3、fchemical-resistant polymer machinery grouts as evaluated in a2-in. (5-cm) or 1-in. (2.5-cm) pour thickness. The test methodprovides for the assessment of upper surface plate contact area(bearing area). These grouts will typically be two- or three-component formulations that may be used for installa
4、tionswhere grout thickness will range from 1 to 6 in. (2.5 to 15 cm)underneath the base or plates being grouted.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate saf

Summary of Test Method4.1 Polymer machinery grout of a flowable consistency ispoured into a hopper at one end of a shallow plastic trough witha clear plast
7、ic 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 offlowability.4.3 After the grout hardens, the m

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. Visual guides are provided for comparativepurposes (see Fig. 1 and Fig. 2).
9、5. 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 elevationand location required. The bases or plates a
10、re 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 underthe equipment base or plates. The grout
11、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 importantconsiderations for effective grout installat
12、ion. The two charac-teristics measured by this test method are flow and bearingarea.5.4 The flow test simulates typical application conditionsfor a flowable polymer machinery grout. It may be used toevaluate the suitability of a particular grout for a specificapplication, to compare the flowability
13、and bearing area of twoor more grouts, or to evaluate the effects of formulationchanges, temperature, mixing techniques, or other factors onflowability.1This test method is under the jurisdiction of ASTM Committee C03 onChemical-Resistant Nonmetallic Materials and is the direct responsibility ofSubc

15、59, United States.5.5 The estimated amount of upper grout surface contact inpercent can be used to compare two or more grouts or show theeffects of temperature, formulation changes, or other factors onbearing area. Because of the limited accuracy in estimating thepercent of contact, a limited set of
16、 results is suggested (see9.9.1). Visual guides are provided for comparative purposes(see Fig. 1 and Fig. 2).6. 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
17、, 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 op
18、erating 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.
19、7.2 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 an
20、d right side plates at the headbox end such that itenters the cross groove in the bottom plate.FIG. 1 Grout Top SurfaceFIG. 2 Grout Top SurfaceC133902e127.2.4 Slide the gate plate into the vertical grooves in thefront of the headbox such that it rests directly on the bottomplate.7.2.5 Slide the cove
21、r 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 the end
22、 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 the to
23、p 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, and
24、other 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 the g
25、rout 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 isre
26、commended 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 thetemperatu
27、re 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 in a s
28、mooth 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 end p
29、late 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 cover
30、 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 %,”“medi
31、um70 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 flow
32、ability.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 orevalu
33、ating effects of different application temperatures.11.
