ELASTIC INJECTION COMPOSITION FOR REPAIRING EXPANTION JOINT OF CONCRETE STRUCTURE AND REPAIRING METHOD OF EXPANTION JOINT OF CONCRETE STRUCTURE THEREWITH
The present invention relates to an elastic injection material composition for repairing an expansion joint of a concrete structure and a method of repairing the expansion joint of the concrete structure using the elastic injection material composition, the elastic injection material composition comprising 3 to 90 wt% of a rapid hardening elastic binder and 10 to 97 wt% of a performance improving filler, the performance improving filler including 10 to 80 wt% of siliceous silica, 5 to 30 wt% of calcium carbonate, 5 to 30 wt% of bauxite, 1 to 25 wt% of silicon nitride, 0.1 to 20 wt% of aluminum oxide, 0.1 to 20 wt% of aluminum nitride, 0.1 to 20 wt% of sepiolite, 0.01 to 15 wt% of chromate, and 0.01 to 15 wt% of zinc oxide. The elastic injection material composition according to the present invention not only can prevent a minute change in the length of the concrete structure according to changes in surrounding temperature by having excellent elasticity, adhesive force, flexural strength, tensile strength, durability, flexural toughness, waterproof property and surface hardness, thereby enabling the length of the concrete structure to be elongated or contracted by heat, but also can minimize damage to an expansion joint by preventing infiltration of rainwater or foreign materials through an integrated movement with the concrete structure. Further, the elastic injection material composition according to the present invention enables economical construction to be achieved by using the rapid hardening elastic binder to shorten a construction time, and minimizing an unnecessary construction process such that construction costs can be reduced.
본 발명은, 속경형 탄성 결합재 3~90중량% 및 성능개선 충전재 10~97중량%를 포함하며, 상기 성능개선 충전재는 실리카질 규사 10~80중량%, 탄산칼슘 5∼30중량%, 보크사이트 5∼30중량%, 질화 규소 1∼25중량%, 산화알루미늄 0.1∼20중량%, 질화 알루미늄 0.1∼20중량%, 세피올라이트 0.1∼20중량%, 크로뮴산염 0.01~15중량% 및 징크옥사이드 0.01∼15중량%를 포함하는 것을 특징으로 하는 콘크리트 구조물 신축이음부 보수용 탄성 주입재 조성물 및 이를 이용한 콘크리트 구조물 신축이음부 보수방법에 관한 것이다. 본 발명에 의하면, 탄성, 접착력, 휨강도, 인장강도 및 내구성, 휨인성, 방수 및 표면경도가 우수하여 콘크리트 구조물이 열에 의해 길이가 신장, 수축되어 주위 기온의 변화에 따라 미세하게 그 길이가 변화되는 것을 방지할 수 있고, 콘크리트 구조물과의 일체 거동을 통하여 빗물이나 이물질의 침투를 방지하여 신축이음부 파손발생을 최소화할 수 있다. 또한, 속경형 탄성 결합재를 사용함으로써 시공기간을 단축하고 불필요한 시공공정을 최소화하여 공사비를 절감할 수 있는 경제적인 시공이 가능하다.
