New sustainable cement mix could transform construction

AEEE’s new Ultra High Performance Cement mix could reduce carbon emissions usually associated with cement production

Cement production represents 8% of yearly global carbon emissions, according to MJ Said, CEO of AEEE Capital Holding &Advisory Group.

“Cement is one of the most-consumed products on the planet,” Said said.

The sustainable attributes of AEEE’s new Ultra High Performance Concrete (UHPC) mix could help the construction industry reduce the carbon footprint of cement by 16% by 2030 under the Paris Accord commitments – while raising the bar for the strength of the concrete mix.

AEEE announced a peer review, led by Dr. Maher Tadros, founding principal of e.construct.US, LLC, of the UHPC mix, and Said elaborated that the review “confirms the unparalleled performance and long-term value of AEEE’s concrete mix.”

Dr. Tadros’ peer review states that AEEE’s proprietary technology could disrupt building and infrastructure construction as the President Joe Biden’s administration finalizes its trillion-dollar federal infrastructure bill targeting more than 10,000 U.S. bridges.

According to Said, the structural life expectancy of bridges built with AEEE new material could exceed 300 years with virtually no maintenance, which is four times the 75-year design life of the bridges currently built.

The UHPC mix has improved compressive strength (48,500 PSI) and increased flexural strength (7,100 PSI, two times stronger than the current market-leading concrete mixes, according to AEEE).

The company also said the new mix results, in combination with unique structural design, in potential savings of up to 47% in total project costs with expedited timetables for construction projects of up to 33%; AEEE’s precast concrete bridge girder system utilizing the AEEE mix has halved weight reduction and virtually eliminated the need for steel rebar.

Although AEEE’s technology is only in commercial use in China and Egypt, the company said it’s actively discussing joint ventures with construction companies and financial institutions around the world for opportunities in North and South America, Europe, Asia and Australia.
