In this study, pull-out tests were performed for evaluating tensile behavior of chemical anchors. Diameter and embedment length were considered as test variables. During the test, uplift load and vertical displacement of chemical anchors were measured. Maximum uplift load of 16kN was measured in chemical anchor having 21mm diameter and 300mm embedment length.

This experimental study investigates the influence on the tensile behavior of strain-hardening cement composite (SHCC) with HR and SWP Shrinkage Reducing Admixture (SRA). SRA can also improve the tensile strength and multiple cracks of SHCC material used in this study.

This research investigated the influence of adding SRA(Shrinkage reducing agent) on the direct tensile behavior of UHPFRC(Ultra high performance fiber reinforced concrete). The experimental test results revealed that the post cracking strength and strain capacity for the cement hydrated cement paste without at SRA were higher than that incorporate with 1% SRA.

This experimental study examines the test results on the flexural behavior of strain-hardening cement composite (SHCC) with two types of Shrinkage Reducing Admixture (SRA). An influence of SRA on the flexural behaviors of SHCC mixes was observed.

Mechanical performance of UHPC is known to be strongly influenced by placing method. In this study, in order to estimate variation in tensile behavior of hybrid fiber reinforced UHPC, two different placing methods were adopted in fabricating test specimens. Test results presents that placing method causes a noticeable variation in the tensile behavior

철근콘크리트 구조물에서 배근상태에 따라서는 다짐불량에 의한 재료분리 및 골재폐쇄현상이 발생하여 채움이 제대로 되지 않는 경우가 발생할 수 있다. 본 연구에서는 그 영향을 충분히 고려하지 않고 있는 재료분리에 따른 중립축이하 인장부 콘크리트가 보부재 거동에 미치는 영향 파악을 위한 실험을 수행하여, 보부재의 인장 철근영역 콘크리트의 유효성 파악을 위한 연구를 수행하였다. 실험결과 인장철근영역 콘크리트의 재료분리에 따른 거동은 부재항복강도에는 미치는 영향이 없으나, 부재 휨연성, 전단저항능력을 저하시키는 것으로 나타났다.
