CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

General FAQ Geofill Cellular Concrete Foam Technology

By definition "lightweight" concrete is a concrete made with aggregates that are lighter than typical stone aggregates. Typically, lightweight concrete has a density 120 lb. / cu.ft. In contrast, Geofill cellular concrete uses the internal air cell structure instead of an aggregate and exhibits densities from 20 to 90 lb. / cu. ft.
