Abstract
A more economical and light-color cellular concrete is provided by the replacement of Portland cement with ground glass powder in a cellular lightweight concrete mixture and the resulting method to make cellular concrete products. The use of ground glass also increases the stability of the cellular lightweight concrete mixture during the foaming or aeration process. The products are suitable for use in structural applications, insulation, and as a lightweight aggregate.
