Summary of Test Method4.1 Arotating spindle is immersed in a container of catalysedcatalyzed chemical grout.An index to the viscosity is read directlyon the instrument scale.The test specimen viscosity is obtained from the dra

Significance and Use5.1 This test is intended for materials that will penetrate soil voids and rock fissures. Viscosity alone is not necessarily an exactindex of grout penetrability.NOTE 1The quality of the resu

Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objectivetesting/sampling/inspection/etc. Users o
21、f this standard are cautioned that compliance with of Practice D3740 does not in itself assure reliable results.Reliable results depend on mnay factors; of Practice D3740 provides a means of evaluating some of those factors.6.

ModelsLVF and LVT should be used for measurements above 20 cP (20 mPas), and for measurements from 1 to 20 cP (1 to 20 mPas)with the addition of a Model UL adapter. Models RV, RT, HA, and HB may be used for measurements above 100 cP (100 mPas).NOTE
23、 2The UL adapter may be used for better accuracy in the 20 to 100-cP (20 to 100-mPas) range also.6.2 Griffn Beaker, 600-cm3, low-form used as the container for the sample. Beaker material must not react with the grout. Glassbeakers are not acceptable for silicates. Stainless steel beakers are accept
