Autogenous shrinkage of concrete is a result of self-desiccation in the pores of cement paste and can
lead to the formation of microcracks. It is much more problematic in high-strength concrete due to its
low water-to-binder ratio. To prevent damage, the concrete must be internally cured by introducing
additional water in the form of internal reservoirs. In this thesis, we presented superabsorbent polymers,
described their characteristics, and investigated their effectiveness as internal water reservoirs. An
experimental study was conducted in which pre-soaked superabsorbent polymer was added to the
concrete mix. Autogenous shrinkage was measured using measuring devices, and the results were
compared with a control concrete mix in the first 24 hours and after three, seven, and twelve days
following casting. We found that the inclusion of superabsorbent polymer in high-strength concrete has
a favorable effect on reducing the magnitude of early autogenous shrinkage.
