CEMENT BINDER COMPOSITION CONTAINING CATIONIC SUPERABSORBENT POLYMER HAVING RAPID CRACK SELF-SEALING EFFECT AND MANUFACTURING METHOD OF CATIONIC SUPERABSORBENT POLYMER

摘要

The present invention relates to a cement binder composition for improving self-healing, including a cationic superabsorbent polymer having a rapid crack self-sealing property, and a method for preparing a cationic superabsorbent polymer. The present invention can reduce the compressive strength loss by minimizing the pore size generated by the initial expansion by swelling is suppressed in the environmental conditions in the cement system immediately after pouring, and at the same time, excellent self when the pH neutral or acidic solution penetrates into the crack By producing a self-sealing effect and ultimately enhancing the ability to crack self-healing, a cationic high-absorption polymer is prepared, and the self-healing ability and compressive strength improvement effect of the cement binder composition including the same are improved. Can provide.
