Concrete Creep Data

THE subject of creep occupies an important, place in the literature on concrete of recent years. Creep is the non-elastic deformation which, under sustained load, will increase for several years with a magnitude of several times the initial elastic strain on loading. The major part of this deformation is due to colloidal seepage and so is not really a true creep in the accepted sense. In unstressed concrete, shrinkage is largely due to the same cause, but under stress the seepage is accelerated; colloidal water is forced out of the gel under pressure into the capillary channels and thence to the surface where it is evaporated and an increased deformation is the result.
