Significance and Use
5.2 The machinery or equipment or support bases or plates, or combination thereof, are positioned to the precise elevation and location required. The bases or plates are typically placed on prepared foundations and supported on temporary shims or support bolts (jack screws). Forms are installed to contain the flowable grout. The grout is poured around the perimeter in such a manner as to allow the grout to flow around and under the equipment base or plates. The grout subsequently hardens to provide a strong rigid support layer capable of withstanding the stresses transferred by the equipment to the foundation.
5.3 In addition to the required physical properties of the grout, the flow and bearing area achieved are important considerations for effective grout installation. The two characteristics measured by this test method are flow and bearing area.
5.4 The flow test simulates typical application conditions for a flowable polymer machinery grout. It may be used to evaluate the suitability of a particular grout for a specific application, to compare the flowability and bearing area of two or more grouts, or to evaluate the effects of formulation changes, temperature, mixing techniques, or other factors on flowability.
5.5 The estimated amount of upper grout surface contact in percent can be used to compare two or more grouts or show the effects of temperature, formulation changes, or other factors on bearing area. Because of the limited accuracy in estimating the percent of contact, a limited set of results is suggested (see 9.9.1). Visual guides are provided for comparative purposes (see Fig. 1 and Fig. 2).
1.1 This test method covers the measure of flowability of chemical-resistant polymer machinery grouts as evaluated in a 2-in. (5-cm) or 1-in. (2.5-cm) pour thickness. The test method provides 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 installations where grout thickness will range from 1 to 6 in. (2.5 to 15 cm) underneath the base or plates being grouted.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
