Abstract
An analysis is presented for the process and for the solution of a problem dealing with the distribution of moisture in a body in the diffusion drying of concrete; consideration is given to the effect of gravitation under conditions in which there is no hydration, carbonation, and aging in the material; moreover, the transport coeffients are constants.

Additional information
The author has been engaged since 1961 at the State Institute for Technical Research (Helsinki, Finland) on the topic: “The Drying of Concrete” [1]. A brief outline of the completed research on the effect of gravitation on the process of drying concrete was published in “A Theoretical Investigation of the Effect of Gravitation on Drying of Concrete. Two Solutions of a Diffusion-Type Equation, with Consideration of the Gravitation Component” by Pihlajavaara and Rant (State Institute for Technical Research, no. 94, Helsinki, 1965). This article is a somewhat modified portion of the latter publication, including a section of the chapter entitled “Physics,” a summary of the formulas from the chapter entitled “Mathematics” (without derivation of the formulas, which was the work of Dr. Rant), and certain of the nomograms from the chapter entitled “Numerical Examples.”
The translation by T. S. Kortneva was edited by Doctor of Technical Sciences Yu. A. Mikhailov and Candidate of Technical Sciences V. A. Sheiman.
