LONG TERM DRYING AND WETTING BEHAVIOR OF CONCRETE WHOSE CRACKS WERE REPAIRED WITH SILANE TYPE WATER REPELLENT

Abstract

 This study focuses on the effect of repairing crack with silane type water repellent on water absorption of concrete. Experimental results showed that the silane type water repellent applied to the cracked concrete reduced of water absorption. By examination using the numerical simulation of moisture transfer of concrete that the effect of repairing crack with silane type water repellent is inhibit water absorption and reduce the moisture transfer at impregnated area.
