dc.description.abstract본 연구에서는 플라이 애시(FA), 보통 실리카퓸(SF)과 지르코늄 실라카퓸(Zr)을 사용한 PSC 그라우트의 재료특성을 평가하였다.실험결과, FA와 Zr을 사용한 그라우트 배합들은 적은 감수제 혼입량에서도 우수한 유동성을 나타냈으나, 계획된 시간에 측정된 블리딩 및 체적변화량은 증가하였다. 압축강도는 모든 그라우트 배합들에서 재령 7, 28일에 우수한 강도 발현을 나타났고, 3성분계 그라우트 배합들은 2성분계 그라우트보다 우수한 거동을 보였다. 또한 3성분계 그라우트 배합들을 수축저감제(SRA)와 팽창재(EA)를 병용하여 자기수축 특성을 평가한 결과, SRA와 EA를 사용함으로써 자기수축을 47~80% 저감하였으며, SF을 사용한 그라우트 배합에서 효과적인 수축저감 특성을 나타냈다.This experimental study investigates material properties of prestressed concrete (PSC) grout depend on the combination of fly ash (FA), silica fume (SF) and zirconia silica fume (Zr). Based on the test results, when FA and Zr were included in grout mixtures, the fluidity, bleeding and volume change increased with less superplasticizer. The compressive strength of all grout mixtures was quite high at the age of 7 and 28 days, and the ternary mixtures had the excellent development of strength than binary mixtures.Furthermore, autogenous shrinkage properties of ternary grout combining shrinkage reducing agent (SRA) and expansive additive (EA) was evaluated. The 47~80% autogenous shrinkage was reduced by using SRA and EA. In addition, the effectiveness of using SRA and EA was higher for the grout mixture with SF than that with Zr.en_US
