2.2.7 Underwater Large Mass Concrete

Limited to a washout less than 8.0 percent when tested in accordance with

COE CRD-C 61.

2.2.8 Alkali-Silica Reactivity Testing

Test all recommended concrete mixtures to determine the potential for alkali-silica reactivity of the mixtures in accordance with ASTM C1567.

Test results to have a measured expansion less than 0.10 percent at 16 days after casting.

If the recommended concrete mixture has ASTM C1567 test results higher than

0.10 percent at 16 calendar days, then additional tests are required to determine the source of the ASR, and will provide remedies to lower the potential for ASR. The final concrete mixture shall have expansion less than 0.10 percent at 16 calendar days when tested in accordance with

ASTM C1567.

2.2.9 Mass Concrete

Design to minimize temperature differential between the interior of the mass and the surface. The maximum Portland cement content is 400 and 450 pounds per cubic yard of concrete for Type I and Type II cements, respectively. All other requirements for concrete, including strength and W/C ratio, also apply. Curing methods, such as insulating the concrete, to be used to limit the temperature differential within the concrete mass.

2.2.9.1 Small Mass Concrete

The maximum Portland cement content to be 400 and 450 pounds per cubic yard of concrete for Type I and Type II cements, respectively. Supplementary cementitious materials, pozzolan, and ground granulated blast-furnace slag can be added in addition to the Portland cement limits.

2.2.9.2 Large Mass Concrete

Provide calculations showing the total internal concrete temperature (highest placement temperature and adiabatic temperature rise) does not exceed 150 degrees F. The calculations in accordance with ACI 207.2R.
