This test method provides a measure of the consistency and workability of fiber-reinforced concrete. The inverted slump-cone time is a better indicator than slump of the appropriate level of workability for fiber-reinforced concrete placed by vibration because such concrete can exhibit very low slump due to the presence of the fibers and still be easily consolidated. Mixtures with a time of flow less than 8 s, or with a slump greater than 2 in. (50 mm) shall be evaluated in terms of slump because the time of flow is too short to determine with satisfactory precision, or may not be determinable because the fiber-reinforced concrete flows freely through the inverted cone. The results may be used for mixture proportioning, quality control both in the laboratory and in the field, and in development and research. The results obtained using this test method may be influenced by vibrator diameter, amplitude, and frequency. This test method may not be applicable to some concretes reinforced with fibers flexible and long enough to wrap around the vibrating element and dampen vibration.1.1 This test method covers the determination of the inverted slump-cone time of fiber-reinforced concrete, both in the laboratory and in the field. 1.2 This test method is considered applicable to freshly mixed concrete having coarse aggregate up to 1 1/2 in. (38 mm) in size. It is not applicable to concrete that flows freely through the cone. 1.3 The values stated in inch-pound units are to be regarded as the standard. SI units are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 The electrical conductivity of concrete is primarily influenced by the presence of moisture. Other factors, which affect the electrical continuity of concrete structures, include the following:5.1.1 Presence of metal rebars,5.1.2 Cement content and type,5.1.3 Aggregate types,5.1.4 Admixtures,5.1.5 Porosity within the concrete,5.1.6 Above or below grade elevation,5.1.7 Indoor or outdoor location,5.1.8 Temperature and humidity, and5.1.9 Age of concrete.5.2 The electrical conductivity of concrete itself may be successfully used for high-voltage continuity testing of linings applied directly with no specific conductive underlayment installed. However, the voltage required to find a discontinuity may vary greatly from point to point on the structure. This variance may reduce the test reliability.5.3 Although the most common conductive underlayments are liquid primers applied by trowel, roller, or spray, and which contain carbon or graphite fillers, others may take the form of the following:5.3.1 Sheet-applied graphite veils,5.3.2 Conductive polymers,5.3.3 Conductive graphite fibers,5.3.4 Conductive metallic fibers, and5.3.5 Conductive metallic screening.5.4 Liquid-applied conductive underlayments may be desirable as they can serve to address imperfections in the concrete surface and provide a better base for which to apply the lining.5.5 This practice is intended for use only with new linings applied to concrete substrates. Inspecting a lining previously exposed to an immersion condition could result in damaging the lining or produce an erroneous detection of discontinuities due to permeation or moisture absorption of the lining. Deposits may also be present on the surface causing telegraphing. The use of a high voltage tester on a previously exposed lining is not recommended because of possible spark through which will damage an otherwise sound lining. A low voltage tester can be used but could produce erroneous readings.5.6 The user may consider this practice when performance requirements of the lining in a specified chemical environment require assurance of a lining free of discontinuities.5.7 Factors affecting the dielectric properties and test voltage shall be considered. Some factors are the curing time of liquid-applied linings; the possible presence of electrically conductive fillers or solvents, or both; the possible presence of air inclusions or voids; and the compatibility of conductive underlayments with the specified lining.5.8 A pulsed dc high voltage may cause a lining to breakdown at a lower voltage than would be the case for a continuous dc voltage.1.1 This practice covers procedures that may be used to allow the detection of discontinuities in nonconductive linings or other non-conductive coatings applied to concrete substrates.1.2 Discontinuities may include pinholes, internal voids, holidays, cracks, and conductive inclusions.1.3 This practice describes detection of discontinuities utilizing a high voltage spark tester using either pulsed or continuous dc voltage.NOTE 1: For further information on discontinuity testing refer to NACE Standard SP0188-2006 or Practice D5162.1.4 This practice describes procedures both with and without the use of a conductive underlayment.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 7.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
