Effect of superabsorbent polymers on hydration heat evolution of cementitious materials
Original language description
Modification of concrete represents a substantial issue in the field of materials science. In this sense, an understanding of the interaction between various compounds poses a crucial issue that needs to be resolved and described in detail. The utilization of superabsorbent polymer (SAP) as an internal curing agent for the mitigation of autogenous shrinkage may result in modifications in the thermodynamic behavior of Portland cement hydration. While the mechanism of various types of SAPs on mechanical properties has been reported considering several aspects, the application of SAPs in cementitious materials is lacking, and the proper description and influence on chemical nature and physical properties are not available. In this paper, the effect of three different SAPs on early hydration evolution is studied. Obtained characteristics by meaning hydration, heat evolution, initial reaction, and setting period are linked together with the functional parameters of the designed concrete mortar mixtures in a hardened state to provide important information for the building practice.
