3、method forsieve analysis of refractory materials.1.1.1 Wet Sieve AnalysisWater promotes the slaking ofclays and helps to separate fine particles,washing them fromthe larger grains.This method is recommended for use withmaterials that require water addition,and that slake in normalindustrial use.1.1.
4、2 Dry Sieve AnalysisThe dry method is not as effec-tive as the wet method in determining the amount of materialpresent in the smaller particle sizes.It is recommended(1)forclays,when the slaking action of water is undesirable,(2)whenthe material is in the form of coarsely ground grog and calcine,and
5、(3)when the clay is to be used in such a way that theultimate particle size is of secondary importance.1.2 These test methods also cover determination of thewater content of refractory materials in the wet condition andof air-dried samples as received,so that the sieve analysis canbe calculated on t
6、he dry basis.Included is a method forobtaining the water content of other refractory materials,suchas plastic refractories and wet mixes.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 f
