Concrete’s modification with a superabsorbent polymer (in the form of granules absorbing a significant amount of mixing water), is a method of internal curing leading to a significant reduction in concrete shrinkage. The impact of such modification on other properties of concrete is the subject of many studies presented in the latest world literature while there are few reports on the course of carbonation of such modified concrete. The article present the results of carbonation tests under accelerated conditions and the mechanical properties of high-performance concretes modified with the addition of SAP in various variants.
