Blair Block has begun commercial production of the world's first ultra low carbon emitting concrete bricks at its concrete brick facility in Childersburg, Alabama. The new bricks utilize CarbonBuilt's proprietary technology to reduce hidden carbon by 70-100 + percent compared to conventional concrete bricks. Most importantly, the bricks, which are no more expensive to produce than conventional concrete, will be used in the construction of several municipal projects in Alabama. This case demonstrates that carbon emissions from concrete production can be substantially reduced without compromising cost or performance.
The first production line will avoid at least 2,000 tons of CO2 emissions and remove more than 500 tons of CO2 per year. This impact is expected to increase over time through process optimization and the integration of other production lines.
CarbonBuilt's technology replaces most of the expensive high-carbon Portland cement used in concrete manufacturing with a proprietary low-cost cement alternative made from widely available low-carbon materials. These materials harden by chemically reacting with CO2, which is piped from an on-site furnace into the curing chamber, which also generates the heat needed for the process. The furnace uses waste biomass that would otherwise produce carbon emissions. This process not only strengthens the bricks, but also permanently stores the carbon dioxide in solid form.
The first batch of ultra low carbon concrete bricks will be provided by the contractor C & & C Masonry will begin integrating ultra low carbon concrete bricks that meet the same specifications as conventional bricks into existing and new contracts in the coming months. Ultra low carbon concrete bricks will be seamlessly integrated into the project, replacing conventional bricks at no additional cost. Concrete Bricks
Not to Be Ignored More than 100 million humble concrete bricks are produced in the United States each year and play a vital role in the construction of homes, schools, commercial and industrial facilities, given their strength, durability, fire resistance, energy efficiency and noise reduction. Concrete bricks are ideal for construction in areas prone to fires, hurricanes and tornadoes.
Compared with poured concrete, ultra-low-carbon concrete bricks have the potential to reduce carbon emissions, thus becoming an important tool to reduce global emissions, and their low-cost characteristics make concrete bricks have great advantages in accelerating the transition to low carbon in the built environment.
On May 10, Henglong Real Estate Co., Ltd. announced a two-year strategic cooperation with carbon capture, utilization and storage technology enterprises to clear zero carbon. The two sides will carry out in-depth cooperation in the research and development of low-carbon recycled aggregate technology for carbon dioxide mineralization enhanced waste concrete and the application of "clean capture and carbon sequestration concrete solid brick" commercial projects to reduce the embodied carbon emissions of buildings. Hangzhou Henglong Plaza will be the first commercial development project to use solid bricks of carbon fixation concrete.
This cooperation will use carbon dioxide mineralization technology to strengthen the research and development of low-carbon RCA technology of waste concrete through carbon dioxide mineralization, and promote the application of CCUS in Hangzhou Henglong Square.
The two sides will carry out research on resource recycling of waste concrete generated by the development project of Hangzhou Henglong Plaza. Researchers crushed waste concrete into aggregates and made low-carbon RCA through carbon dioxide mineralization and strengthening process. After full life cycle assessment, it is found that low carbon RCA as concrete raw material has significant emission reduction potential compared with ordinary aggregate. Henglong and Qingfu Zero Carbon have completed a small-scale pilot project of low-carbon RCA, and the next step is to carry out pilot-scale production verification for 150 tons of waste concrete.
Both parties will use solid bricks of carbon fixation concrete in the secondary structure wall of the basement of Hangzhou Plaza 66 (the usage can cover the wall area of about 17,000 square meters). Hangzhou Plaza 66 will be the first commercial development project to apply the technology. By replacing cement with industrial by-products such as fly ash and blast furnace slag powder, and relying on its proprietary carbon dioxide mineralization curing process, the carbon emission of carbon sequestration concrete solid brick will be 87.5% lower than that of traditional sintered brick.
