concrete repair method as microcrystalline growth reacted fiber
The present invention relates to a new crack reduction mortar capable of improving physical performance by reducing cracks on the cross-sectional restoration surface and filling micro pores with hydration products. More particularly, the present invention relates to a preferable manufacturing method of microcrystal reaction-growth type reactive fiber, and a repair mortar and concrete cross-section repair method that preferably uses the same. According to the present invention, the microcrystal reaction-growth type reactive fiber is manufactured by mixing 11 to 16 parts by weight of micro crystallized cellulose acetate with 100 parts by weight of PVA solution and stirring to have a length of 1 to 3 mm. The microcrystal reaction-growth type reactive fiber prepared in such way can be applied as a cross-sectional repair method to concrete structures by mixing mortar to account for 0.03 to 0.40 parts by weight per 100 parts by weight of mortar and then performing repair work on the removal of deteriorated areas of the concrete structure.
본 발명은 단면복구면의 균열저감과 수화생성물에 의한 미세기공 충전을 통한 물리성능 향상이 가능한 새로운 균열저감 모르타르에 관한 것으로서, 미세결정반응 성장형 반응섬유의 바람직한 제조방법, 그리고 이를 바람직하게 이용한 보수모르타르 및 콘크리트 단면 보수공법에 관한 것이다. 본 발명에 따른 미세결정반응 성장형 반응섬유는 PVA용액 100중량 대비 미세결정화 셀룰로오스아세테이트를 11~16중량부 혼입 교반하여 1~3mm의 길이를 갖도록 제조하는 것을 특징으로 한다. 이렇게 제조한 미세결정반응 성장형 반응섬유는 모르타르 100중량부에 0.03~0.40중량부를 차지하도록 모르타르를 배합한 후 콘크리트구조물의 열화부위 제거 부분에 보수 시공하는 방법을 통해 콘크리트 구조물 단면보수공법으로 적용할 수 있다.
