This article provides information on the mechanism of plastic shrinkage in the early stages of hardening, its action on the cement stone and ways to reduce it. It is found that an effective way of reducing plastic shrinkage is the use of superabsorbent polymers as a moisture storage and its subsequent return. Definitely the impact of superabsorbent polymers on technological and physico-mechanical properties of the cement stone with the size of grains of the studied additives. The grain size of the superabsorbent supplements is an important parameter that has a significant impact, both on the physical and mechanical properties as well as on plastic shrinkage of cement stone.
plastic shrinkage, hydration of cement, capillary pressure, superabsorbent polymers.
