What is it about?
The paper concerns destructive and non-destructive (NDT) evaluation of the effect of the addition of superabsorbent polymer (SAP) used as a carrier of mixing water and a means of internal curing on the durability of concrete.The analysis of test results showed that the method of introducing the mixing water into the concrete mix in the form of preabsorbed superabsorbent polymer, although it changed the concrete mix consistency, did not significantly affect the concrete ability to resist carbonation. Meanwhile, after 3 years, the densification of the microstructure of concrete with SAP has been observed.

Why is it important?
Verification of the effectiveness of a new method of internal concrete curing.
Perspectives
There is not much experimental data on the durability of concrete with SAP. There is a lot of work to do and many problems to investigate in this area of resarch.
