D.	Prior to pre-installation conference, prepare pre-construction trial mix or mixes, using proposed ingredients, be fabricated to ensure targeted engineering properties are met and the mix workability is within standard parameters. For fiber-reinforced concrete, prepare test specimens with the following modifications to ASTM C31/C31M:
1.	Prepare test specimens using external vibration (or rubber mallet) to consolidate the specimens. Do not use rodding since it may produce preferential fiber alignment and nonuniform fiber distribution that may cause variance in the results.

PART 3    EXECUTION
3.1	EXAMINATION

B.	Verify the concrete producer has allotted sufficient mixing time to ensure proper distribution of the Microsynthetic Fibers.
C.	Do not begin installation until substrates have been properly constructed and prepared as stated in the construction documents.
D.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
3.2	MIXING
A.	Follow manufacturer's recommendation for mixing fiber reinforcement in the concrete mixture.
B.	Fibers may be added to the concrete at any time before, during, or after the batching process except not at the same time as the cement.
C.	Microsynthetic fiber reinforcement shall be added at the addition rate specified by the project or structural engineer.
D.	Follow ASTM C-94, "Standard Specifications for Ready-Mixed Concrete," recommendations for mixing time and speed in assembling a homogeneous mix. Typically, 5-7 minutes (75-100 revolutions) of mixing at a high speed prior to pouring is recommended.
3.3	PLACING AND FINISHING
