imi Concrete adds CarbonCure technology to concrete plants

Published by
World Cement,

A concrete and materials provider headquartered in Greenfield, Indiana, Irving Materials Inc. (imi Concrete) has adopted the CarbonCure CO2 recycling technology in 15 of its ready-mixed concrete plants across Indiana, Kentucky, and Tennessee.

On average, every 1 yd3 of concrete that is made by imi Concrete with the CarbonCure Technology will save 25 lb of CO2. This will reduce the carbon footprint of the company’s concrete.

The technology works by injecting recycled post-industrial CO2 into concrete during the manufacturing process. Concrete producers are able to optimise concrete mixes without impacting the concrete’s quality or price, as the CO2 undergoes a mineralisation process that enhances the compressive strength of the concrete.

CarbonCure was first installed at imi Concrete’s Whiteland plant in Indiana in July 2017. There, the company conducted extensive testing, expanding coverage of the carbon-reducing technology with three plant installations in November 2018. A further 11 plants are scheduled for installation in early 2019. The concrete made with recycled CO2 will be available to developers and contractors from select imi Concrete locations by early Spring.

“imi Concrete is a family-owned and community-orientated business,” said Bob Haldrup, President of the North Division at imi Cement. “We are proud and humbled to provide the high-quality concrete products that make up the structural backbone of our communities. imi Concrete has been at the forefront of concrete innovation, including the development of the front discharge concrete mixer that is now an industry staple. CarbonCure fits within our vision to lead our industry with forward-thinking processes that provide better products for our customers.”
