1. Product introduction
JH-Ⅲ is a composite waterproofing agent for concrete and mortar. It can significantly improve the waterproofing and impermeability of concrete mortar and reduce water absorption. It can also make mortar and concrete Other properties have been improved.
2. Scope of application
JH-III can be used in various waterproofing projects, such as civil air defense projects, bridges, basements, water towers, pools, dams, etc. Because JH-Ⅲ waterproofing agent has excellent moisture resistance, it can be used in various industrial and civil buildings to isolate moisture without hindering wall ventilation.
3. Main technical performance: (compared with benchmark concrete)
Dosage (%) 3.0-5.0 Compressive strength increased by 20-90% in 1 day
Increased by 10-40% in 28 days
Water reduction rate (%) 5-10 Water absorption rate (%) Concrete ≤ 60
Ratio of bleeding rate (%) ≤ 80 Mortar ≤ 60
Ratio of bleeding rate (%) 1.5 -3.0 The impermeability of concrete is increased by 30-50%
Initial setting time
Final setting -60～+60
-60～+60 Mortar is increased by more than 50%
Freeze resistance Improved properties
Reinforcement corrosion-free shrinkage ratio (%) 110
Waterproofing agents can significantly improve the impermeability and compressive strength of mortar and concrete, reduce water absorption, and improve secretion. It has water-based, frost resistance and other properties, and has no obvious effect on shrinkage during condensation, and has no rust effect on steel bars. The mortar anti-permeability results are: the blank specimen is gradually pressurized to a constant pressure of 10 kg/cm3 for 3 hours, and all water is permeable; while the specimen mixed with JH-III is continuously pressurized to a constant pressure of 15 kg/cm3 for 6.5 hours, and the water is permeable. The height is only 28mm. The above results fully demonstrate that adding JH-Ⅲ waterproofing agent can give concrete and mortar good waterproof and impermeability properties.
IV. How to use:
1. This product is suitable for various mortars and waterproof concrete with waterproof and impermeability requirements.
2. This product is suitable for various Portland cements, but cannot be used for alumina cement.
3. This product can be directly mixed into cement or poured into a mixer to mix and then add water to wet mix.
5. Packaging and storage:
This product is double-packed, with each bag weighing 50±0.25 kg. During transportation and storage, pay attention to prevent damage, moisture, and agglomeration</p
