With rather humble origins as a soft, red, mineral-laden rock called bauxite, highly valuable aluminum ore contains boehmite, diaspore and gibbsite as well as clay, iron hydroxides and free silica. On an annual basis, more than 130 million tons of bauxite is extracted globally, and current estimates suggest that we have enough reserves to carry us through the next 400 years .

When aluminum is in contact with fresh concrete, a surface reaction occurs between the aluminum and the alkaline constituents of the concrete resulting in a slight superficial attack on the metal. This attack occurs over the first four or five days and then subsides. In this four to five day period, aluminum will be etched to a depth of one-half to 1 mil. The attack, however, does not affect

Bonding aluminum to concrete is essential for many home repair projects. The different chemical makeup in both materials makes it difficult to bond one to the other without an appropriate adhesive. Failing to use the right glue can result in the melting or freezing of the adhesive -- due to expanding or shrinking of aluminum, for example -- and detaching of the bond. The trick to securing a
