1.01.3.1 The contractor will be required to provide a total of 1250 CY of concrete.

1.01.3.2 Concrete shall have a minimum of 5,000 PSI compressive strength as determined by the 28 day compressive strength test.

1.01.3.3 Concrete shall have a minimum flexural strength of 650 PSI.

1.01.3.4 Polypropylene synthetic fiber with a denier less than 100 and a nominal fiber length of 50 mm 2 inches will be added to the concrete for added resistance to plastic shrinkage cracking.

Fibermesh 150 synthetic fiber (or equivalent – with approval) will be added at a rate of 1.5 lbs per cubic yard. Please see the attached data sheet for Fibermesh 150.

1.01.3.12 Non-Conforming Materials: Factors that indicate that there are non-conforming materials include (but not limited to) excessive compressive strength, inadequate compressive strength, excessive slump, concrete delivery records that indicate excessive time between mixing and placement, or excessive water was added to the mixture during delivery and placement. Any of these indicators alone are sufficient reason for the Contracting Officer to request additional sampling and testing. Investigations into non-conforming materials must be conducted at the Contractor's expense. The Contractor must be responsible for the investigation and must make written recommendations to adequately mitigate or remediate the non-conforming material. The Contracting Officer may accept, accept with reduced payment, require mitigation, or require removal and replacement of non-conforming material at no additional cost to the Government.
