RAPIZEM® is a grey powdery accelerator, based on calcium sulfoaluminate (CSA), for concrete. It shortens solidification and hardening time to a few minutes. RAPIZEM® is characterized by an extremely high early strength. The pieces produced are therefore fully loadable after a short time.
The recommended dosage is 2-5 parts by weight of RAPIZEM ® to 10 parts by weight of Portland cement, depending on the desired acceleration.
