RW Air Plus (Bubble Generator Additive)

Applications:
– Roads, Highways, Airport Runways, and Sidewalks: Ideal for concrete pouring in infrastructure projects.
– Dams and Reservoirs: Suitable for constructing durable concrete structures.
– Cold Storage Facilities and Docks: Perfect for environments requiring high resistance to temperature fluctuations.
– Cold Climate Regions: Ensures concrete durability in freezing conditions.
– Exposed Concrete Elements: Suitable for all exposed concrete components.
– Street and Highway Curbs: Enhances the durability of concrete curbs.
– Controlled Bleeding: Facilitates controlled bleeding of cement paste, reducing water and chemical permeability.
– Improved Flexural Strength: Enhances the bending strength of concrete.

Benefits:
– Enhanced Freeze-Thaw Resistance: Increases concrete’s resistance to freeze-thaw cycles.
– Improved Impermeability: Reduces water and chemical penetration, ensuring better waterproofing.
– Reduced Segregation and Bleeding: Minimizes the risk of concrete segregation and bleeding.
– Increased Workability: Enhances concrete slump and workability.
– Compatibility: Compatible with all types of admixtures, including plasticizers, superplasticizers, accelerators, retarders, waterproofing agents, and pozzolanic materials.
– Non-Corrosive: Free from chloride and nitrate, ensuring no harm to concrete or reinforcement.

Dosage:
The optimal air content in concrete should range between 3% to 6%. Factors such as cement type, water-cement ratio, ambient temperature, aggregate type, slump, and the use of fine materials like fly ash, bentonite, and microsilica significantly influence the dosage. Continuous on-site testing is essential. Typically, the dosage ranges from 0.1% to 0.5% of the cement weight, depending on the materials available and the type of cement used.

Note: In mix designs incorporating setting controllers like accelerators, retarders, or superplasticizers, the dosage of RW Air Plus may be reduced.

Application Methods:
1. Direct Addition to Mixing Water: Add RW Air Plus to the mixing water before introducing it to the dry concrete mix.
2. Addition to Fine, Moist Sand: Mix RW Air Plus with fine, moist sand before adding it to the other concrete components.

Important Notes:
– Mixing Time: According to ASTM C182, the mixing process should include 3 minutes of mixing, 3 minutes of rest, and a final 2 minutes of mixing.
– Multiple Admixtures: As per ACI 212, when using two or more admixtures simultaneously, each should be added separately to the mix and should not be pre-mixed before addition.
