Drizoro Maxrite®700 to repair damaged concrete

Technical Data | MSDS| Specifications

Drizoro Maxrite®700 is a single component, cement-based, microsilica and polymer-modified, fiber- reinforced restoration mortar with corrosion inhibitors. Maxrite has been specially designed for high performance. Protects structural concrete repairs where exposed to aggressive environmental conditions. Provides an additional protection of the steel reinforcements. Its long open time and thixotropy allows for the repair damaged concrete whether new or old. Repairs to the concrete are simple without the need of form work and can be applied manually or by mechanical means.

Application fields

  • Maintenance of industrial areas damaged by aggressive environments, acid rain, atmospheric pollution, etc.
  • Structural concrete repair affected by corrosion of reinforcements in marine environment, bridges, harbours, dams, etc
  • Repair of concrete structures with carbonation process.
  • Repair of damaged concrete by deicing salts, freeze/thaw cycles, mechanical impacts, etc.
  • Concrete repair affected by repeated loads.
  • Repair of prefabricated concrete elements.

Advantages of Drizoro Maxrite700 to repair damaged concrete

 

  1. Corrosion inhibitors prevent corrosion against chlorides and aggressive corroding agents, extending considerably the service life of the structure.
  2. It’s open setting time allows the quick completion of the repair of large surfaces.
  3. Good chemical resistance in aggressive environmental ambient due to its microsilica content.
  4. Waterproof.
  5. Withstands freeze/thaw cycles.
  6. Offers high resistance to carbonation penetration.
  7. High adhesion to concrete and reinforcements.
  8. Does not require special primers.
  9. The transmitted Loads onto the repaired structure.
  10. High impact and mechanical strength.
  11. Long lasting repairs.
  12. Good thixotropy.
  13. Application in successive layers without slump or the need to use formwork.
  14. Allows high thickness per layer.
  15. Easy workability and application. Repair damaged concrete can be completed by spray with the use of the wet-method.
  16. Single component mortar. Only requires water for mixing and it is odourless,
  17. Suitable for poorly ventilated areas such as tanks.

APPLICATION INSTRUCTIONS

Preparation of the surface:

Drizoro Maxrite700 before repairs

Before repairs with Drizoro Maxrite700  – rusty reo exposed

Remove damaged and loose concrete. Clean cut the edges perpendicularly to a minimum depth of 5 mm. Expose all corroded reinforcement. Remove all concrete until reo bars no longer show rust. Clear concrete all around the reinforcement for an efficient cleaning and to surround it with a minimum thickness of at least 1 cm. of MAXRITE®700.
Remove the rust by wire brush, needle gun, sand or shot blasting, etc.
For additional protection, an application of the oxide converter and protector Drizoro Maxrest Passive – (steel corrosion inhibitor) is be applied to the reo. Prior to application of Drizoro Maxrite®700, dampen the exposed surface until saturated but do not leave free-standing water.

Mixing:

 Drizoro Maxrite®700 is mixed exclusively with clean water, free from contaminants,  either manually or mechanically by low speed drill (400 – 600 rpm).
One 25 kg. bag or drum of Drizoro Maxrite®700 requires about 3,75 to 4,25 litres of water to achieve proper consistency of a repair mortar (16% ± 1%).
For applications using pump or spray machines the mixing water can by increased up to 4,5 litres per bag.
Quantities are only indicative, onsite testing for the desired consistency and the existing ambient conditions.

Application:

Drizoro Maxrite700 after repairs

After repairs with Drizoro Maxrite700 

For an optimum bonding prepare a slurry, mixing 5 parts of Drizoro Maxrite®700 with 1 part of water, mixing thoroughly until a homogeneous  consistency without any lumps is achieved.
Apply the slurry using a Drizoro Application Brush on the surface to be repaired and on the reinforcement bars, filling all voids and pores. While the slurry is still fresh, start placing Drizoro Maxrite®700. Use a consistency of a repair mortar.
Apply the layers between 5 and 50 mm thick.
Attention:-
Trowel on the Maxrite mortar whilst pressing with the trowel. This prevents any air entrapment.
Mark or scratch the surface of each layer with the trowel to improve the adhesion of the following coat, which can be placed after about 30 minutes. Shape the last layer as desired before the final hardening occurs.
Once the repair is finished it can be coated with cement -based coating MAXSEAL (Technical Bulletin Nº.: 01) or Drizoro Maxseal Flex (Technical Bulletin Nº.: 29),

Application conditions:

Do Not Apply when –

  • at temperature below 5 °C.
  • When lower substrate or ambient temperatures (<5°C) are expected during the 24 hours following the repair.

Curing:

Under extreme conditions of wind or heat, lightly spray water over the repaired areas for at least one hour.
Recommended repairs be covered during the first 24 hours, if the temperature is above 30 ºC and the relative humidity is below 50%.

Cleaning:

Clean Tools and equipment immediately with water after use. Once set cleaning of material can only be removed by mechanical means.

CONSUMPTION:

Estimated consumption of Drizoro Maxrite®700 are approximately 1.85 kg/m2 per mm. thickness.
One 25 kg. sack of Drizoro Maxrite®700 fills approximately 13.75 litres
Fills 0.54 litre/ kg of Maxrite.

IMPORTANT CAUTIONS

Should the slurry primer dry, or the previous layer is completely set, apply a new slurry coat to continue the job.

DO NOT use 

  •  any Drizoro Maxrite 700 leftovers to prepare a new batch.
  •  when mixing methods which cause violent mix and do not mix for prolonged periods.
  •  curing compounds on the repair.
  • ever exceed the thickness per layer in application.
  • exceed the amount of mixing water recommended.
Setting time is measured at 20 ºC. Higher temperatures reduce setting time. Lower temperatures delay setting time.

For any other application not specified in this technical bulletin consult our Technical Department.
