A more economical, stable, non-shrinking cellular concrete is provided by the addition of cementitious or non-cementitious fines to a cellular concrete mix. The improved cellular concrete is attained by reducing the amount of cement and replacing it with an equal amount of cementitious or non-cementitious fines. The partial replacement of the more expensive cement for the less expensive fines results in a more economical choice of cellular concrete suitable for use in structural applications, for insulation purposes, and for use in producing lightweight aggregate.
