Artificial intelligence innovates a new method for preparing concrete in MIT research
Revised Article
Ready to revamp concrete and save the planet, one mix at a time? A dynamic team at the Olivetti Group and MIT Concrete Sustainability Hub (CSHub) is diving headfirst into the tricky conundrum of minimizing cement usage in our beloved, yet polluting, construction staple.
The question on everyone's minds has been, "How can we cut cement and emissions while keeping our wallets full?" For decades, alternative materials like fly ash and slag have been in the mix, but the demand is soaring, and supplies are dwindling as the industry looks to slash its carbon footprint.
In the face of this mountain of data and options, the team stumbled upon an unexpected solution-artificial intelligence. With big language models powering their daily chats, they built a machine-learning model that weeded out ineffective materials based on their physical and chemical properties.
So, what makes the perfect alternative to cement? Hydraulic reactivity and pozzolanicity, according to Soroush Mahjoubi. If the substitute doesn't react like cement when wet or interact with calcium hydroxide, hardening and strengthening over time, it ain't gonna fly.
With the AI-driven framework, the team scanned through scientific literature and a gargantuan 1 million rock samples, classifying potential materials into 19 distinct categories, from biomass to mining byproducts to demolished construction materials. To their delight, they found that suitable substitutes were readily available globally and could be easily incorporated into concrete mixes by mere grinding. Boom! Emission and cost savings galore!
Out of all the possibilities, ceramics have piqued Mahjoubi's interest. Think old tiles, bricks, and pottery — classic, functional, and possessing stellar reactivity. Intriguingly, Roman engineers were onto something back in the day when they added ceramics to waterproof their structures. It seems that grandpa had the green thumb after all!
This circular economy furniture swap could be the key to building a more sustainable future. By repurposing materials destined for landfill as the base for our buildings and infrastructure, we can divert waste and contribute to a greener planet.
As the research progresses, Mahjoubi, along with Professor Elsa Olivetti and Randolph Kirchain, are upgrading the AI framework and experimentally testing the top candidates. "This swift research journey is made possible through the latest developments in large language models," notes Olivetti, an MIT Climate Project mission director, CSHub PI, and Olivetti Group leader.
"Concrete is the unsung hero of our built world," says Kirchain. "By harnessing the power of data science and AI, we aim to revolutionize the way we build sustainably, with minimal impact on structural integrity, safety, or durability."
Up Next:- Got a hardheaded ceramic lying around? It may be your ticket to a greener future!- Keep an eye out for more promising materials like low-grade clay, calcium silicate rocks, LC3 cement, and geopolymers from construction waste.
Plunge into the exciting world of alternative concrete materials, and let's build a greener tomorrow!
FYI:- Ceramics, that even include old tiles, bricks, and pottery, could significantly reduce the amount of cement used in concrete production, ultimately resulting in decreased carbon emissions and cost savings.- Other promising materials for reducing cement usage include low-grade clay, calcium silicate rocks, LC3 cement, and geopolymers from construction waste.
