Alkali-Free Liquid Accelerator

Alkali-free · low rebound · strong later-age strength — For shotcrete. Fast initial and final set, with an alkali-free formulation that dramatically reduces harm to both the crew and the concrete's later-age strength.

Overview

The alkali-free liquid accelerator drives rapid set in shotcrete for tunnel and mining support, cutting rebound and dust. The alkali-free chemistry avoids the later-age strength loss typical of conventional alkaline accelerators, and is far kinder to the crew.

Applications

Tunnel primary support, mine roadways, slope stabilisation and other shotcrete works.
