Setting Accelerators
Project requirements, particularly in underground construction, can be especially demanding. Applications often require shotcrete set accelerators capable of rapidly developing high compressive strengths to allow fast and safe excavation.
Alkali‑free set accelerators are frequently required to prevent the migration of alkalis into surrounding soils and groundwater. Sika provides a range of solutions designed to meet these requirements.
Admixtures
Sika shotcrete admixtures are designed to maximize performance and efficiency on site. They provide a significant reduction in rebound and reliable mechanical performance, contributing to optimal, productive, and durable applications, even under the most demanding conditions.
Fibers
Sika develops advanced fiber solutions that strengthen and enhance the performance of shotcrete. Its range of synthetic and steel fibers improves crack control, energy absorption, and overall structural integrity, making them ideal for tunneling applications.
