Abstract:
A slab on grade is simply a slab constructed on earth or ground. Often these types of slabs
are encountered in the industrial practice. There are several types of slabs on grade
commonly used such as pavement slabs found in footpaths, walk ways, airport runways,
highways, basement floors and bottom slab of swimming pools. The observed behaviour
of these slabs is such that most of them are cracked due to serviceability problems or
construction defects. This study is aimed at investigating the time dependent behaviour
both at short term and long term conditions due to creep, shrinkage of concrete and
relaxation of steel.
