1、Designation: C860 10Standard Test Method forDetermining the Consistency of Refractory Castable Usingthe Ball-In-Hand Test1This standard is issued under the fixed designation C860; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the
2、 year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method covers the
3、procedures for determiningthe consistency of a castable using the Ball-in-Hand Test. Theamount of water used in a castable has a significant influenceon its performance.1.2 This test method applies to regular weight castablerefractories and insulating castable refractories which aredescribed in Clas
4、sification C401. It also applies to suchcastables containing metal fibers.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This st
5、andard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of this standard to establish appropriate safetyand health practices and determine the applicability of regu-latory limitations prior to use.

Significance and Use3.1 This test method is used primarily to determine if afreshly mixed refractory castable is of the proper consistencyand therefore would most likely provide op
7、timum perfor-mance. It can also be used to estimate the correct wateraddition rate of a castable when either the manufacturersspecified water content is not available or when uniquecircumstances have rendered that recommendation unusable.3.2 The correct water content is an important factor thatmust
8、be controlled to obtain optimum castable performance.Excess water can reduce strength, increase volume shrinkage,and promote segregation of the castable ingredients. Insuffi-cient water can produce “honeycombs” (air voids) in thecastable because of the insufficient mobility during placementand in ex
9、treme cases can prevent the complete hydration of thecement (if used).3.3 The Ball-in-Hand test is subjective and somewhat de-pends on the skill of the operator. However, it is a universallyaccessible method due to the simplicity of the equipmentrequired, and it is readily used in the field.3.4 The
10、total wet mixing time of a castable influences therheological and final properties and therefore should be moni-tored.3.5 This test method can be performed in a laboratory or ona job site.3.6 This test method is not intended to determine the properconsistency for gunning applications, although it ma

Apparatus4.1 Castable MixerEither a manually or electrically op-erated mechanical mixer (see Fig. 1) may be used to preparebatches for consistency determination in a laboratory. Wetcastable may also be obtained while in the fi

Sampling5.1 A representative handful of freshly mixed castableshould be drawn from the center of the mixer while the mixeris not running.1This
