Batimix Accelerator 340

Chloride free, set-accelerating admixture for shotcrete


BATIMIX Accelerator 340 is a chloride-free liquid admixture designed to significantly accelerate setting times of shotcrete mixes applied under wet or dry processes. Upon request, this product can be supplied in powder form.

Main Purpose

BATIMIX Accelerator 340 is used for shotcrete applications to build thick sections, vertical or overhead, with a minimum rebound. It allows rapid concrete setting to take place, particularly effective in cold temperatures and unfavorable weather conditions. Applications using BATIMIX Accelerator 340 include all types of shotcrete and sprayed concrete with or without steel embedments.


Concrete prepared with BATIMIX Accelerator 340 is characterized by the following:

In the plastic state:

  • Decreased overtime, allowing same-day finishing Reduced initial and final setting times
  • Improved thixotropic properties, which allow thick sections to be built
  • Minimum rebound and single-pass spray coatings
  • Reduced bleeding and segregation

In the hardened state:

  • Reduced construction costs – no cold weather delays
  • Increased early compressive and flexural strengths
