Ann Lambrechts developed a revolutionary concrete that opened an entirely new world of possibilities for building professionals around the world by overcoming major technical, structural, and engineering challenges.
Her invention is marketed under the brand name Dramix by Bekaert where she works as a Global Sales and Product Manager. It has inspired architectures to unleash their creativity and realize their visionary work. The CCTV building in China or the entrance to Oceanogràfic aquarium in Valencia, Spain is prime examples.
Ann Lambrechts invented Dramix by adding 55mm flattened hook-shaped ends steel fibers to wet concrete. It boosts the bending tensile strength of concrete by 32%, provides better crack control, and is easy in mixing and handling. Also, because the steel fibers are only 55mm in length, it reduced the cost compared to the older methods where rebar was added to the concrete.
Lambrechts brought a mini-boom in the building and construction world. From home apartments to tunnels, from corporate to public buildings, and from building and civil engineering work to flooring, her invention is being used everywhere. Her contributions to the building material world fetched her European Inventor Award 2011. You can find her patent on Dramix here. Below is a quick snapshot of her patent portfolio.
