Mortar composition for repairing and reinforcing underwater concrete structures and method of repairing and reinforcing underwater concrete structures using the same

摘要

The present invention relates to a mortar composition for repairing and reinforcing underwater concrete structures, and a method of repairing and reinforcing underwater concrete structures using the same. More specifically, provided is a method of repairing and reinforcing underwater concrete structures using a mortar composition of the present invention, which improves the adhesion strength to concrete structures to maintain the maintenance and reinforcing effect for a long time when repairing and reinforcing the cross section of the underwater concrete structures; allows users to stably complete the underwater repairing and reinforcing construction in a short time, thereby exhibiting economic feasibility; provides an excellent neutralization prevention effect of concrete; and especially, strengthens the water tightness to minimize the influence of external environment to the underwater concrete structures. Additionally, in the mortar composition, a binder and a control agent are mixed in an optimum ratio to control the solidification speed and exhibit fast hardening properties.
