#For better concrete, do did as Romans University of California Berkeley rightoriginal Studyposted by Sarah Yang-Berkeley on June 5 2013uc BERKELEY (US)# Ancient Roman structures that have withstood the elements for more than 2000 years

The discovery could help improve the durability of modern concrete which within 50 years often shows signs of degradation particularly in ocean environments.

The manufacturing of Roman concrete also leaves a smaller carbon footprint than does its modern counterpart.

The process for creating Portland cement a key ingredient in modern concrete requires fossil fuels to burn calcium carbonate (limestone) and clays at about 1450 degrees Celsius (2642 degrees Fahrenheit.

The production of lime for Roman concrete is much cleaner requiring temperatures that are two-thirds of that required for making Portland cement.#

#Roman concrete has remained coherent and well-consolidated for 2000 years in aggressive maritime environments#says Marie Jackson a research engineer in civil and environmental engineering at University of California Berkeley.#

and colleagues characterized samples of Roman concrete taken from a breakwater in Pozzuoli Bay near Naples Italy.#

Of particular interest to researchers is how Roman#s underwater concrete endured the unforgiving saltwater environment.

The recipe for Roman concrete was described around 30 BC by Marcus Vitruvius Pollio an engineer for Octavian who became Emperor Augustus. The not-so-secret ingredient is volcanic ash

which Romans combined with lime to form mortar. They packed this mortar and rock chunks into wooden molds immersed in seawater.

Rather than battle the marine elements Romans harnessed saltwater and made it an integral part of the concrete.

Also key was a very rare hydrothermal mineral called aluminum tobermorite (Al-tobermorite) that formed in the concrete.#

#Our study provided the first experimental determination of the mechanical properties of the mineral#Jackson says.

Use of Roman concrete decreased because#as the Roman empire declined and shipping declined the need for the seawater concrete declined#Jackson says.#

#Earth-friendly alternativewhile Roman concrete is durable it#s unlikely to replace modern concrete because it is not ideal for construction where faster hardening is needed.

But the researchers are now finding ways to apply their discoveries about Roman concrete to the development of more earth-friendly and durable modern concrete.

#Biologist creates'self-healing'concrete No matter how carefully it is mixed or reinforced, all concrete eventually cracks,

"The problem with cracks in concrete is leakage, "explains professor Henk Jonkers, of Delft University of Technology, in The netherlands."

Secondly, if this water gets to the steel reinforcements--in concrete we have all these steel rebars

"But Jonkers has come up with an entirely new way of giving concrete a longer life."

"We have invented bioconcrete--that's concrete that heals itself using bacteria, "he says. The bioconcrete is mixed just like regular concrete,

but with an extra ingredient--the"healing agent.""It remains intact during mixing, only dissolving and becoming active

"You need bacteria that can survive the harsh environment of concrete, "says Jonkers.""It's a rocklike, stonelike material, very dry."

"The next challenge was not only to have the bacteria active in concrete, but also to make them produce repair material for the concrete--and that is limestone,

"Jonkers explains. In order to produce limestone the bacilli need a food source. Sugar was one option, but adding sugar to the mix would create soft, weak, concrete.

When cracks eventually begin to form in the concrete, water enters and open the capsules.

Now Jonkers hopes his concrete could be the start of a new age of biological buildings."
