K 5 Anchor Grout is supplied as a two part system, pre-measured blend of polyester resins, with selected graded fillers, which, when mixed, offer a high strength, fast setting, fast curing grout of thixotropic consistency. The mixed grout will harden to give rapid strength gain. Designed for the anchoring of steel bars and bolts into concrete, machinery and brickwork.

Uses :

K 5 anchor grout can be used for a permanent installation of reinforcement doweling and starter bars, foundation bolts, base plates, hand rails, safety fences, wall tiles, railway tracks, tie back anchors and grout for tower cranes. Due to its thixotropic nature K 5 anchor grout can be used in vertical, horizontal and overhead situations where the hole diameter exceeds the bar diameter by not less than 4 mm and not more than 25 mm. Designed for the grouting and anchoring of steel bars and bolts into concrete, stone, machinery and brickwork where speed of installation and early load bearing capacity is required.


Advantages :

• Pre packed easy to use water proofing coating.
• Rapid strength gain
• Vibration resistant
• Corrosion resistant
• High early strength
• Extremely durable
• Weather resistant
• Can be used in damp conditions
• Fast setting and self curing.
• The hardened grout is resistant to chemical attack from many chemicals and petroleum products.

Typical Properties:

Compressive Strength : 24 hours - 50 N/mm2; Ultimate – 85 N/mm2; Pot life - 15 minutes at 30OC; Density - 1.92 gms/cc (Typical axial pull out strength is 48 N/mm2 in concrete using mild studding in holes drilled by rotary percussive equipment.) Temperature range in application : 0OC to 40OC; In service : -20OC to 60OC.


Failure in all cases was in the concrete. Chemical resistance-cured K 5 anchor grout is resistant to water, oils, petrol greases and mild acids and alkali solutions. Anchor design : The strength of the cured K 5 anchor grout permits the production of anchors capable of high loadings. The ultimate load will be governed by the following factors : l Strength of substrate. Length of bond. Dimensions and type of bar l Hole drilling and preparation

Application Instructions :

Preparation : Hole should be formed using rotary percussive drilling techniques. Diamond drilled holes should be scrabbled or undreamed. Pre-cast holes should have roughened sides. All dust and drilling debris should be removed. Bars and bolts should be degreased and all rust removed. MIXING : 5 K 5 anchor grout is supplied in preweighed two packs. The content of plastic bag should be emptied in metal container, mixed thoroughly to form a smooth paste. Once mixed two component use it in one operation. Bigger pack can be mixed as required by mixing / volume of the resin component with 2 volumes of the powder.


Installation : The grout should be injected to the bottom of the hold to avoid entrapment of air. Due to its thixotropic nature, loss of K 5 ANCHOR GROUT from the hole will be insignificant. K 5 anchor grout is designed for use where the gap between the hole 3 and bar is 12 mm or less. Cleaning: All equipment should be cleaned with solvents


Packing :

• 1 KG.

Shelf Life ::

6 months storage life when stored in original unopened container at between 5 ºC to 45 ºC in a dry and shaded place.

Cement Grout K add is plasticising, shrinkage compensating grout additive. A single pack powdered admixture which, when added to cement (cement : sand), produces an easy flow, high strength, shrinkage compensating grout.

Uses :

Ideally suited for grouting and in-filling where a non-shrink, free-flowing product is required. K add imparts super-plasticising / high water reducing properties as well as positive expansion.


Advantages:

• Pre packed easy to use water proofing coating.
• High fluidity.
• Reduced water: cement ratio. Higher strength.
• Iron free.
• Chloride free.
• Excellent adhesion.
• Eliminates shrinkage.
• Economical for non critical static load grouting

Dosage:

200 gm of k add, when added to 50 kgs. Oof cement, will require approx. 20 ltrs of water, the yield of grout being about 25 ltrs. With a 1:1 sand / cement mix the same quantity of k add with the required per 50 kg. O of cement, and the addition of a similar quantity of water results to yield approx. 55-58 ltrs.

Application Instructions :

The substrate should be sound, clean and free from contamination. Concrete surface should be carefully pre-wetted and all surplus water to be removed prior to grout application. The k add should be added to the pre-mixed sand/cement (or cement only) and the mixed material gradually of mixing. Grouts made with k add may be applied at temperatures between 50c and 400c. The pouring side should be raised by means of a hopper or grout box to maintain a minimum 150mm head of grout at all times. Clean all equipments immediately after use with clean water.


Curing:

Protect any exposed grouts from severe weather conditions during the early stages for cure by the use of hessian, polythene sheet water application or by k cure c curing aid.


packing:

• 200 gm in sealed plastic container/pouch.

Shelf Life:

Flowgrout epx epoxy grout is an epoxy resin based grout with high flow properties capable of placing in gaps between 35mm to 75mm. The epoxy resin formulation enables flowgrout epx epoxy grout to be used in the most demanding situations giving exceptional mechanical strength. The volume stable mix design ensures complete fill of the grouted area and contact with the work piece. The formulation gives good chemical resistance to most chemicals. Stable to sea water, petroleum products, resists freeze thaw cycles.


Uses:

• It is to be used machinery base plates, crane rail tracks, bridge bearings, compressor, pumps and turbines.
• It can be used reciprocating machinery
• It should be used where minimum shut down time for production machinery is of primary consideration.

Advantages :

• The formulation gives good chemical resistance to most chemicals. Stable to sea water, petroleum products, resists freeze thaw cyles.
• Improves low temperature strength development.
• Excellent adhesion propery.
• Very high and ultimate strength.
• Minimum production shut down.
• Self curing, no need for damp curing or membrane curing compound.
• Resistance to vibration and impact, particularly applicable where cycle of compression/tension make cementitious grout unsuitable.
• Flowable and self leveling for easy placement.
• Excellent volume stability maximum bond and load transfer.

Application Instructions :

Surface Preparation :

• Remove laitance and all loose material including dust, oil and grease to achieve a sound substrate. Steel surfaces should be free of mill scale and
• Rust. Surfaces to be grouted should be free of standing water and in surface dry condition. Formwork must be designed with sufficient
• Hydrostatic head to ensure grout flow into and across the grouting area and should be made grout tight. Apply a silicone based release agent to the formwork surfaces which will effect release after grout has hardened. Alternatively use thick polythene sheet firmly fixed to the formwork.

Mixing :

Flowgrout epx epoxy grout has 3 containers per pack. All containers must be used to complete the mix. Pour all of the resin and hardener into a clean mixing vessel. Mix with a slow speed drill and grout stirrer until homogeneous. Slowly add the filler to the mixed resin and hardener. When all the filler has been added, mix for a further two minutes until an even colour is achieved. Larger volume may be mixed using a forced action mixer such as the creteangle.

Placing:

Place grout continuously into the work area from one side only. Where further mixes are required to fill the void, these should be prepared in sequence such that pouring is continuous. Place mixed grout within 20 minutes after start of mixing. Place in gap widths between 35mm and 75mm. Do not disturb the grouted section until the grout has hardened. Tools and mixing equipment should be cleaned with solvent before grout has hardened. Set grout can only be removed mechanically. Flowgrout epx epoxy grout may be placed at temperatures between 5°c and 45°c. For placing outside this range contact the technical service department.

Curing:

• No special curing is required.
