aggregates have a linear expansion listed in Bulletin 14 greater than 0.10%: • Slag Cement, Grade 100 or 120, 25% min. • Flyash (Type F or Type C**) 15% min. (for flyash minimum cement content equal to 580 pounds per cubic yard. **Type C may be used provided alkali –silica reaction (ASR) is mitigated using additional Supplementary Cementitious Materials. • Silica Fume 5% - 10% • The total substitution of Portland cement must not exceed 50%, including the amount in the blended cement.
segregation testing performed during mixture qualifications does not exceed 9%. The requirement for meeting established Section 703 gradations do not apply if an optimized aggregate gradation is submitted and approved during the mix design qualification phase and controlled/verified during production according to an approved QC plan.
the slump flow test is less than the lower limit, reject SCC unless approved for vibration and is vibrated.

Method B and as indicated. Provide a sufficient quantity of thermal wires as indicated. If not indicated, provide quantity of thermal wires to achieve a distribution of one embedded thermal sensor for every foot of caisson diameter, with a minimum of four embedded thermal sensors, extending the full length of each drilled caisson. Provide wire length sufficient to be attached to readout boxes upon completion of concrete placement. Provide connection supplies and necessary splices. Provide suffici ent data loggers to maintain readings on each thermal wire for 96 hours from the completion concrete placement . Provide and mainta
