Plasticizing Accelerator
Obaproof QQ-Set is a water reducing plasticizing and accelerator admixture specially designed for concrete and mortar mix, Obaproof QQ-Set contains special reactive material and additives; it reduces the water cement ratio accelerates the cement hydration, reduces initial setting time, reduces shrinkage and improves workability, resulting in increase early strength of the concrete.
Direction for use:
1. Obaproof QQ-Set should dispersed in water before added to the
concrete or portland cement mortar mix.
2. Add Obaproof QQ-Set to the gauging water at the rate of 1000ml per 100kg portland cement mortar mix.
Advantages:
• Reduce initial setting time for rapid hardening
• Reduce cracking by minimize shrinkages
• Reduce water cement ratio
• Increase early strength of concrete
• Improve workability
Area of use:
Obaproof-QQ Set is used as high range water reducing agent for the production of very high early and ultimate strength concrete such as:
• Precast concrete elements
• Prestressed concrete
•Area of concrete where formwork must be removed quickly or early
loading is applied
Technical specification:
Appearance : Dark brown liquid
Specific gravity :1.25
Setting time :25-30% accelerated
Dosage:
Obaproof QQ-Set can be closed at the rate by 0.8- 1,0 litre per 100kg of cement depending on the workability and strength requirement. It is recommended that mixes to carried out to determine the accurate dosage rate required.
Dispensing:
Obaproof QQ-Set shall be dispensed neat into the premixed concrete after all the other concrete components, including total water, have been discharged into the pan-mixed or truck mixer. To obtain optimum concrete performance does not dilute Obaproof QQ-Set.
Shelf life and storage:
2 years from the date of production when stored in original unopened packaging in a cool dry place.
Safety precautions:
Wear gloves and goggles during application, If in contact with skin, wash throughly with soap and water. If in contact with eyes or mucous membrane, flush immediately with plenty of water and seek medical attention without delay.
