SikaGrout®-810

(former MFlow 810)

NON SHRINK, CEMENTITIOUS GROUT FOR USE IN GENERAL CIVIL ENGINEERING WORKS

SikaGrout®-810 is a ready to use, non-shrink, natural aggregate cementitious grout for use in general civil engineering works. SikaGrout®-810 provides extended working life and high early and ultimate strengths.

  • High strength - Provides good early and ultimate strengths which ensure quick return to service and long term durability.
  • Non shrink - Hardens free of bleeding,settlement and drying shrinkage when placed at flowable consistency
  • Flowable consistency - Ensures complete filling of even intricate voids often without the need for pumping and strapping.
  • Ample working time - Remains placeable up to 1 hour, even at high ambient temperatures
  • Dense, impermeable grout - Provides a good watertight seal.
  • Economical - Greater volumes of grout can be mixed and handled with less labour.
  • Easy to use - requires no special mixing equipment, it can be mixed in a pail using a grout stirrer.
  • No added chloride - Does not add to chloride load on structure.
  • Provides complete non shrink performance - When tested in accordance with simulated Bedplate Technique.
  • Versatile - Can be placed from flowable to trowelable consistency

Application steps

SUBSTRATE PREPARATION

The substrate should be properly prepared and should be free from contamination, laitance and loose material. Thoroughly saturate the substrate with water at least 2 – 3 hours prior to pouring the grout. All free water ponding should be blown out of the void just before pouring the grout.

MIXING

Water addition may be affected by temperature conditions on site. Trials are recommended to determine the correct water requirement. SikaGrout®-810 should be mixed using a suitable mixer. For flowable consistency, use a hand drill and paddle for small works up to two bags at a time and specialise grout mixers for larger volume. Drum type mixers may not provide sufficient mixing efficiency to derive the optimum performance from the grout. The correct volume of water should be added to the mixer followed by the powder. Mixing should continue until the grout has a smooth, lump free appearance. This will normally be between 3 – 5 minutes after mixing has started.

APPLICATION

Carefully remove the formwork once theSikaGrout®-810 is self-supporting and cut the shape of the shoulder with a trowel. Preferably the shoulder should be cut to a 45° angle to minimise stresses.

CURING TREATMENT

As for all cementitious materials, curing is essential to prevent rapid drying out of the grout and shrinkage caused by the water loss. Curing should be effected by accepted methods such as curing compounds, polythene sheet, wet hessian or water ponding. If a shaped shoulder is required, it should be formed before the grout has reached its final set.

CLEANING OF TOOLS

Clean tools and equipment with water before SikaGrout®-810 has hardened, otherwise mechanical cleaning will be required.
