DESCRIPTION

The Microsilica gel RB-MS386 for concrete is developed to make high-strength, waterproof, impermeable and high-durable concrete which is one of the best types of microsilica. This product contains microsilica powder and polycarboxylate superplasticizer for improving performance. Microsilica gel RB-MS386 maximize service life of structure by increasing concrete strength against physical, chemical, environmental and even internal destructive factors of concrete.

APPLICATION FIELDS

  • Different types of reinforced and unreinforced concrete structures
  • Waterproof concrete tanks and reservoirs.
  • Marine structures, water transfer channels and tunnels.
  • Heavy anti-radiant and explosion-proof structures.
  • Structures exposed to abrasion, bridge decks and parking structures.
  • Projects requiring decrease in concrete permeability for high-durability.
  • Projects requiring high-strength concrete to reduce dimensions of the structure elements or increase span length.
  • Structures requiring high elastic modulus.
  • Precast concrete elements.

FEATURES

  • Reduces water-cement ratio
  • Reduces cement content in concrete, at least 20 percent
  • Increases workability and workability retention of concrete
  • Increases flexural,  tensile  and  compressive strength of concrete
  • Achieve to early compressive strength of concrete
  • Improves pumpability of concrete and reducing depreciation of concreting equipments
  • Improves concrete consistency
  • Enables economies in mix designs to be achieved when special conditions such as chemicals attack, dynamic load, etc.
  • Considerably reduces permeability
  • Increases durability of concrete
  • Reduce damages caused by lack of correct curing method
  • Increases the abrasion resistance of concrete Reduce the risk of cracks in concrete

DOSAGE

The optimum dosage of RB-MS386 can be determined by trials in the site. Depending on concrete mix design (concrete type, workability, compressive strength, sizes and types of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage of between 4 and 8 percent by weight of cement is recommended.

DIRECTION FOR USE

Add %4 to %8 of total cement, RB-MS386 to concrete. RB- MS386 gel can be added at the time of concrete making in batching or after concrete making in truck mixer. If RB-MS386 gel is added in to truck mixer, be sure of complete mixture of gel and concrete. According to experimental results RB-MS386 should be mixed in truck mixer for 2-5 minutes. To get the best result, use RB-MS386 in two stages. One part of gel into batching and another part as a reminder dose should be added to truck mixer 5 minutes before using.

RB-MS386 can be added to concrete in two ways:

RB-MS386 could be added to ready-mix concrete before placing concrete. RB-MS386 could be added to a part or whole of concrete mixing water then added to the concrete mix.

STORAGE

Shelf life: 1 year in the original package Storage condition: should be protected from direct sunlight and frost. Keep pail in the temperature range between          +10°C and +30°C

SAFETY

This product does not contain any substances hazardous to human health and the environment. However, it should not be swallowed and contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water. RB-MS386 is not flammable.
