Product Description

OMNITEK® Grout 5000 is a cement based, volume stable, flowable anchoring grout, ideally for anchoring of reinforcement steel bars in concrete repair.

Advantages

High early- and final strength properties to strength class C60/75 for structural repair of concrete.
High flowable consistency with long open times for a fast, easy and cost effective application by pumping or pouring.
Self-compacting and controlled volume expansion.
Adjustable grout volume by adding 8/16 crushed washed gravel for void filling applications in application thickness >200mm.
CE certified according to EN 1504-6.

Field of Application

OMNITEK® Grout 5000 is suitable for:

Anchoring of reinforcement steel bars or rods in concrete according to EN 1504-6.
Filling voids, cavities and recesses in concrete structures.

Certification

CE certified according to EN 1504-6.

Product Properties

Technical Data/Properties^(*)

^{(*)Typical values in production control. All tests were executed under a conditioned temperature of 21°C and 65% RH.

(**) For void filling in thickness >200mm, crushed washed gravel (8/16mm) can be added to OMNITEK® Grout 5000 at a ratio of 16kg gravel / 25kg powder.

(***) Compressive strengths measurements based on cubes with length size of 150mm, without addition of gravel.

(****) According to EN 206-1:2001 in combination with DIN 1045-2.}

Application

1. Preparation of Substrate

Substrate preparation has to be according EN 1504-10 part 7.
The substrate has to be free from dirt, grease, laitance, loose concrete, loose particles or layers which could adversely affect adhesion.
Remove all damaged concrete and prepare substrate by sand or grid blasting, high pressure water jetting, or other methods until base concrete is exposed, offering sufficient roughness (bond) and open pores.
The substrate must be pre-wetted with clean water until saturated. The substrate should be damp, but without free standing water.
The substrate must be frost-free and have a cohesion of minimum 1.5 N/mm².
Exposed or corroded reinforcement steel needs to be treated with OMNITEK® CPC.

2. Mixing

The product has to be mixed using a suitable forced action mixer (400-600rpm). The mixing head must be completely immersed in the powder.
Add 4/5 of the required quantity of water into the mixer and mix for 2 minutes. Add the remaining quantity of water. The water content can be varied to obtain the desired consistency. Never use more than the maximum water quantity. Mix for an additional 2 minute until a lump-free, homogeneous mixture is obtained.
The mixing time depends on the type of mixer. 4 minutes is the minimum.
The mixture must be allowed to rest to release air entrapped during mixing.
Once the grout is ready mixed, apply immediately. Do not prepare more material than can be used within the open time of the material.
When the grout starts to set, remix but never add more water.

3. Application

For rebar anchoring, the material should be poured or pumped in one continuous application in the drill hole until the hole is filled. Insert the rebar or thread slowly with a rotating motion until material is overflowed on the surface. Remove any excess of material immediately.
For cavity filling, the material is always and continuously poured or pumped from one side or corner. A dense and non-absorbent formwork is necessary. To prevent air entrapment, sufficient ventilation holes must be provided.
For void filling in thickness >200mm, crushed washed gravel (8/16mm) can be added to OMNITEK® Grout 5000 at a ratio of 16kg gravel / 25kg powder.
Do not vibrate.
When filling large voids, apply the material by using suitable worm/screw pumps.

4. Curing

After treatment has to be according EN 13610 in combination with DIN EN 1045-3.
In warm or windy conditions protect the applied material from dehydration by mist-spraying with clean water or protective tarpaulins until the initial set has taken place.
In cold conditions cover with insulated tarpaulin, polystyrene or other insulating material. Protect surfaces against frost and rain until final set has taken place.
In cold, humid or unventilated areas it can be necessary to allow for a longer curing period, or to introduce forced air movement to avoid condensation. Never use dehumidifiers during the curing period or within 28 days after application.
Formwork should not be removed for at least 48hours.
The after-treatment should be at least 5 days.
The after-treatment should take place as soon as possible, at the latest when the material surface starts to set.
As an alternative to the conventional treatment methods, suitable curing agents can be used to prevent rapid water loss.

5. Cleaning and maintenance

Mixing and application equipment should be cleaned immediately with clean water. Hardened material needs to be removed mechanically.

6. Special remarks

Cementitious materials can lead to incompatibilities under certain conditions in combination with non-ferrous metals (such as aluminium, copper, zinc).
Low temperatures reduce flow and delay the early strength development. High temperatures accelerate the strength development and decrease the open time of the material.
Depending on geometry and application thickness, adding reinforcement steel can be necessary.
Repaired areas can be coated after 7 days with protective or waterproofing coatings depending on the ambient conditions.
