Promptis®
Promptis®
Promptis® is a range of high early strength concretes, developed to meet the most demanding time constraints of modern construction projects. Promptis® has similar characteristics to normal concrete but it reaches accelerated strengths just four hours after setting, yet retains workability for up to 120 minutes.
Technical Specifications
Cemex's expert team creates bespoke readymix concrete mixes tailored to your project. We handle challenges such as corrosive ground, extreme weather, and high-strength requirements, working to your specifications or providing solutions to meet them.

Hodariyat Bridge
Dubai, United Arab Emirates
Cemex was chosen as the sole concrete supplier by VSL due to our proven track record with complex technical requirements. The project called for a concrete with exceptional slump, a workability for up to 4 hours on site, and a compressive strength of 32mpa at 30 hours. Cemex supplied over 50,000m³ of concrete to this landmark.
