Description
Characteristics & Advantages
• Reduce initial setting time for rapid hardening
• Reduce cracking by minimise shrinkages
• Reduce water-cement ratio
• Increase early strength of concrete
• Improve workability
Application Area
Obaproof QQ-Set is used as high range water-reducing agent for the production of ultimate strength concrete such as:
• Precast concrete elements
• Prestressed concrete
• Area of concrete where formwork must be removed quickly or early loading is applied
Pot Life / Shelf life
Shelf life: 2 years from the date of production when stored in original unopened packaging in a cool and dry place.
Uses
• Obaproof QQ-Set should disperse in water before adding to the concrete or Portland cement mortar mix.
• Add Obaproof QQ-Set to the gauging water at the rate of 1000ml / 100kg Portland cement mortar mix.
Application
Obaproof QQ-Set shall be dispensed neatly into the premixed concrete after all the other concrete components, including total water, to be discharged into the pan mixer or truck mixer. To obtain optimum concrete performance, do not dilute Obaproof QQ-Set.
Dosage
Obaproof QQ-Set has a sealing capacity of 0.8-1.0 liters per 100 kg of cement, depending on workability and strength requirements. Mixing is recommended to determine the exact dose rate required.
