CEMEX launches ready-mix concrete brand
CEMEX, S A B de CV has launched Promptis®, a rapid-hardening, fast-formwork removal concrete technology. Promptis® is able to reach early compressive strength in as fast as 4 hour, compared with an average of 18 hour in conventional concrete. Despite its rapid-hardening properties, Promptis® has been designed to retain workability for over 90 minute, 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 ing. 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. 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 industrialisation 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.
