First, product outline:
The Concrete waterproofing agent is the inorganic nature rigid water-repellent. This medicinal preparation mixes in the concretes or the mortar, improves the concretes and the mortar intensity greatly, impervious and so on many performance, it satisfied has released, wells up, drenches, leaks, infiltrates and so on each kind of different flood project the need. Is suitable in each kind of different marking Portland cement, this each technical specification examination already JC474-1999 top-quality product standard.
Second, homogeneity target:
Project | Target | Project | Target | |
Outward appearance | Powder | Powdery | Cement only thick liquid mobility | ≥160mm |
Fluid | Liquid | Including solid quantity, % | 40±2 | |
Water content, % | ≤5 | Chloride ion content | Does not have | |
Degree of fineness | 0.315mm triage ≤12% |
|
|
Third, major technique performance:
1st, mixes the quantity (cement load ratio) 6-8% (medicinal powder), reduces Shui Lvke to achieve 15-20%.
2nd, the compressive strength enhances 20-50%, anti-mixes the marking to be bigger than S15.
3rd, the improvement concrete workability, does not segregate, not weeping.
4th, when does not need to enhance the intensity, may reduce the cement content 10%
5th, hurries the non-corrosion function to concretes in vivo.
Fourth, applied technology main point:
1st, the medicinal powder may first mixes evenly with in the cement and the aggregate, in mixes in the quota to mix in the water to stir. The liquid may join in the water to stir directly.
2nd, spikes when should measure, to cease precisely leaks mixes or repeatedly spikes.
3rd, for the guarantee best use effect, suggested that the user first uses this or exchanges in the cement variety before the project should act according to the project the specific request, after tries to match the experiment to determine that mixes the quantity best.
