Explicação, anotação:To get concrete and solutions high strength, watertight, placeability and freezing resistance
Descrição porminorizada da marca:Ëàõòà addition in concrete - dry mixture on the basis of microsilica, plasticizers and active mineral constituents. Possesses by the combined effect:
- increase of concrete strength;
- watertight increase of concrete;
- mobility enhancement of mixture concrete;
- the freezing resistance increase of concrete.
the addition does not reduce protection properties of concrete in relation to steel reinforcement, that allows the use of it when manufacturing the ferro-concrete products.
the typical objects of application.
the hydrotechnical building, bridges, cross-overs, tunnels, objects of civil and industrial engineering.
the instruction for use.
Ëàõòà the addition in concrete in dry kind is introduced at dry solution or concrete Mixture in the moment of preparation in concrete mixer. After mixing in dry kind during 3-4 minutes one can produce the chutting of solution or concrete mix by the water.
the addition mass is not to compile 5 ïðîö. from cement mass in concrete mix.
the change of technical characteristics of concrete:
1. Reduction of water-cement ration in case of
specified mobility, ïðîö. 20-25
2. Viability of solution mixture, hrs.. 2
3. Increase of compressive strength age
28 days, of ïðîö. no less than. 100
4. mark on freezing resistance, no less than. F600
5. Mark increase on watertight, no less than. 6 stages
6. Mobility increase holding constant water amount. With Ïê1 to Ïê5 |
