2、sion,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of long-termstrength and deformation of a cylindrical specimen
3、of either a(undisturbed)field sample or laboratory-fabricated chemicalgrouted soil when it is sheared undrained in compression undera constant sustained load.NOTE1The voids of chemical grouted soils are most often substan-tially filled with grout.Thus,pore pressures are unlikely to develop.Thistest
4、method is not applicable to partially grouted soils in which substantialpore pressures may develop.If pore pressures must be measured,reference is made to Test Method D4767 for equipment and procedures.1.2 This test method provides data useful in determiningstrength and deformation properties of che
5、mical grouted soilssubjected to sustained loads.Mohr strength envelopes may alsobe determined.1.3 The determination of strength envelopes and the devel-opment of relationships to aid in interpreting and evaluatingtest results are left to the engineer or office requesting the test.1.4 All observed an
