Air entraining, water reducing, viscosity modifying combination designed specifically for use with volumetric (auger style) mixers.
AIR ENTRAINING & WATER REDUCING ADMIXTURE FOR CONCRETE
Specco #1915 Auger Aid® is combination air entraining and water reducing admixture formulated primarily for mobile mix or continuous “auger” type concrete mixers. #1915 Auger Aid® complies with ASTM C-260 and AASHTO M-154 specifications for air entraining admixtures. #1915 Auger Aid® is viscosity modified for bleed water and segregation control, and contains a low range water reducer for increased compressive strength and durability of the cured concrete.
BENEFITS:
- Provides a stable air void system with uniform bubble size and spacing.
- Added freeze-thaw protection.
- Lower (w/c) water to cement ratio.
- Easier placement and finishing.
- Shrinkage control.
- Improved resistance to scaling from deicing salts.
COMPOSITION: Low viscosity modified lignosulfonate based solution. #1915 Auger Aid® does not contain any calcium chloride or intentionally added chlorides that would initiate or promote corrosion of reinforcement steel, or contribute to efflorescence.
DIRECTIONS FOR USE / RECOMMENDED ADDITION RATES: There is no set dosage rate for #1915 Auger Aid®; however, it is typically dosed at 8-16 ounces per 100 lbs. of cement (522-1045 ml/100 kg) for most applications to produce concrete with 4-8% air entrainment. The exact quantity of #1915 Auger Aid® required will vary due to differences in the concrete materials or pour field conditions. These include but are not limited to: ambient and mix temperatures, cement, sand and aggregate gradation and ratio, additional admixtures in the mix, slump, water content, and temperature, mix time and mixer type, means of conveying and placing, as well as vibration method and duration. Specco recommends a trial mix be conducted with actual production materials in order to determine the optimum dosage for specific set time or strength requirements. Once this dosage is established frequent checks should be made during the placement of the concrete to ensure desired air entrainment levels are maintained. The pre-measured amount of #1915 Auger Aid® selected should be added to the batch water if possible to allow maximum dispersion throughout the mix.
