摘要：

In this article, an extensive experimental and numerical study of self-desiccation and its importance in concrete technology is outlined. For this purpose, cubes and cylinders of eight qualities of concrete were studied at 4 different ages for each one. Parallel studies of autogeneous shrinkage, basic creep, hydration, internal relative humidity and strength were carried out. Previous research in the field is summed up. Finally, the article presents the mechanisms of self-desiccation as well as its importance in concrete technology by modelling the autogenous shrinkage and its effect on basic creep. This project was carried out between the years 1992 and 1995.
