Concrete = 7% Global CO2 Emissions, Cure = E-Crete from Zeobond? (Video)

E-Crete from the Zeobond company in Melbourne, Australia a is pourable green building material designed with the intention of reducing GHG emissions associated with the use of conventional cement: every ton produced also produces about a ton of CO2. Two and a half billion tons of cement are made every year to equal 7 percent of total global carbon dioxide emissions. We clear the air on concrete some more below the fold...Carbon Dioxide Emissions from Global Production of Concrete

Over the next decade the, global production of cement and the resulting emissions are expected to double. E-crete is made from recycled ash and slag which are waste by-products from iron and steel manufacturing. The making of E-crete does not require the burning of limestone which gives off large amounts of CO2. It has a high fire-resistance of up to 1000 degrees centigrade and is also highly acid resistant. Its inventor also claims that it sticks to steel in a chemical way for a stronger bond.

Barriers to the adoption of green building materials

Given the track-record and reliability of conventional concrete, getting new environmentally-friendly materials used for building projects can be a challenge. Building anything is generally costly and of course safety and potential liability can make those calling the shots not so itchy to pull the trigger on unfamiliar materials. Given that, about a year ago Zeobond began to roll-out E-Crete to customers such as individuals and local councils, who would use it in small, non-safety-critical projects, such as building patios and walls on motorways that block sound.

Also, unforch, E-Crete costs about ten percent more than conventional concrete. For now...

Clearing up confusion about the name E-Crete

Australian Zeobond's cement-substitute product "E-Crete" shares the name with U.S.-based company "E-Crete," the makers of structural, aerated concrete block known as AAC.
