A THEORY FOR THE DEFORMATION AND FAILURE OF CEMENT PASTES, MORTARS AND CONCRETES UNDER GENERAL STATES OF STRESS

A theory is presented for predicting the time dependent deformation and failure of cementitious materials under general states of stress. The material is considered to be composed of a large number of anisotropic discrete elements after brandtzaeg. Simple but reasonable laws governing the time dependent anisotropic behavior of these elements are introduced, and it is shown how an assemblage of such elements may create internal tensions under imposed compressive stress states. The production of this tension can explain many observed features of behavior in uniaxial, biaxial and triaxial stress fields. Good correlations between computed and experimental behaviors are demonstrated. /Author/
