Study on Adding Super Absorbent Polymer to Improve the Frost Resistance of Concrete

Internal curing was especially beneficial to improve concrete performance. The super absorbent polymer and fly ash were used in the concrete and the frost resistance of concrete was studied. The result indicated that the super absorbent polymer changed the pore structure, increased the quantity of the pore, decreased the strength loss 5-10% after 250 freeze-thaw cycles and improved the frost resistance of concrete.
