ASTM C1579 − 13 Standard Test Method for Evaluating Plastic Shrinkage Cracking of Restrained Fiber Reinforced Concrete Using a Steel Form Insert

ASTM C1579 − 13 Standard Test Method for Evaluating Plastic Shrinkage Cracking of Restrained Fiber Reinforced Concrete Using a Steel Form Insert

Scope

1.1 This test method compares the surface cracking of fiber reinforced concrete panels with the surface cracking.

of control concrete panels subjected to prescribed conditions of restraint and moisture loss that are severe

enough to produce cracking before final setting of the concrete.

1.2 This test method can be used to compare the plastic shrinkage cracking behavior of different concrete.

mixtures containing fiber reinforcement.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Significance and Use
4.1 The test method is intended to evaluate the effects of evaporation, settlement, and early autogenous

shrinkage on the plastic shrinkage cracking performance of fiber reinforced concrete up to and for some hours

beyond the time of final setting (see Terminology C125).

4.2 The measured values obtained from this test may be used to compare the performance of concretes with

different mixture proportions, concretes with and without fibers, concretes containing various amounts of

different types of fibers,
