ADOAIR is a chemical formulation designed to impart the deliberate and controlled entrainment of air in concrete, in the form of disconnected, uniformly dispersed microscopic air bubbles.
It helps increase the workability with lower water/cement ratio. Offers increased resistance to passage of water through hardened concrete and produces frost resistant concrete.

Roads, Runways and Paving:
To obtain low water/cement ratio consistent with good placing and compaction properties. To reduce segregation and bleeding thus improving wearing properties and durability. To produce concrete resistant to the effects of freeze-thaw cycles. To speed placing and compaction. ADOAIR complies with the requirements of D.o.T. Specification for Highway Work Clause 1001.
Mass Concrete Structures:
To ease the placing of lean and under-sanded mixes and to reduce the excessive bleeding associated with these types of mixes. To provide improved water retention for curing throughout the mass.
Pneumatically Placed Concrete:
To ease the placing of lean harsh mixes. To prevent segregation a double dosage is recommended for this type of application, the excess air resulting from this will be expended during passage through the pipeline.
Concrete Block Making:
To ease de-moulding and reduce the number of breakages, and to improve surface texture and arises on the casting. There are numerous other applications where the inclusion of ADOAIR will produce concrete with all the benefits mentioned above.
Use:
The optimum amount of air to entrain is 3% to 6% and this is obtained by the addition of 20-60ml ADOAIR per 50Kg cement added to the gauging water or pre-wetted mix. The quantity of ADOAIR required to achieve the desired degree of air entrainment is dependent upon such factors as mix proportions, grading and shape of coarse and fine aggregates, water/cement ratio and temperature. To ensure that the desired degree of air entrainment is achieved we recommend that the air content be checked by means of an air meter.
Mix Design with ADOAIR
Commencing with an existing mix, check the degree of air entrained in the original concrete and proceed as follows:
for every 1% of additional entrained air required over the original, reduce the sand content by 4.5% of the cement content. Reduce total water content to give similar workability. This is generally achieved by a reduction of 10-20%

A typical example assuming 0.5% air entrained in the original mix and a required additional 4% air entrainment is as follows:

It can be seen that despite the entrainment of air the reduction in water/cement ratio combined with improved workability has produced a higher strength concrete with all the benefits obtained from controlled air entrainment It is also generally found that mixes redesigned in this manner show an increase in yield of 5-8% over the original mix, and this, combined with the saving in sand, more than compensates for the cost of ADOAIR.

Store in cool temperature, but above freezing, and stir just prior to use. In the event of freezing, material should be completely thawed and then thoroughly mixed before use.

12 months in sealed containers from date of manufacture.  Must be used 2 months after opening.
