Summary of Test Method4.1 Polymer machinery grout of a flowable consistency ispoured into a hopper at one end of
7、a shallow plastic trough witha clear plastic cover plate.4.2 A movable gate is raised, allowing the grout to flowfrom the hopper into the trough. The times for the grout to firstcontact the end plate and to establish full length contact withthe top cover plate are recorded and used as indices offlow

The top surface of the grout is wire brushed to exposeany surface air bubbles or voids, and a visual estimate is madeof the percentage of grout top surface area that is in contactwith the plate.

Significance and Use5.1 Chemical-resistant polymer machinery grouts are usedto provide precision support for machinery or equipment.5.2 The machinery or equipment or support bases or plates,or combination thereof, are positioned to the precise elevationan
10、d location required. The bases or plates are typically placedon prepared foundations and supported on temporary shims orsupport bolts (jack screws). Forms are installed to contain theflowable grout. The grout is poured around the perimeter insuch a manner as to allow the grout to flow around and und

The grout subsequently hardensto provide a strong rigid support layer capable of withstandingthe stresses transferred by the equipment to the foundation.5.3 In addition to the required physical properties of thegrout, the flow and bearing area achieved are importantco

Apparatus6.1 Flow Box, a plastic flow box as shown in Fig. 3 withdemountable sides and ends and a sliding gate, having atransparent cover plate of rigid polycarbonate plastic.6.2 Stopwatch,
18、of normal commercial accuracy, readable toat least 1 s.6.3 Thermometer or Thermocouple , suitable for insertioninto the grout while still plastic.6.4 Mixer, a commercial mixing device that is able to rotatea 5-gal metal or plastic pail with a stationary mixing blade tostir the grout mix. Typical ope
19、rating speed is 30 to 100 rpm(see Fig. 4).7. Preparation of Apparatus7.1 Prewax all the component parts of the flow box withpaste wax and buff before assembly to ensure that the groutdoes not adhere. The top cover plate shall not be waxed sincethe wax may have an adverse effect on the bearing area.7
20、.2 Assemble the box as follows:7.2.1 Place the bottom plate on a flat work surface with thegrooves facing upward.7.2.2 Insert the left and right side plates of the box into thebottom plate with the grooved sides facing inward.7.2.3 Slide the back plate down between the slanted groovesof the left and
21、 right side plates at the headbox end such that itenters the cross groove in the bottom plate.7.2.4 Slide the gate plate into the vertical grooves in thefront of the headbox such that it rests directly on the bottomplate.FIG. 1 Grout Top SurfaceFIG. 2 Grout Top SurfaceC1339 02 (2012)27.2.5 Slide the
22、 cover plate in horizontally in the 2-in. (or1-in.) high slots in the side plates from the flow end of the boxuntil it contacts the gate plate firmly.7.2.6 Slide the front plate down along the gate plate on theoutside of the headbox until it contacts the cover plate.7.2.7 Slide the end plate down th
23、e end vertical grooves sothat it seals against the bottom plate.7.2.8 Slide the head plate down the groove 6 in. from theend plate so that it contacts the cover plate.7.2.9 Apply bands or clamps around the assembled box atthree locations snugly to resist the hydrostatic force of thegrout; one near t
24、he top of the headbox, one at midsection, andone between the head plate and end plate.7.3 Set the flow box on a flat level surface free from sourcesof vibration. Level the surface within 0.125 in. (3 mm) over thelength of the flow box.8. Conditioning8.1 Store the flow box, mixer, components of grout
25、, andother equipment at a temperature of 73 6 4F (23 6 2C) forat least 16 h prior to performing the test.8.2 The test may be performed at higher or lower tempera-tures to simulate specific installation conditions. If this is done,the temperature should be specified in the report.9. Procedure9.1 Mix
26、the grout following the manufacturers mixinginstructions. For 2-in. (5-cm) thickness, mix at least 600 in.3(9800 cm3) of the grout. For 1-in. (2.5-cm) thickness, mix atleast 400 in.3(6500 cm3) of the grout. Record the mixer typeand mixing speed.9.1.1 The revolving bucket type mixer referenced in 6.4
27、 isrecommended for mixing grout materials in the amount re-quired for this test. Large mixers are not recommended for thetest since the grout may become unrepresentatively aggregate-rich due to the wetting of the mixer by the liquid components.9.2 Immediately after mixing, measure and record thetemp
28、erature of the mix to the nearest 1F (0.5C).9.3 Pour the mixed grout into the hopper to an 11-in.(28-cm) depth for 2-in. thickness or 8 in. (20 cm) for 1-in.thickness.9.4 Five minutes from the time of completion of mixing thegate should be lifted past the junction of the front plate andcover plate i
29、n a smooth fast motion to allow the grout to flowinto the box.9.5 The stopwatch should be started at the moment the gateis lifted.9.6 Monitor the grout flow through the top cover plate as thegrout progresses down the box length. Record the elapsed timeat which the grout first makes contact with the
30、end plate as theflow time.9.7 Record the elapsed time at which the grout makes fulllength contact with the top cover plate as the fill time.9.8 Leave the filled flow box to cure undisturbed withoutmovement or vibration.9.9 At least 16 h after the time of pour, disassemble themold and remove the top
31、cover plate. Wire brush the grout topsurface to expose air bubbles and voids trapped at the groutsurface. Visually estimate the percentage of contact area andrecord as bearing area.9.9.1 Because of the limited accuracy of this determination,the suggested classifications are: “highgreater than 85 %,”
32、“medium70 to 85 %,” “lowless than 70 %.”10. Interpretation of Results10.1 For the purposes of this test, the elapsed time inseconds for the grout to flow to the end plate and the time tomake full length contact with the top cover plate are indices offlowability; the shorter the time, the greater the
33、 flowability.10.2 This test method is a simulation of applications wherethe flow distance is approximately 30 in. (75 cm), but actualapplication flow times may be longer because of the greaterroughness and porosity of a prepared concrete surface.10.3 The bearing area is useful in comparing grouts or
34、evaluating effects of different application temperatures.FIG. 3 Grout Flow BoxC1339 02 (2012)311.
