Final answer:
The range of air entrainment of light weight moderate exposure structural concrete is 3 to 8.
Step-by-step explanation:
The range of air entrainment of light weight moderate exposure structural concrete is 3 to 8. This means that the air content in the concrete can range from 3% to 8% of the total volume of the concrete mixture. The air entrainment helps to improve the workability and durability of the concrete.
