The objective of this work is to calculate the stresses and strains induced into moist concrete during freezing. The applied theory is based on thermodynamics and the theory of elasticity. If no additional salts are dissolved in the pore water the inputs needed in the theory are relative humidity and temperature sated in the sample and inside concrete and evaporable water amount in the pore structure. Theoretical results were compared with the test results. In the test cylinders cured under water the largest tensional stresses in freezing occurred on the surface of the test cylinders both in the axial and tangential direction. [ABSTRACT FROM AUTHOR] |
