CEMflex LCA 115 is an easy-to-use, economic, liquid crystalline waterproofing concrete admixture. The product creates a crystalline 'nano' structure within the concrete matrix, reducing the diameter of capillaries and sealing off any micro-static cracks.The reaction takes place with the free lime in concrete pores and capillaries, creating a permanent reduction of water permeability. The crystalline effect allows the structure to self-heal shrinkage cracks when exposed to water.It is mixed into the concrete either at the batching plant or in the mixer truck on site.Features and benefits:The concrete self-seals both existing and future static cracks of up to 0.4 mm.Properly formulated mix designs result in waterproof concrete resistant against 13 bar (maximum).Quick dispersion; easy to mix with no lumping or need for extensive mixing times.Minimal influence on concrete segregation.Increased resistance against low-ion soft water and aggressive media with a pH range of 3–12.Suitable for potable water.Applications: Typical application fields include waterproofing of concrete:Basements and below-grade parking structures.Potable water structures.Sewage-retaining structures.Tunnels and pipes.On-grade slabs, ramps and pile caps.Providing waterproof shotcrete.Concrete treated with the admixture may discolour or show efflorescence once in contact with water. This is normal and mainly caused by the crystalline reaction. The discoloration does not affect performance. Spillages are easily removed and cleaned with water.Concrete requirements:Waterproof concrete requires several measures to ensure a dense structure.Cement: The admixture can be used with most CEM I–III R and N (ASTM Type I–V) cements. Only cement types with more than 50% pozzolanic content are not suitable. Cement content must be at least 280 kg/m³.Fly ash: Total fly ash content must be less than 50% of the total cementitious content.Water: Potable water quality with a maximum dosage of 55% to total cementitious content (water:cement ratio <0.55).Pozzolans: Additives like Microsilica and slag compete with CEMflex LCA115 for the available lime. Laboratory tests should be conducted beforehand to determine suitability, especially when 'pozzolanic-containing' cements are used.Aggregates and sand: Ensure a proper sieve curve according to good concreting practice such as outlined by the ACI guidelines.Admixtures: The product is compatible with most concrete admixtures. Mixes containing strong water reducers or super plasticisers must undergo suitability tests to avoid possible segregation, especially at high dosage rates.Rebar: Amount and layout of reinforcement must be planned to minimize the risk of crack development. The rebar design is not influenced by the use of CEMflex LCA115.Colour:Clear.Technical characteristics:Density: 1.16 kg/L.Water permeability according to EN 12390-8: 13 bar (190 psi) positive and negative side.Compressive strength (compared to untreated concrete): ±0% after 28 days.Fire rating to EN 13501-1: Class A1.Dosage per m³ concrete: Varies with water percentage used.

The reaction takes place with the free lime in concrete pores and capillaries, creating a permanent reduction of water permeability. The crystalline effect allows the structure to self-heal shrinkage cracks when exposed to water.

It is mixed into the concrete either at the batching plant or in the mixer truck on site.

Features and benefits:

  • The concrete self-seals both existing and future static cracks of up to 0.4 mm.
  • Properly formulated mix designs result in waterproof concrete resistant against 13 bar (maximum).
  • Quick dispersion; easy to mix with no lumping or need for extensive mixing times.
  • Minimal influence on concrete segregation.
  • Increased resistance against low-ion soft water and aggressive media with a pH range of 3–12.
  • Suitable for potable water.

Applications:

Typical application fields include waterproofing of concrete:

  • Basements and below-grade parking structures.
  • Potable water structures.
  • Sewage-retaining structures.
  • Tunnels and pipes.
  • On-grade slabs, ramps and pile caps.
  • Providing waterproof shotcrete.

Concrete treated with the admixture may discolour or show efflorescence once in contact with water. This is normal and mainly caused by the crystalline reaction. The discoloration does not affect performance. Spillages are easily removed and cleaned with water.

Concrete requirements:

Waterproof concrete requires several measures to ensure a dense structure.

  • Cement: The admixture can be used with most CEM I–III R and N (ASTM Type I–V) cements. Only cement types with more than 50% pozzolanic content are not suitable. Cement content must be at least 280 kg/m³.
  • Fly ash: Total fly ash content must be less than 50% of the total cementitious content.
