Concrete. The main environmental impact associated with concrete stems from its cement. Although cement makes up only 10 percent of the concrete mix, it is responsible for over 80 to 90 percent of concrete’s embodied carbon. Cement production involves heating a mixture of limestone, silica, alumina and gypsum to 1,400-2,000 degrees Celsius.

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
