Abstract
The internally cured material known as superabsorbent polymer (SAP) is an important innovation in concrete engineering technology. This paper investigates the effect of adding a polymer with superabsorbent capabilities on the physical and mechanical performance of concrete. The microstructure of the new hybrid concrete was also studied, and the influence of the polymer particle size and volume on the mechanical durability was evaluated. The mechanical properties of the new hybrid concrete, such as compressive strength, flexural strength, elastic modulus, and splitting tensile strength, were measured through laboratory experiments. The microstructure characteristics of the concrete were also investigated by scanning electron microscopy (SEM). The results show that shrinkage was reduced, while the volume stability of the concrete improved. Moreover, we found that cracking was reduced, while issues such as chloride penetration and freeze-thaw resistance were also improved. In addition, the SAP could effectively improve the microstructure of the concrete and refine the pore structure, as seen in the microscopic test. This paper helps to promote the development of internally cured material and improve technology for the prevention of concrete construction cracks.

The compressive strength of concrete at two watercement ratios is shown in Figure 3, from which we found that the compressive strength was directly proportional to the age and water-cement ratio, which was lower than that of the control group
Summary
It is essential for sustainable development in concrete engineering to develop a resource-saving strategy. Improving the construction quality and working performance has been the core of the development of concrete engineering construction [1]. Internally cured technology for concrete is gradually being developed [3,4]. SAP, an internally cured material, is a macromolecular substance with a super water absorption capacity and strong water retention ability, which can effectively improve volume stability of the concrete, such as micro-cracks, autogenous shrinkage, and the drying shrinkage of concrete. The volume stability and durability of the concrete are improved due to its strong water retention capacity and chemical hydrophilic group structure [5,6,7]
