Drying Shrinkage of Concrete Elements

Popis výsledku v původním jazyce

The paper deals with shrinkage of large concrete specimens. The segments of walls of the thicknesses 200 mm, 400 mm and 800 mm were cast. Four sides were sealed in order to simulate the drying of the infinite walls of different thicknesses. The elements are equipped with vibrating wire strain gauges which measure strains inside the elements. The strains in vertical as well as in horizontal directions have been recorded for the period of 6 months. The segments of walls are stored in a laboratory. Relative humidity and temperature of the environment are not controlled, but recorded very closely. Additional tests have been executed. The concrete compression strength was measured on cubes and uniaxial shrinkage is measured on standard cylinders using embedded vibrating wire strain gauges. The cylinders are stored in three different environments, in the laboratory and in the rooms with controlled relative humidity of 65 % and 100 %, respectively. A comparison of measured shrinkage with various shrinkage models is provided (Model Code 2010, Eurocode 2, Model B3, Model B4, Model B4s and Model ACI 209R-92).
