摘要

Manufacturing of galvanized Si containing steel with conventional Hot Dip Galvanizing line operation are usually considered as more difficult. This is because Si is selectively oxidized at the steel surface during recrystallization annealing and formed Si oxide repels molten Zn. To improve such a poor Zn wettability, oxidation/reduction method is proposed as one of the solution. In this technique, pre-oxidation behavior is one of key factor to control. Therefore, influence of carbon content on the oxidation behavior of Si containing steel was investigated at 700 °C in N_2-0.1vol%O_2 atmosphere. Based on SEM observation, the formation of Fe oxide on the surface was accelerated with higher carbon content and lowering P_(O2) model by decarburization at the interface between Fe oxides and bulk was discussed based on GDS, EDX and TEM analysis.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
