It has long been understood that creep and desiccation-driven shrinkage of concrete are coupled phenomena. Many mechanisms have been proposed over the past six decades by which creep and shrinkage are intertwined. Here, we propose that dissolution of solid, microscale constituents while under a ...

摘要: The recently developed mkaoprestress-solidifioation theory on concrete creep and shrinkage is based on the current knowledge of the physical mechanisms involved. This theory was shown to provide optimal agreement with the full variety of the available...

This paper presents expressions for estimating creep and shrinkage of concrete and lightweight aggregate concrete using mathematical statistics and superposition of influential factors based on Chinese law materials and through tests. The expressions include mainly the basic formulas of creep and shrinkage ...

representation of the different physical mechanisms. Basic creep appears when the concrete is prevented from drying, and drying creep is the additional creep that occurs due to the drying process. The division into two components is necessary to accurately describe delayed deformations in high...
In this case, the machine is not able to adopt the tensile train shrinkage as the temperature goes down, resulting in severe overloading. This may destroy the specimen or the stress sensor; at least, the microstructure of the material is changed, which makes the test unusable. In contrast,...
