< div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> This specification covers dry-cast concrete ballast blocks that are primarily used for ballast of rooftop equipment. These units are machine-made from hydraulic cement, water, and suitable mineral aggregates with or without the inclusion of other materials.
< span class=" note cdone" style=" text-transform: uppercase " > Note 1:< / span> < span class=" note cdone" > The design of concrete ballast block systems for resisting wind uplift is beyond the scope of this specification.
