| Popis: | Summary: Attention is drawn to our lack of knowledge of the laws of the deformation of concrete, and examples are given of slabs prestressed in two directions which have carried loads four or five times greater than those predicted by classical computation, without cracks being formed. To explain these and similar cases, the author develops his theory of the constitution of concrete; that it is a complex “solid-liquid” to which the laws of thermodynamics may be applied. This enables general laws to be formulated which explain known experimental results and allow new ones to be predicted. In this way shrinkage, creep, and—in general terms—everything concerning the elastic, plastic, instantaneous and time-dependent deformation of concrete is explained, as well as the well known autogenous healing property of cracked concrete. The paper ends with a discussion of the deformation of concrete in shear. |
