One person can produce 100 to 270 cubic feet of foamed concrete per hour on site with the Aercrete 625 volumetric mixer. A remote control allows the operator at the end of a 70-foot delivery hose to adjust the machine’s production rate or shut the machine down. The Aercrete 625 can produce self-leveling foamed concrete with densities of half that of conventional concrete using cement, water, sand and a foaming agent such as Aercell A-7. It can also mix and place plaster, stucco and grout. The self-contained, diesel-powered mixer weighs 7,716 pounds and can be towed behind an SUV or pickup truck. The Aercrete 625 retails for about $275,000.
