Features & Benefits
Some application examples:
- Excellent impermeability to water
- Excellent adhesion to iron and concrete
- Excellent resistance to dynamic mechanical stress
- Modulus of elasticity and thermal expansion coefficient similar to those of high quality concrete
- Mapefill GP does not contain metal aggregates and aluminium dust
- Non-toxic, non-corrosive, and chloride-free
Technical Characteristics
Mapefill GP is a preblended powdered grout based on high strength cement, graded aggregates with 1 mm diameter and special additives with an expansive agent.
When mixed with water Mapefill GP is transformed into a very highly fluid grout without segregation that is able to fill intricate spaces.
Mapefill GP, due to its expansive agent, is characterized by a total absence of shrinkage in the plastic (ASTM C827) and hardened phase, and develops early flexural and compressive strength.
Mapefill GP meets all the main requirements for ENV 1504-9 (“Products and systems for the protection and repair of concrete structures; definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements for EN 1504-6 (“Anchoring steel reinforcement”).
Recommendations
- Do not add cement or additives to Mapefill GP
- Do not add water when the mix begins to set
- Do not use Mapefill GP if the bag is damaged or has already been opened
- Do not apply Mapefill GP at temperatures below 5°C
Application Procedure
Technical Information For The Application | |
---|---|
Mixing ratio: - Trowellable mix - Pumpable mix - Pourable mix |
25 kg of Mapefill GP with 3.25-3.75 litres of water 25 kg of Mapefill GP with 3.75-4.25 litres of water 25 kg of Mapefill GP with 4.25-4.75 litres of water |
Permitted application temperature: | Ambient and substrate temperature from 5°C to 40°C |
Pot life: | 1 h (at 20°C) |
Preparing the substrate
- Remove all deteriorated concrete down to sound substrate
- Scarify the surface and eliminate completely dust, oil, grease, debris and laitance
- Soak the sides of the cavity to be filled with water. Before pouring, remove all excess water. To facilitate the elimination of unabsorbed water, use compressed air if necessary
Preparing the grout
Pour up to 80% of the required water (see APPLICATION DATA) into a clean container and slowly add Mapefill GP continuously. Add remaining water to achieve the desired mix. Mix for 1 to 2 minutes with a heavy duty mixer, remove from the sides of the concrete mixer any powder that is not well blended; remix for another 2 to 3 minutes until a fluid homogeneous paste is obtained. According to the quantities to be prepared, a grout mixer or a mechanical mixer can be used paying careful attention to avoid the formation of air bubbles. Mixing by hand is not recommended.
Application (anchoring)
Pour Mapefill GP from one side only in a continual flow encouraging the discharge of air bubbles.
The use of Mapefill GP for connecting precast concrete elements and the filling of rigid joints is recommended for thickness up to 6 cm. It is not necessary to vibrate the grout mechanically; to facilitate the filling of spaces that are particularly difficult, use a wood list or an iron rod.
Grouting of thick section
For filling cavities that have dimensions greater than those indicated, please consult our Technical Service for assistance on 0113 2455450 (option 2) or send a message to [email protected].
Precautions To Be Taken During And After Application
- At temperatures around 20°C, no particular precautions are required
- In hot weather it is advisable not to expose the material to sun and to use cold water in preparing the mix
- In low temperatures it is advisable to use water that is at 20°C
- After casting, Mapefill GP must be properly cured; the surface of grout exposed to the air must be protected from rapid water evaporation that can cause the formation of surface cracks due to plastic shrinkage especially in hot and/or windy weather
- Spray water on surface exposed to air the first 24 hours of curing or apply an antievaporant
Cleaning
Fresh grout can be removed from tools with water. After curing, cleaning becomes very difficult and can only be done mechanically.
Consumption
Every 25 kg bag of Mapefill GP can yield 13-14 litres of grout.
