Abstract:The effect of air entrainment on the compressive strength of high performance concrete is presented in this paper. Generally, an increase in the total air content of one percent decreases the compressive strength of concrete two to five percent. This rule of thumb was developed from research on normal strength concrete, but there is little data on the strength reduction due to entrained air in high performance concrete. The paper presents compressive strength test results of several high performance concrete mixtures with total air contents ranging from two to six percent. The compressive strength of the mixtures varied from 42.4 MPa (6150 psi) to 95.9 MPa (13,900 psi). The results of the study support the use of this rule of thumb for high performance concrete. Data are also presented on the increased dosage rate of air entraining agents required in low water to cementitious material ratio concrete.
