Air entraining admixture, MNC-AE2, ASTM C260,
MNC-AE2 is an air entraining admixture which generates a highly
stable air void system for increased protection against damage from
freezing and thawing, severe weathering, or deicer chemicals.
MNC-AE2 is a light yellow powder product designed to generate
specification-quality air systems. Based on a high-grade saponified
formulation, MNC-AE2 is chemically similar to vinsolbased products,
but with increased purity and supply dependability. MNC-AE2
complies to ASTM C 260 Standard Specifications for Air-Entraining
Admixtures for Concrete.
MNC-AE2 air-entraining admixture may be used wherever the
purposeful entrainment of air is required by concrete
specifications. Formulated to perform across the entire spectrum of
production mixes, MNC-AE2 generates quality, freeze-thaw resistant
air systems in concrete conditions that include the following:
- Low Slump
- Central Mix
- Extruded Slip Form
- Mixes Containing Hot Water and Accelerators
- High Cement Factor
- Fly Ash and Slag
- Manufactured Sands

Light yellow powder
1.Increases the bond strength and avoid losing of concrete
compressive strength because of entrained air.
2.Preserves internal water and effectively reduces permeability
3.Enhances resistance to surface deterioration caused by de-icing
chemicals, sulfate attack and corrosive water.
4.Has more stable performance of anti-freezing/thawing compare with
other air entraining products.
5.Requires less mixing water used per cubic meter of concrete,
therefore bleeding is reduced.
6.Reduces bleeding and segregation of the concrete.
7.Be compatible with other admixtures.
8.Be non-toxic, non-flammable, and corrosion resistant.
9.Has high bonding strength, easier to be pumped and compacted.
Air is introduced into the concrete by the mechanics of mixing and
stabilized into millions of discrete semi-microscopic bubbles by
MNC-AE2. These air bubbles act much like flexible ball bearings
increasing the mobility, or plasticity and workability of the
concrete. This can permit a reduction in mixing water with no loss
of slump. Placeability is improved. Bleeding, plastic shrinkage and
segregation are minimized.
Through the purposeful entrainment of air, MNC-AE2 remarkably
increases the durability of concrete when exposed to severe
freezing and thawing. It has also demonstrated a remarkable ability
to resist the action of frost and deicing salts as well as sulfate,
sea and alkaline waters.
Testing or prior experience with the job materials and job
equipment is necessary to determine the proper dosage and minimum
mixing time. Recommended addition rate: Add 0.005- 0.015% for
mortar or concrete.
Package & Storage
