CEMEX launches its first global ready-mix concrete brand: Promptis®

Monterrey, Mexico. April 5, 2011

CEMEX, S.A.B. de C.V. (NYSE: CX), announced today the launch of its first global brand of ready-mix concrete, Promptis®. The rapid-hardening, fast-formwork removal concrete technology is already being sold in France, UK, Ireland, Israel, Spain, and Croatia and will be made available in Austria, Poland, Latvia, UAE, and Hungary starting in the second half of 2011.

Promptis® is able to reach early compressive strength in as fast as 4 hours, compared with an average of 18 hours in conventional concrete. Despite its rapid-hardening properties, Promptis® has been designed to retain workability for over 90 minutes, thus allowing the material to be easily handled without the risk of sudden hardening, even under extremely hot weather. Its strength develops in a progressive manner as the concrete ages, resulting in a highly durable material that also exhibits a good resistance to shrinkage cracking.

“As a global leader in ready-mix concrete, CEMEX is innovating through a new product that enables our customers to accelerate their construction cycle and consequently reduce total project costs,” said Ignacio Ortiz, CEMEX President for Central Europe and the Middle East. “Promptis® allows our customers to increase efficiency in their projects.”

Promptis, concrete as fast as your ideas

Promptis® uses CEMEX’s proprietary cutting-edge admixture technology, and the company will be able to offer the concrete technology at any of CEMEX´s ready-mix plants providing a reliable product that meets its customers’ performance expectations.

Promptis® technology is the result of two years of research activities carried out by scientists at the CEMEX Research Group AG in Switzerland. The global offering of Promptis® has been possible thanks to a strict industrialization process that ensures the transfer of technology through a close collaboration between Research and Development and Operations. Promptis® complies with specifications established by norms and standards worldwide.

CEMEX is a global building materials company that provides high-quality products and reliable service to customers and communities in more than 50 countries throughout the world. CEMEX has a rich history of improving the well-being of those it serves through its efforts to pursue innovative industry solutions and efficiency advancements and to promote a sustainable future.
