Reviews often refer to this as the "boil test" because it uses boiling water to drive air out of the concrete's pores. It is highly valued for its ability to rank concrete durability by measuring the volume of permeable voids (VPV).

Specimens should be representative of the concrete mass being evaluated. Typically, drilled cores or cast cylinders are used.

The properties are calculated using the masses determined in the procedure.

for at least 48 hours. This continues until mass increases by less than 0.5% between daily weighings.
