AbstractAbout AuthorsReferences
The article contains the analysis of experiment research in the definition of the joint effect of low negative climatic (up to -70°C) temperature and humidity of concrete (in the range of 3,12 to 5,20%) at the water-cement ratio=0.4 on the transformation of the diagrams of heavy (normal weight) concrete deformation. Developed diagrams are intended for building gen- eral physical ratios as applied to the calculation of reinforced concrete structures which operate under the conditions of simultaneous action of power loads, a significant negative tem- perature and humidity of concrete with the help of modern computational methods (finite element method for example).
