Abstract:

Most theories on the time-dependent volume changes of concrete structures assume that when load is applied there is an initial elastic deformation followed by a long-term inelastic deformation. In reality, it is the instantaneous deformation that is seriously complicated by inelastic effects. Deformations at 1 year can be calculated with greater certainty than instantaneous deformations. The multiplicity of creep data in the literature, practically all of which are applicable only to a specific set of conditions and of no general use, is the result of the multiplicity of available aggregates. But the only properties of aggregates that influence creep of concrete are elastic properties and concentration, and these can be determined in 1 day. If there were a comprehensive data bank of creep behavior of cement pastes of various water-cement ratios and various degrees of hydration exposed to various ambient conditions, a designer would merely need to request a quick aggregate test to produce a good first approximation of volume change behavior of the structure. /Author/
