he results of a laboratory investigation on the early autogenous shrinkage of high strength concrete, and the possibilities of its reduction, are presented. Such concrete demonstrates signiicant autogenous shrinkage, which should, however, be limited in the early stages of its development in order to prevent the occurrence of cracks and/or drop in the load-carrying capacity of concrete structures.he following possibilities for reducing autogenous shrinkagewere investigated: the use of low-heat cement, a shrinkagereducing admixture, steel ibres, premoistened polypropylene ibres, and presoaked lightweight aggregate. In the case of the use of presoaked natural lightweight aggregate, with a fraction from 2 to mm, the early autogenous shrinkage of one-day-old high strength concrete decreased by about 90%, with no change to the concretes compressive strength in comparison with that of the reference concrete.
