SUTOP® B-21
Categories


✓
APPLICATION FIELD

  • It may be safely used for water insulation in drinking water and waste water tanks,
  • On foundations, reinforced concrete curtains,
  • On pre-cast concrete elements,
  • In dams, tunnels,
  • In underground parking lots,
  • In elevator pits,
  • On mass concretes,
  • In water channels,
  • In water treatment facilities,
  • On piled foundations,
  • In swimming pools.

REQUIREMENTS

  • It is an inorganic fluid mixture used for water insulation in concrete.
  • Renders concrete impermeable against very high water pressure (14 bar) from positive and negative sides.
  • During the curing period, it provides forming of smooth, crystalline fibers in the capillary hole. These fibers reduce hole in concrete and prevent water from passing through the concrete mixture.
  • After curing, it closes cracks up to 0.4 mm with its crystallization effect.
  • Reduces cost in terms of labour and time.
  • It is easy to use.
  • It does not clump during mixing as it is in liquid state.
  • It does not prevent breathing of the concrete.
  • It does not harm the environment.
  • Approved for drinking water.
  • It is continuously active and becomes a permanent part of concrete.
  • Protects the reinforcement against corrosion. It is compatible with all kinds of plasticizers and water reducing additives.
  • It is the best solution for bored piled raft foundation.
  • It has no side effect on hardening and curing properties of concrete.
  • Improves the strength and freezing-thawing resistance of concrete. It has been observed that it improves the strength of concrete by 3% in all tests performed.
  • There is no need for protection as it cannot be damaged.
  • It provides definite and continuous water insulation without requiring any other type of water insulation in concretes.

APPLICATION

PREPARATION of the MORTAR

  • Ensure that the mixture ratio of cement and water for the concrete that shall be added with SUTOP® B-21 is less than 0.55.
  • Thoroughly mix SUTOP® B-21 before using.
  • Application time is approximately 45 minutes after being added to concrete.
  • When type II and III type of Portland cement is used, it is advisable to use setting retarder.
  • Conformity tests shall be performed before use.
  • Crystallization may occur if SUTOP® B-21 is stored below +8°C. The material can be re-used after mixing and homogenizing.

CONSUMPTION

For concretes to be insulated using SUTOP® B-21

  • With a ratio of 2% of the cement amount if Water/cement ratio (w/c) ≤ 0.45
  • With a ratio of 2.5% of the cement amount if 0.45 < Water/cement ratio (w/c) ≤ 0.50
  • With a ratio of 3% of the cement amount if 0.50 < Water/cement ratio (w/c) ≤ 0.55
  • For concretes with Water/cement ratio (w/c) ≥ 0.55; water insulation with SUTOP® B-21 is not suitable.

Dosing at concrete plant:

SUTOP® B-21 may be added to the mixture with the mixture water as the final component.

Dosing at construction site:

SUTOP® B-21 is added to the mixer at a ratio of 2-3% and mixed for 3-5 minutes. Mixing shall be performed without delay.
