2、year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This test method covers the determination of viscosityof catalysed chemical grouts with the Brookfield visco

3、meter(laboratory method), over the range from 1.0 to 1000 cP (0.001to 1 Pas).1.2 This standard does not purport to address all of thesafety problems, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determ

4、ine the applica-bility of regulatory limitations prior to use.1.3 This test method offers a set of instructions for perform-ing one or more specific operations.

8、efinitions of Terms Specific to This Standard:3.2.1 coeffcient of viscositythe ratio between the appliedshear stress and the rate of shear. This coefficient is a measureof the resistance to flow of the liquid. It is commonly called theviscosity of the liquid. The cgs unit of viscosity is 1 g/cms (1d

9、yn/s cm2) and is called a poise (P). Viscosities of thin liquidsare normally given in hundredths of a poise or centipoises (cP).The SI unit of viscosity is 1 Pas (1 Ns/m2) and is equal to 10P, or 1000 cP.3.2.2 Newtonian liquida liquid in which the shear stress isproportional to the rate of shearing

10、strain. This constant ratio isthe viscosity. Non-Newtonian behavior can be determined withthe Brookfield instrument by taking measurements at differentspindle speeds.4. Summary of Test Method4.1 A rotating spindle is immersed in a container of cataly-sed chemical grout.An index to the viscosity is r

11、ead directly onthe instrument scale.5. Significance and Use5.1 This test is intended for materials that will penetrate soilvoids and rock fissures. Viscosity alone is not necessarily anexact index of grout penetrability.NOTE 1The quality of the result produced by this test method isdependent on the

12、competence of the personnel performing it and thesuitability of the equipment and facilities used. Agencies that meet thecriteria of Practice D 3740 are generally considered capable of competentand objective testing/sampling/inspection/etc. Users of this standard arecautioned that compliance with of

13、 Practice D 3740 does not in itself assurereliable results. Reliable results depend on mnay factors; of PracticeD 3740 provides a means of evaluating some of those factors.6.

Beaker material must not react with the grout.Glass be

Stainless steelbeakers are acceptable for all materials.6.3 Calibrated Liquid-in-Glass Thermometers, accurate to61.0F (0.5C), or any other thermometric device of equalaccuracy.NOTE 3Glass thermometers should not be used with silicates.6.4 Temperature-Control B

Temperature rise due to chemi

It isdesirable to have such tests span the anticipated ground temperature.7.2 Viscosity data should be taken on catalysed groutsolution that contains all of the co

Instrument readings of viscosity(versus time) should be taken at approximately every twominutes.8.3.1 For materials whose gel time range is less than 10 min,a gel time s

25、hould be set between 50 and 100 % of gel timerange, and readings taken at least every 2 min or, if possible, at1-min intervals.8.3.2 For materials whose gel time range is over 30 min, agel time should be selected at least 25 % above minimum, andreadings taken at approximately equal time intervals to

26、 permitat least five readings prior to gelation.NOTE 7For materials whose normal setting time is modified byprolonged agitation (this includes many silicate and acrylamide grouts)only one reading per sample should be taken, and multiple samples usedto define the viscosity-time data.8.4 Insert the sp

If apparent viscosities differ bymore than 20 % at different spindle speeds, the grout shall bereported as non-Newtonian.NOTE 8For non-Newtonian fluids it is recommended that, wherepossible, sufficient readings be taken so that a chart of spindle speedversus “effective” viscosity may be re

Release theclutch and allow the dial to rotate until the pointer stabilizes.NOTE 9At speeds above 4 rpm, 20 to 30 s will generally be required.At slower speeds, it may take longer.9. Report9.1 The following data shall be included in the report:9.1
