High Strength Concrete — What, why, how? –
The use of air entrainment in high strength concrete will greatly reduce the strength potential. More attention and evaluation will be necessary if the job specification sets limits for other concrete properties such as creep, shrinkage, and modulus of elasticity. The engineer may set limits on these properties for the design of the structure.
