Abstract
The aim of this review paper is to summarize available reports, papers, theses, dissertations and conference papers dealing with the performance of aluminum-concrete composite columns. Hollow aluminum sections filled with concrete have been used as composite columns due to their corrosion resistance, easy production, appearance and lightweight. Many researches were performed in the area of concrete-filled hollow sections (tubes). However, there are few researches have been performed on concrete-filled aluminum tubes. In this review, different available published papers are summarized to view the type of the studied aluminum-concrete columns and the main studied parameters that affecting the behavior of these composite columns. More than (190) specimens are collected and showed in this review.
Highlights
Columns composed of more than one material are usually called composite columns
Conventional reinforced concrete columns may be referred as composite columns since they composed of steel and concrete, the term 'composite columns' is usually used to refer applications such as sections filled with or encased in concrete as shown in Fig. (1)

Summary
Columns composed of more than one material are usually called composite columns. In these columns, different materials may work together to resist strains and stresses induced by external applied loads. Conventional reinforced concrete columns may be referred as composite columns since they composed of steel and concrete, the term 'composite columns' is usually used to refer applications such as sections filled with or encased in concrete as shown in Fig. Hollow aluminum sections filled with concrete have been used as composite columns due to their corrosion resistance, easy production, appearance and lightweight. Filling hollow sections with concrete will increase the capacity of these sections. Thereby the capacity and stiffness of aluminum tubes will be increased by the concrete filling.
