About this product

Anchor grout is a three-component polyester resin and special catalysed filler that has been developed for anchoring and fixing. The pourable grout is suited for pouring into holes for anchors in floors and slabs. anchor grout rapid is available for cold weather working.

Conforms with BS EN 1504-6.

Initial set times are dependent on ambient temperature. The exothermic reaction of the grout components is also influenced by the bulk of material mixed at any one time.

To avoid wastage do not mix more material than can realistically be used within the setting times above. For ambient temperatures above 25°C, contact Weber Technical Services.


Uses

● Vertical anchorage of bolts and fixings to building and civil engineering work

● Fixings to concrete structures

● Anchor dowel bars to pavements and slabs


Features and benefits

▲ Fast setting action with rapid strength gain allows loads to be applied within 2 hours

▲ Easy to mix and place

▲ Fixing cannot be vibrated out

▲ Economical fixing compared with mechanical fixings

▲ Stronger than concrete in one hour

▲ Part mixing of  anchor grout allows flexibility of use and no wastage of material

▲ Versatile material with fixings to concrete, brickwork and stone


Preparation

Anchoring with anchor grout is primarily dependent on mechanical interlock and not adhesive bond.


The following points should therefore be observed:

1.Create a rough sided dry hole, preferably by rotary percussive drilling. If diamond drilled holes have been made these must be under-reamed or roughened and all dust removed.

2.Use fixings such as deformed bars, threaded bars or bolts which have been degreased and are completely free of rust.

3.Drill holes which are in the range 4–12 mm greater in diameter than the diameter of the bolt or bar. If other dimensions are encountered seek advice from Tasir Technical Services.

4.Ensure a dust-free and dry hole before using anchor grout.


Mixing

11.jpg

Pour the resin into a clean plastic or other suitable container and gradually add the small bag containing hardener. Mix thoroughly. Now add the large bag containing filler and mix until a uniform colour and consistency is achieved. Small quantities can be mixed by hand using a spatula. Large quantities should be mixed mechanically.


Application

When using anchor grout, simply pour the mixed grout into the hole and insert the bolt or bar into the void with a twisting action.

To avoid excess displacement of grout, and therefore wastage, estimate the quantity per hole in advance. This can be done by referring to the table below.


Strength development

The ultimate strength of the fixing is determined by the following parameters:

1.Tensile strength of bar.

2.Anchorage bond strength of grout/bar interface.

3.Shear bond strength of the grout.

4.Shear bond strength of concrete.

5.Concrete cone pull-out failure, i.e. shear strength of concrete and spacing.

With good installation, after a 2 hour curing the anchorage will fully sustain its design load at 20°C, provided the anchorage has been designed correctly with sufficient anchorage depth.


The relationship between pull-out and anchorage depth is expressed by the simplistic rule:

10 kN pull-out force for every 25 mm depth. This rule applies up to depths of 250 mm and the first 50 mm of concrete depth should be ignored due to the possibility of micro cracks in the concrete surface due to the drilling operation.

Ultimate pull-out loads should be verified on site with proof load tests to validate the engineer’s design calculations.


Packaging

Webertec anchor grout is available in 14.3 kg buckets.


Yield

Yield is approximately 6.75 litres.
