accelerating Admixture Sika® Sigunit® L Sika Abyssinia Concrete Admixtures

Usage

Sika® Sigunit® L accelerates setting of concrete in applications such as:

• Fixing rocks and slopes
• Lining in tunnels, canals, e.t.c.
• Underground structures
• Repairs
• Slope configuration
• Water tanks
• Construction pits and sub-terranean excavations
• Rock and soil stabilisation

Advantages

Sika® Sigunit® L produces increased internal cohesion and adhesion of shotcrete.

• Thick layers can be applied in one application
• Improves adhesion of the shotcrete to walls, rock formations and concrete and thus facilitates overhead application of shotcrete
• Makes it possible to produce a high strength and dense shotcrete
• Easy handling
• Improves watertightness
• Improves adhesion to substrate and reduces rebound and dust production
• Reduces the required layers and increases their width
• Chloride free, does not attack or corrode iron or steel reinforcement

The accelerator’s effect depends on the cement content, type and age, substrate temperature and type, shotcrete temperature, layer thickness and spray process / equipment. The water/cement ratio of the basic concrete mix is another important parameter which influences the acceleration effect of Sika® Sigunit® L.
