CarbonCure achieves AASHTO compliance as a concrete admixture

The American Affiliation of State Freeway and Transportation Officers (AASHTO) has verified that ready-mix concrete made with CarbonCure is compliant with its requirements as an admixture for concrete.

The verified compliance will give state transportation companies, contractors, and engineers the arrogance to combine CarbonCure’s CO2-injected concrete admixture into their tasks. The know-how can assist advance infrastructure development with diminished CO2 emissions.

This analysis of CarbonCure concrete was carried out by SGS TEC Companies — an impartial, accredited laboratory in Lawrenceville, Georgia — following the Distinctive, Patented, Proprietary Merchandise (UP3) testing protocol managed beneath the AASHTO’s Product Analysis & Audit Options. The concrete batching occurred at Thomas Concrete’s facility in Doraville, Georgia, and the AASHTO testing program centered on the impact of injecting CO2 into concrete. 

Concrete properties of three management mixtures and three CarbonCure mixtures had been examined in accordance with AASHTO M194 (ASTM C494) by the impartial laboratory, evaluating droop, temperature, density, yield, air content material, compressive power, flexural power, and resistance to speedy freezing and thawing. Briefly, the CarbonCure mixes carried out equally to the management mixes and met or exceeded the job necessities specified by AASHTO. Further sturdiness testing additionally resulted in no detrimental affect on hardened concrete properties and confirmed the efficacy of CarbonCure in assembly and, in some cases, exceeding business requirements.

5 U.S. state departments of transportation have already added CarbonCure to their authorized product lists. These embody Colorado, Hawaii, Iowa, North Carolina, and South Carolina. Hawaii’s HDOT was the primary to approve CarbonCure in 2019. 

“This validation not solely highlights the standard and security of CarbonCure but in addition affirms our dedication to sustainable infrastructure growth,” added Robert Niven, CarbonCure’s CEO. “We’re excited concerning the large quantity of DOT tasks and new enterprise alternatives for our concrete producer companions. We look ahead to many extra state DOTs including CarbonCure to their very own authorized product lists and the constructive affect our applied sciences could have on transportation tasks nationwide.”

The compressive power achieve ensuing from CarbonCure’s carbon mineralization answer has enabled extra environment friendly use of cement. CarbonCure says that this ends in a extra sustainable concrete product that meets the surging demand for greener constructing supplies from each the federal government and the non-public sector. 

CarbonCure’s applied sciences have already been used to provide greater than 5 million truckloads carrying greater than 44 million cubic yards (33 million cubic metres) of decrease carbon concrete, saving greater than 348,000 metric tons of carbon dioxide, the equal of taking greater than 77,000 gas-powered automobiles off the street for a yr.
