REINFORCING METAL FIBER AND PVA FIBER CONCRETE AND MANUFACTUARING METHOD THEREOF, REPAIR PROCESS OF PAVEMENT USING THE SAME THING
The present invention relates to a steel fiber and poly vinyl alcohol (PVA) fiber reinforced concrete composition, a preparation method thereof, and a repair method of a concrete structure by using the same, which comprises: 9-20 wt% of cement; 5-10 wt% of water; 30-35 wt% of fine aggregate; 30-44.6 wt% of coarse aggregate; 7-17 wt% of recycled coarse aggregate; 4-7 wt% of fine powder of blast furnace slag, wherein 0.1-1.5 parts by volume of a PVA fiber and 0.3-1.7 parts by volume of a steel fiber are further comprised, based on 100 parts by volume. According to the present invention, weight is reduced, tensile stress and cracking occurring in contraction caused by the drying or freezing of concrete are inhibited, strength and toughness are increased, and resistance to impact, abrasion and fatigue, and durability are enhanced to improve stability and durability of a structure. Furthermore, application thereof is expanded to improve usability.
본 발명은 시멘트 9~20 중량%; 물 5~10 중량%; 잔골재 30~35 중량%; 굵은골재 30~44.6 중량%; 순환굵은골재 7~17 중량%; 고로슬래그 미분말 4~7 중량%; 전체 체적부가 100일 경우, PVA(Poly Vinyl Alcohol)섬유 0.1~0.5 체적부; 강섬유 0.3~1.7 체적부;를 더 포함하는 것을 특징으로 하는 강섬유 및 PVA섬유 보강 콘크리트 조성물 및 그 제조방법과 이를 이용한 콘크리트 구조물의 보수공법을 제시함으로써, 무게를 경량화함과 더불어, 콘크리트의 건조 또는 동결에 의해 수축 시 발생되는 인장응력 및 균열을 억제하며, 강성을 증가시키고, 인성의 증가와 충격, 마모, 피로에 대한 저항성과 내구성을 증대시켜 구조물의 안정성 및 내구성을 향상시킴과 더불어, 적용범위를 확대하여 사용성을 향상시키도록 한다.
