| Cemex launches its first global ready-mix concrete brand Mexico's Cemex, the world's No. 3 cement maker, announced 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. write your comments about the article :: © 2011 Construction News :: home page |
