A Study of Behavior of Reinforcement Steel Embedded in Corrugated Duct

Abstract

This research aims to study the behavior and failure characteristics of precast concrete structure joints using reinforcing steel embedded in galvanized corrugated duct. The fours mixing ratio between non-shrink grout and Portland Cement Type 1 will be used as grouting material to fill in corrugated duct are 1:0, 1:1, 1:2 and 1:3. The tensile strength and behavior of this type of joint due to the joint strength that developed between reinforcing steel and grouting material in corrugated duct will be investigated. From the test results, it was found that the behavior of reinforcing steel working in corrugated steel pipes together with cementitious materials in the ratio of 1:0, 1:1 and 1:2 can support the tensile strength until failure at the steel reinforcement. In terms of behavior of reinforcing steel working in corrugated steel pipe with binder in ratio 1:3 may not be clear. Due to the tensile behavior of the reinforcing steel of 1 of the 3 test specimens, it was unable to support the tensile strength until failure occurred at the reinforcing steel.
