Technical Innovation of the Year – Projects winner
Awarded for the most innovative pump project, installation or service introduced onto the market within the last 24 months.
AODD Pump used in Foam Concrete Application Triark Pumps
By using an AODD pump at its heart, Triark developed a pneumatic ‘foam generator’ that was able to produce the same sort of foam that Celcon use in the factory production of its building blocks, but in a more liquid form to enable onsite mixing and pouring of lightweight foamed concrete to fill landfill sink holes. Attached to the side of the cement mixer, allowing use of the on-board compressor and water tanks, appropriate volumes of water and foaming agent are drawn separately into the integral AODD Pump, which mixes them in the correct ratio to produce the pre-foaming solution.
This pre-foaming solution is then forced at high pressure through a lance, to produce foam which has a volume 20-25 times that of the pre-foamed solution. The foam is then mixed into the mortar slurry to make the lightweight foamed concrete, delivering significant weight and cost savings over traditional concrete pours.
