Compressive creep test rigs


General Information


BATir - Building, Architecture & Town Planning, building : C, local : civil engineering lab level 1

Key words:

Concrete / Compression

Main application:

Compressive creep rigs were developed for testing concrete in compression under constant loading. The load is applied on the sample by increasing flat jack pressure with a pump. Once the target pressure is obtained, the pump is disconnected. A cell force is placed on the top of the sample. The measurements of the displacements are taken in the central part of the specimen where the stress field is assumed to be homogenous. Displacements are measured with an extensometer. A dummy specimen is used for each series of test to monitor the thermal and shrinkage strains. The measurement of the displacement and the force are sent to a computer for data recording. Tests are carried out in a climatic room with temperature and relative humidity controls. It is also possible to monitor the damage in the sample with the acoustic emission.
