This study was carried out to check whether the shrinkage can be reduced by using mineral admixtures and the shrinkage behavior of concrete containing mineral admixtures in actual environmental conditions. Since there are several environmental factors affecting on this shrinkage of concrete. Observation of shrinkage cracks in concrete structures is the most important aspect. Other than the observed data, it was necessary to get the predicted measurements of shrinkage from specific codes and models. But all these equations and models have been modeled in specific environmental situations. For most of them temperature and relative humidity values have taken as constants or under the control lab conditions. These codes or equations don’t represent the exact situation for the structures in the local environmental conditions. Therefore in this study, one of the main aims is to find out, which model or code equation gives the most relevant relationship for the shrinkage strain in structures under actual environmental conditions
