Concrete Pipe

Using more sludge and less slag in their recipe, researchers were able to create a material that's stronger than even today's enhanced cements and highly resistant to corrosion by acid. It could solve a serious problem facing sewer pipes worldwide.

Concrete sewage pipes lead a hard life, constantly being exposed to corrosive acid produced by bacteria in wastewater. A new additive could allow such concrete to self-heal – and it would do so using water treatment sludge.

Sleeping in a culvert generally means you've fallen on hard times, but that's not the case with this unique project by Nendo. The minimalist dwelling is built using the precast concrete box culverts usually used to construct waterways and tunnels.

Industrial piping has a hard life, as it's constantly exposed to liquids that can damage its inner surface over time. A new polymer coating could help protect such pipes, while removing toxic metals from the liquids as it does so.

The OPod Tube House, by James Law Cybertecture, is a micro house made from concrete water piping that measures just 2.5 m (8.2 ft) in diameter. Its snug interior features an apartment-style layout suitable for one or two people.

Local architectural studio Techne was asked to re-think the facade and concept design of the Prahran Hotel in Melbourne.
