Concrete despite many performed studies still requires further research on material optimization towards its improvements. On this account the superabsorbent polymers can be viewed as very promising materials with a positive influence on various properties of cementitious materials. The beneficial effect of SAPs on mitigation of autogenous shrinkage or rapid cracks self-healing. However, the absorption capability of SAPs also poses a risk for the formation of dense structure and loss in material durability. The performed study contemplating the influence of two grades of SAP admixtures on mechanical parameters of designed concrete. Obtained results revealed an adverse effect of SAPs on compressive strength. This finding can be assigned to a rapid swelling capability of SAPs, thus a formation of voids in material structure and a significant increase in the total open porosity. Incorporation of about 1.5 wt.% of SAP admixture decreased compressive strength about almost 50% compared to the reference sample.
