Batimix Ret WG2-L

Wet mix shotcrete liquid set-retarding admixture


BATIMIX Ret WG2-L is a synthetically produced set-retarding admixture for shotcrete based on selected gluconate modified organic polymers. It does not contain any corroding ingredient that could potentially attack steel, aluminum, or zinc embedments.

Main Purpose

BATIMIX Ret WG2-L delays concrete setting necessary for placing and finishing operations, particularly in hot climates. It is used to transport shotcrete over long distances or cope with delivery schedules lengthened by traffic jams.

BATIMIX Ret WG2-L extends concrete setting times, essential to eliminate cold joints between adjacent shotcrete layers in large pours. It also helps avoid concrete hardening because of slow casting rates.


Shotcrete prepared with BATIMIX Ret WG2-L is characterized by the following:

In the plastic state:

  • Prolonged and controlled rates of setting
  • Reduced cold joints or other discontinuities
  • Improved slump retention and finishing times

In the hardened state:

  • Reduced water permeability and cracking
  • Non-staining and better surface appearance
  • Improved shotcrete durability
