Sika® Stabilizer DF 880
(former MasterRoc® DF 880)
Conditioning agent for aggregates and waste water recovered from the excavation phases in tunnel-boring machine projects
Sika® Stabilizer DF 880 is an admixture designed for the conditioning of aggregates and waste water recovered during excavations using tunnel-boring machines (TBMs) both with Earth Pressure Balance (EPB) and with hard-rock systems that have been treated with Sika® Stabilizer SLF foaming agents or Sika® Stabilizer ABR anti-abrasion agents.
It will prevent the formation of foam in order to permit the use of aggregate in the production of concrete or handling of waste water through the
treatment plant.
Suitable for use in hot and tropical climatic conditions.
- Eliminates air generated by the use of chemicals for soil-conditioning for TBM.
- Applicable for both EPB systems and for hard rock TBMs.
- Improves mechanical strengths of the concrete produced with recovered aggregates.
