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.

Rapid hardening

✓ Early strengths in as little as 4 hours
✓ Design strengths achieved in 7 days
✓ Up to 40N/mm2 in 18 hours

High performance

✓ Designed with a chloride free accelerator
✓ No risk of corrosion
✓ Excellent workability retention

Fast Formwork removal

✓ Formwork can be stripped in as little as 6 hours, even for slabs

Accelerated construction times

✓ Faster slip for casting cycles
✓ Accelerated precast cycles

Project Spotlight

Hodariyat Bridge - Dubai

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.
