Sažetak
Results obtained by testing shrinkage deformation on ten groups of concrete, using the total of thirty one mixtures, are presented in the paper. Concrete groups differed according to the quantity of water and mineral and chemical admixtures. In this way, a wide range of concrete compressive strength values, from normal concrete to high strength concrete, was obtained, in addition to different consistency values. The shrinkage of concrete specimens after a two-day cure in water was monitored over a period of more than one year. An another series of twenty-nine concrete mixtures was also prepared to monitor the autogenous shrinkage of concrete. The total shrinkage of concrete was defined as the sum of the autogenous shrinkage of concrete at one day of age, and the shrinkage of concrete after the end of curing. In this paper, the model was developed and used in order to predict concrete shrinkage values after initial curing, and total shrinkage values, as related to compressive strength of concrete.
