5.2 Hardened Concrete Tests
5.2.1 Absorptivity, F-T, Compressive Strength, and Maturity Several standard hardened concrete tests were performed on all mixtures, as listed below:
• Absorptivity, (ASTM C1585 Standard Test Method for Measurement of Rate of Absorption of Water by Hydraulic-Cement Concretes).
• Freeze-thaw testing, (ASTM C666 Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing, Procedure B – freezing surrounded by air).
• Compressive strength at 3, 7, 14, 28, and 90 days, (ASTM C39 Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens).
The results from these tests are summarized in Tables 7-9. For the Phase III very low air content mixtures, the ASTM C666 F-T testing was expanded to also include freezing surrounded by water (Procedure A) and freezing surrounded by a 4.0 wt. % CaCl2 brine. The results from the three variations of ASTM C666 F-T test are listed in Table 10.
Maturity tests, (ASTM C1074 Standard Practice for Estimating Concrete Strength by the Maturity Method) were performed only on the Phase II high air content and low air content mixtures, as summarized in Tables 11 and 12. For all mixtures, Figures 20-24 show compressive strength gain plots, Figures 25-29 show absorptivity plots, and Figures 30-36 plot changes in the relative dynamic modulus of elasticity (RDME) during F-T testing. Figures 37-39 plot changes in weight during F-T testing for the Phase III very low air content mixtures.
5.2.2 Additional F-T Testing
After completion of the F-T testing on the Phase II concrete mixtures, beams from the following Phase II concrete mixtures were selected for additional F-T testing under several variations of the Procedure A regimen, i.e. freezing surrounded by water, freezing surrounded by a 4.0 wt. % (0.72 mol/L Cl-) CaCl2 brine, and freezing surrounded by a 4.2 wt. % (0.72 mol/L Cl-) NaCl brine:
• HI-VR-PC-6SK-45WC • HI-VR-PC-5SK-45WC • LO-VR-PC-6SK-45WC
• LO-VR-PC-5SK-45WC • LO-VR-PC-6SK-50WC • LO-VR-PC-5.5SK-52WC
Table 13 summarizes the results of the extended F-T testing.

Figure 29: Absorptivity plots for the Phase III very low air content 0.46 w/cm mixtures. From left to right, 564 lbs/yd3 CMC mixtures vs. 490 lbs/yd3 CMC mixtures. From top to bottom: straight portland cement mixtures, 40 wt. % substitution slag cement mixtures, and 25 wt. % substitution fly ash mixtures. Dashed lines denote mixtures with vinsol resin AEA; dotted lines denote mixtures with synthetic AEA.
