Organization: ASTM International
Publication Date: 10 June 2002
Status: inactive
Page Count: 6
ICS Code (Masonry): 91.080.30
scope:

1.1 These test methods cover procedures for the determination of the average in situ mortar joint shear strength index in existing unreinforced solid-unit and ungrouted hollow-unit masonry built with clay or concrete units. Three methods are provided:

1.1.1 Method A (with Flatjacks Controlling Normal Compressive Stress)-For determining mortar joint shear strength index when the state of normal compressive stress at the test site is controlled during the test using the flatjack method described in Test Method C 1197. Horizontal displacement of the test unit is monitored throughout the test. The test setup for Method A is shown in .

1.1.2 Method B (without Flatjacks Controlling Normal Compressive Stress)-For determining mortar joint shear strength index when using an estimate of the normal compressive stress at the location of the test site. Horizontal displacement of the test unit is not monitored during this procedure. The test set up for Method B is shown in .

1.1.3 Method C (with Flatjack Applying Horizontal Load)-For determining mortar joint shear strength index using an estimate of the normal compressive stress at the location of the test site, as shown in . Horizontal displacement of the test unit is generally not measured during this procedure.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
