  2. Scientist makes groundbreaking discovery while studying ancient Roman technique for concrete: 'We have a huge potential'

    "Concrete has a massive carbon footprint. One researcher from the University of Auckland is working to reduce it by studying ancient #Roman techniques. Using natural volcanic materials and industrial byproducts, he's incorporating #pumice and #seashells to create an #EcoFriendly, traditional alternative.

    "At the Structures Testing Laboratory in Newmarket, New Zealand, Enrique Del Rey Castillo blends volcanic ash and kaimoana shells as replacements in the cement-making process, leveraging their #SelfHealing properties, which can repair cracks over time through natural chemical reactions.

    "This initiative is crucial, as concrete is one of the world's most polluting materials, with global cement production accounting for 8% of total carbon emissions, contributing to rising global temperatures and increasing health risks.

    "Del Rey Castillo has spent years testing how local materials can serve as sustainable alternatives. After focusing on conventional substitutes such as fly ash, he shifted to natural materials available nearby.

    " 'I realised we have a huge potential in New Zealand with the use of natural #volcanic materials and #byproducts of primary industries,' Del Rey Castillo said.

    "Concrete is essential for constructing bridges, roads, dams, and buildings, but its production releases over 4 billion tons of carbon dioxide annually. Calcining cement-primary materials at 1,500 degrees Celsius in a kiln emits large amounts of carbon dioxide and produces chemical reactions. Each pound of concrete releases 0.93 pounds of carbon dioxide.

    "Pumice, however, doesn't require the energy-intensive calcining process; it just needs to be dried at 100 degrees Celsius to remove moisture before being ground into a fine powder. 'The carbon footprint is about 8-10% of the carbon footprint of cement,' Del Rey Castillo explained."

    "The ancient Romans might have taught us a thing or two about manufacturing #sustainable concrete that lasts for thousands of years.

    "A new study has rigorously analyzed the raw materials and energy demands of their ancient recipe, revealing some useful ways to improve modern cement.

    "Surprisingly, researchers found that producing Roman mortar and concrete requires more water and more greenhouse gas emissions than #PortlandCement – the most common type of cement used in concrete today.

    "But while the initial energy costs may be steeper, Roman concrete formulations could ultimately prove more sustainable in the long run. That's because they may not need to be replaced or repaired as often."

    (1kg cement = 1kg CO2, our concrete lasts max. 50-100 years. That is a massive problem. We could use some of the Roman's self healing concrete lasting 2000 years.) (But of course, the profits...🙄 )

  9. Researchers have uncovered the secret behind the durability of ancient Roman concrete: a 'hot mixing' process using quicklime and volcanic ash. This technique resulted in lime clasts that endowed the concrete with self-healing properties, enabling structures like the Pantheon to stand strong for millennia.

  10. Interesting article about Roman #concrete and why it lasts so long. 2000 years. It was never reinforced but it was self-healing. Cracks would fix themselves. Reinforced concrete used these days only lasts 50 years. All our infrastructure needs to be redone because they used shitty building methods.

  11. So, I may be a "doomsayer" (I consider myself a realist), but I'm always trying to see if there's a solution to getting us out of the mess we're in. Perhaps I would describe myself as an optimistic pessimist. Anyhow, based on my recent research, here are some of the solutions I think we (humanity) should pursue collectively...

    1. Plug up the #MethaneLeaks! Seriously! That's a big part of the problem!

    2. Make the price of #meat expensive! I remember when having meat was considered a special occasion -- not a daily occurrence.

    3. Make things out of #RomanConcrete. Now that we've cracked the recipe, there's no excuse not to use it! Especially with rising sea levels (Roman concrete holds up better when exposed to water).

    4. Manufacture stuff that lasts! No more #PlannedObsolescence -- items that can't be upgraded and/or repaired by a skilled user or a local repair shop!

    5. Grow food locally! Turn empty #office spaces into #IndoorUrbanFarms (and #housing).

    6. Utilize new (and ancient) technologies to the max! #SolarPrisms, reflective white paint, building new structures with #skywells, #geothermal and other ways to cool/heat spaces without using #FossilFuels!

    That's just a few off the top of my head. I think a lot of the solutions are right in front of us -- but #greed and #Oligarchy are keeping them from being implemented!
