the winter period of time, a large strait depth and other factors required a serious approach to ensuring the quality of concrete work and increasing the durability of the structure. The paper presents the results of own thermally stressed state of hardening concrete when determining the permissible temperature gradient in it, which made it possible to speed up the process of building the object while observing the necessary properties. This question seems relevant due to short deadlines, construction of the specified facility in adverse conditions, and also taking into account the development in our country construction of unique non-class objects.
