Last week, C-Crete participated in the “Eastern US Low-Carbon Concrete Convening” in Boston, sponsored by the White House, the National Resources Defense Council, National Ready Mixed Concrete Association, and RMI. C-Crete founder, Rouzbeh Savary, gave a talk on C-Crete’s cement-free concrete projects, highlighting those in the Northeast, and shared the stage with other low-carbon enthusiasts including Ben Myers, Jim Carreira, Beverly Craig, Patrick Grasso and Craig Dauphinais.

Returning to Boston always brings back good memories of where C-Crete was initially started and how far we have come, from reducing the carbon footprint of Portland cement to entirely eliminating it from concrete, coinciding with its 200th anniversary of use in concrete. Currently, the volume of Portland cement-free concrete that C-Crete has poured in various projects is greater than that of any other company in the world, whether small or large.

Thanks to Andres Clarens, Frank Mruk, Anish Tilak, and others who organized this exciting event and dialogue.

We are thrilled to officially announce the development and pouring of the world’s first granite-based concrete - free from Portland cement and its CO2 emissions - at a supertall building in NYC.

Thanks to the C-Crete team for their unparalleled commitment: so far, C-Crete has introduced and poured various Cement-free Concrete (C-Crete) products based on basalt, zeolite, and now granite. Each of these products represents a world record following the 200-year reign of carbon-heavy limestone-based portland cement concrete. The reserves of each rock sit on every continent, and their deposits are on par with or exceed those of limestone.

C-Crete founder, Rouzbeh Savary, shared the following: "Regarding 270 Park Ave in Manhattan, the new global HQ of
JPMorganChase, I first became familiar with Lord Norman Foster’s aesthetically designed structures about 26 years ago. Captivated by their majesty - his Millau Viaduct was the cover of my presentations for years - I followed my passion for material design and discovery of the elementary units that hold up such magnificent structures. Now my “material design” breaks into his “building design”! immense joy… Even if it is small for now, every giant leap begins with a small step."

Many thanks to the following for helping this pivotal pour in Manhattan: Allan Paull, Max Driscoll, and Jeremy Williams at
AECOM Tishman; Fortunato Orlando at Severud Associates; Chris De Luca at Tishman Speyer; Michael Prince at JPMorganChase; Michael Zagula and Constantine Quadrozzi at
SRM Concrete; and others. History will remember you as harbingers of sustainable supertall buildings. Looking forward to the day we pump cement-free concrete to the last floor, touching the sky!

Exciting news: We paved the way for a brighter future!

Last month, we paved a section of Highway I-94 Westbound in Minnesota with Cement-free Concrete (C-Crete), which is free of Portland cement and its CO2 emissions. We captured these shots at the sunrise on the horizon of the first-ever highway paved with C-Crete. Hope paving with new low-carbon materials on this and similar highways continues, taking us sooner to net-zero carbon destination.

If you ever pass Highway I-94 Westbound in MN around Mile 198, remember two things: 1) you are driving on Cement-free Concrete (C-Crete), and 2) how excited the C-Crete team was! Not because our product was used there, but because the 200-year reign of Portland-cement concrete on infrastructure of human civilization has begun its descent.

For this project, from introduction to implementation took only about a month (including meeting MnDOT testing requirements, independent third-party verifications, approval, shipping, paving, curing, etc.).

Thanks to the Minnesota Department of Transportation, MnROAD, Holcim, Braun Intertec Corporation, Larry Sutter, and others who helped make this happen.

In August, C-Crete founder, Dr. Rouzbeh Savary, gave a presentation on Cement-free Concrete (C-Crete) in the steel city of America, Pittsburgh, PA, during the US DOE’s Annual Carbon Management meeting. Verified by independent third parties, C-Crete’s latest strength reaches more than 5000 psi in just one day and increases over time, effectively capturing a significant portion of steel’s strength while costing a fraction of steel’s cost - all without Portland cement and its CO2 emissions (see enclosed C-Crete cylinder).

Last year, when C-Crete launched the product it was reaching ~5000 psi in 28 days. We are now applying C-Crete in both precast and cast-in-place structural concrete applications.

This summer, at the National Renewable Energy Laboratory (NREL) Cement and Concrete Decarbonization annual meeting in Golden, CO, C-Crete's founder, Dr. Rouzbeh Savary, gave a technical talk on Cement-free Concrete (C-Crete) in one session and served as a panelist on the commercialization of low-carbon concrete in another. He discussed some of our past, current, and future residential, commercial, and government projects using C-Crete, along with its aesthetic features, such as various surface finishes and a suite of earthy-tone colors enabled by natural rocks.

What is shown in the pictures is a sample of a Terrazzo floor made with C-Crete. It is extremely polished, smooth, and durable, making it suitable for high-traffic areas such as airport floors, shopping malls, banks, and industrial spaces. C-Crete is already applying it to commercial floors. Compared to conventional Portland cement, C-Crete has approximately 100% lower CO2 emissions on a one-to-one basis, yet it costs the same.

Thanks to Ana Aday and other NREL staff for organizing this exciting meeting!

Recently, C-Crete was featured in this article in Scientific American. “Their hearts are in the right place. Their economic eye is in the right place,” said Dr. Jeff Bullard, a professor at Texas A&M University. “But a lot of times the construction industry is very resistant to this kind of stuff.” That is right, but C-Crete team is on a mission to change this pattern and mentality. Thanks to POLITICO and Francisco Camacho for covering this. Read more here:

This summer, the U.S. General Services Administration (GSA) announced that its Green Proving Ground (GPG) program has selected Cement-free Concrete (C-Crete), along with other sustainable technologies, for evaluation in real-world government buildings towards the goal of net-zero emission federal buildings. GSA provides centralized procurement and shared services for the federal government, managing a nationwide real estate portfolio of nearly 370 million rentable square feet. Given that more than half of the total concrete in the US is used for government applications, C-Crete is proud to be included in this GSA program, which is run in collaboration with DOE.

Recently, another pour of Cement-free Concrete (C-Crete) began for a ground-up residential house overlooking the beautiful Cle Elum Lake near Seattle, WA. The design somewhat resembles to Eichler Houses but is enhanced because it was conceived by Ray Johnston with an ultra-low embodied carbon footprint in mind, utilizing C-Crete, which is free of Portland cement and CO2 emissions — something Eichler could never have imagined.

The project, totaling ~200 cubic yards of C-Crete, started with ~50 cubic yards for the house's foundation, detached guest room, and detached garage. The remainder will be used for pouring walls, slabs, driveways, and a swimming pool, where C-Crete will be applied via shotcrete. For this project, a boom pump with several sharp angles was employed to deliver C-Crete, which intriguingly flowed from the tube like ice cream!

Last month, C-Crete was poured in a 3-story ground-up residential building near Toronto, marking the first-ever use of cement-free concrete in the entire Canada. The project, totaling 400 cubic yards of concrete, commenced with 60 cubic yards poured for the footings, with the remainder earmarked for walls, columns, slab-on-deck, driveway, etc. Unlike the US, there was no direct ASTM C1157 standard code or a precedent for pouring Portland cement free concrete in Canada. However, the building owner, Trevor, navigated these challenges by leveraging the closest equivalent standard code in Canada (with inputs from C-Crete). His persuasive efforts convinced both the building inspector and structural engineer, paving the way for future adoption of this eco-friendly product in Canada. With Canada's harsh winters, this pour stands as the ultimate durability test for C-Crete under extreme conditions.
