RB-CS HIGH PERFORMANCE MICROSILICA GEL

DESCRIPTION

The microsilica Gel RB-CS is an advanced concrete admixture used for designing high performance concrete and multipurpose concrete mixtures. This product contains microsilica powder, polynaphtalene superplasticizer, waterproofing and air entraining for improving performance. Microsilica Gel RB-CS 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.

Concrete requiring minimum electric conductivity

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 equipment
  • 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 microsilica Gel RB-CS 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-CS to concrete. RB- CS gel can be added at the time of concrete making in batching or after concrete making in truck mixer. If RB-CS gel is added in to truck mixer, be sure of complete mixture of gel and concrete. According to experimental results RB-CS gel should be mixed in truck mixer for 2-5 minutes. To get the best result, use RB-CS 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-CS gel can be added to concrete in two ways:

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

STORAGE
