Entainment of a small amount of air in the cement concrete has been found to improve considerably the durability of concrete. The recommended limits specified for the air content are between 3% and 6.5%. Small percentages may result in deterioration taking place more quickly, and larger percentages may reduce the strength without any addition in the durability of concrete.

It consists of a pressure-tight flanged cylindrical measuring bowl, fitted with a removable flanged and a conical cover assembly with a seal in between. The conical cover has an air valve and a pet cock for bleeding-off the water. A cylindrical stand pipe, which is graduated in percent air content, is fixed on the conical cover assembly. Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, trowel and tamping bar.
