Especially for prestress concrete, creep induced prestress loss puts severe threat on the safety and durability of prestressed structures. Thus, in order to thoroughly understand the creep characteristics of the typical concrete mixtures used in Florida, this project was carried out by University of ...
The observed behavior of concrete is reported and the possible theoretical treatments are discussed with an eye to their satisfying the practical demand for an optimum between simplicity and reality. Some general characteristics of creep are first described, then the creep-stress-time under load-age ...
This study aimed to evaluate the short-term creep deformation of high-strength concrete with varying fly ash replacement ratios using the gradation loading test method. The creep mechanical properties and failure characteristics of the concrete samples were determined by analyzing the creep-time curves,...
The creep characteristics and internal relative humidity (IRH) of concrete with shrinkage reducing admixtures (SRA), poly vinyl alcohol fiber (PVAF) and a mixture of fly ash and slag (MFS) were investigated by the self-made loading device. The pore structure was tested, and the relationship of...

In mass concrete structures, such as concrete dams, creep can reduce the temperature stress as well as delay cracking, and it is thus an important factor that cannot be neglected when calculating the thermal stress of concrete dams [1]. In order to study the creep characteristics of concrete,...
Due to the difficulties associated with measuring tensile creep, limited research has been undertaken to quantify the direct tensile creep characteristics of concrete at early-ages. Some researchers [1], [2], [3], [4] have used uniaxially restrained shrinkage tests to indirectly measure the ...
