MAXGROUT®
NON-SHRINK, HIGH-RESISTANCE FLUID MORTAR FOR FILLINGS AND ANCHORAGES

Description

MAXGROUT is a non-shrink mortar formulated from special cement and mineral products with high mechanical properties and fluidity. Contains no chlorides or metallic particles. It comes in powder form, ready to use.

Uses

- Anchoring of pillars in concrete prefabricated structures.
- Filling of steel column bases.
- Structural reinforcement of damaged or weak concrete structures.
- Beam support in bridges.
- Anchoring of bolts, cables, etc.
- Filling of machinery foundation between concrete and steel plates.
- Joints in pavements.

Advantages

- High mechanical resistance.
- Waterproof, fireproof and non-toxic.
- Unaffected by extreme temperatures once set.
- Resistant to repeated loads.
- Contains no chlorides, it is non-corrosive.
- No shrinkage.
- Resistant to water and oil, grease and derivatives.

Application Instructions

Surface preparation. The surface must be clean and free of grease or oils, dust or any other foreign material. Use high pressure air or water to clean concrete.
Thoroughly wash down and saturate with water, but leave no free standing water.

Mixing: Pour MAXGROUT into a clean drum containing part of the mixing water, and start mixing, in order to break up any lumps. MAXGROUT is mixed with water in a total of approximately 12% and 14% of MAXGROUT 's weight (3 to 3,5 litres of water per 25 kg. bag). Mixing is done using a low speed mixing drill for 3 – 4 minutes, in order not to introduce air bubbles into the mix. A concrete mixer can be also used.

Do not use more water than the dosage recommended as risk of shrinkage increases.
Can be mixed by hand, increasing the mixing time until lumps disappear.
The pot-life of the mixture is 15 – 20 minutes.

Placing: Use small mould supplements around placing area to help during pouring procedure if required. Allow 2 to 3 minutes for the material to settle so any air bubbles introduced during mixing can disappear.

The use of a manual vibration element if necessary, will help in filling the volume required.

MAXGROUT is placed simply pouring by gravity directly from the mixing container. If necessary machine pumping applications are also possible. Air vents should be provided to facilitate the exit of air from the space to be filled.

Application temperature. The ideal application temperature is 10-25° C. Do not apply when ambient or application surface temperature is 5° C or less.

Curing. After filling, do not allow moisture to remain on surface. Avoid direct sun contact.

Coverage A 25 kg. bag of MAXGROUT will fill a volume of approximately 12,5-14,5 litres, depending on the mixing water used. (0.5 – 0.58 dm3 / kg.)

Cautions

Do not use for volumes greater than 1.5 x 1.5 mts and of more than 4 cm. deep (Approximately 0.1 m3).
For these volumes add 8 kg. of sand 3 to 5 mm. for each 25 kg. bag of MAXGROUT and mix with between 2.75 to 3 litres of water per bag.

Packaging

25 Kg. bags.

Storage

Twelve months in its original unopened containers, in a dry place at temperatures above 4ēC.

Safety

• Avoid contact with the eyes and skin.
• Use rubber gloves and safety goggles.
• If it comes in contact with the skin, wash with warm water and soap.
• If it comes in contact with the eyes, rinse thoroughly with water and seek medical assistance.
