Creep and Shrinkage in Concrete Containing Mineral Admixtures

A Predicting delayed strains (creep and shrinkage) in concrete proves to be critical to a large number of pre-stressed concrete structures, such as containment vessels of nuclear power plants, post-tensioned bridge girders, etc. These delayed strains include two components of shrinkage, namely, Autogeneous shrinkage and Drying shrinkage and two components of creep strains, namely, Basic creep and Drying creep. The present study focuses to predict the creep and shrinkage of Self Compacted Concrete (SCC) and High volume fly ash normal concrete experimentally. And a Hygro thermo chemo mechanical model (D.Gawin et al, 2006) is implemented to estimate gaseous pressure, capillary pressure and temperature and displacements which in turn varies with the hydration process. The Solidification theory proposed by Bazent (Bazant and Prasannan, 1989), is used to estimate the creep and shrinkage.
