The machi

32、ne shall be provided with a flexure device in accordance with Figure A.3.4.1.1.4 Testing jig, the test requires the use of a jig in accordance with Figure A.4 to be incorporated in the lower platen; the upper platen receives the load from the compressive strength testing machine through an intermedi

33、ate spherical seating.4.1.2 Preparation of test unitsMould the specimens immediately after the mixing of the grout, with the mould firmly clamped to the jolting table. Introduce, using a suitable scoop, the first of two layers of grout into each of the compartments, directly from the mixing bowl. Sp

34、read the layer uniformly, then compact using 60 jolts. Introduce the second layer of grout, level, and compact with a further 60 jolts. Lift the mould gently from the jolting table, strike off excess of material, and smooth the surface with a flat trowel. Wipe off the grout left on the perimeter of

35、the mould. Place a 210 mm 185 mm plate glass sheet of 6 mm thickness on the mould. A plate of steel or other impermeable material of similar size can be used. Place the mould, suitably identified, on a horizontal base in standard conditions, (23 2) C and (50 5) % RH. After 24 h, carefully remove the

36、 specimen from the mould. Prepare three specimens for each grout. For fast-setting grout, demould the specimen immediately before the test.

After conditioning has been completed, place the prism in the testing machine (4.1.1.3) with one side face on the supporting rollers and with the longitudinal axis normal to the support. Apply the load vertically by means of the loa

38、ding roller to the opposite side face of the prism and increase it smoothly at the rate of (50 10) N/s until fracture. Keep the prism halves in standard conditions until tested in compression.4.1.4 Compressive strength under standard conditionsTest the prism halves broken in flexion, by means of the

39、 equipment specified in 4.1.1.4. Center the prism halves laterally to the platens of the machine within 0,5 mm, and longitudinally such that the end face of the prism overhangs the platens or auxiliary plates by about 10 mm.
