Quantities may be varied or alternate designs submitted to adapt
mix to meet density and strength requirements or to adapt to specific
site conditions.

Requires the use of suitable lightweight aggregate or air-entraining
admixture. Provide a mix design that achieves the specified strength
and density requirements.

****
|
As appropriate, depending on whether lightweight aggregate or
air-entraining admixture is used to obtain lightweight properties.
