SikaGrout®-380

(former Davco® Grout 380 ECO)

HIGH FLUIDITY NON SHRINK GROUT

SikaGrout®-380 is a one component, shrinkage compensated grout which is specially formulated to have a lower embodied carbon foot print. SikaGrout®-380 specially formulated with special additives for high fluidity and is ideal for pressure grouting, requiring only on-site addition of water to provide a non-shrink free flowing grout.

SikaGrout®-380 is an environmentally friendly product.
  • It is non gaseous, free of bleeding, settlement and shrinkage.
  • Consistent good performance as all ingredients are premixed in the factory.
  • High early and ultimate strength.
  • Eliminates shrinkage in both plastic and hardened phases.
  • Increased strength when fully restrained.

Usage

SikaGrout®-380 is suitable for use in all grouting situations where shrinkage is undesirable.
Primary uses are:
Bedding,Filling and grouting applications where complete filling of voids with a high strength non-shrink material is required.  
Anchoring of mechanical equipment and steel bars:
  • Grouting to machine baseplates
  • Bedding bridge bearings
  • Under-plate grouting.
  • Repairs to precast concrete
  • Anchor bolt fixing
  • Cable grouting and crane rail assembly.

Application steps

SURFACE PREPARATION

All surfaces must be cleaned and free of oil, dust, paint, curing compound etc. Thoroughly damp all surfaces before starting and keep in a moist condition during placing.

MIXING

Damp the grout mixer with water prior to mixing the initial batch of SikaGrout®-380. Ensure that the mixer is free of standing water. Add the premeasured quantity of water. Slowly add the SikaGrout®-380, mixing continuously for at least five minutes until a homogeneous consistent grout is achieved.

APPLICATION

Underplate
Check that the formwork is sealed against grout leakage and that a minimum hydrostatic head of 100 mm can be maintained. Ensure sufficient material is available to complete the work and obtain a continuous fill. Pour from one side only to avoid air entrapment, keeping a head on the grout to promote flow. DO NOT vibrate, but rods, straps and chains can be used to aid complete filling.


Preplaced Aggregate Grout
Grout should be pumped or poured into place. Compressive strength development and ultimate strength of the concrete are reduced slightly
compared with flowing grouts.

Grouting Large Volumes
For grouting thickness greater than 50 mm, the addition of clean well-graded 10 mm aggregates is recommended to reduce temperature rise. Use a 2.5 part of grout by weight to maximum of one part aggregate. Conventional concrete pan mixers and pumps can be used for mixing and placement.

Pumping
SikaGrout®-380 may be placed using piston, ram or diaphragm type grout pumps fitted with ball valves.

CURING TREATMENT

Immediately after finishing, exposed area should be thoroughly cured with water or curing compound.
