Sampling and Testing Grout1 This standard is issued under the xed designation C; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A astm c1019 pdf free download in parentheses indicates the year of last reapproval. A superscript epsilon indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense. Grout for masonry is specied under Specication C Signicance and Use 3. Excess water must be removed from grout specimens in order to provide compressive strength test results more nearly indicative of the grout strength in the wall, astm c1019 pdf free download.
In this test method, molds are made from masonry units having the same absorption and moisture content characteristics as those being used in the construction. NOTE 2Test results of grout specimens taken from a wall should not be compared to test results obtained with this test method. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
Referenced Documents 2. Current edition approved Feb. Published March Originally approved in Last previous edition approved in as C DOI: Apparatus 4. The rod shall be a minimum length of 12 mm. NOTE 3Nonabsorbent blocks may be of plastic, wood, or other nonabsorbent material.
Certain species of wood contain sugars which. United States. No further reproductions authorized. C 11 tion as those being used in the construction. The surface of the unit in contact with the grout specimen shall not have been previously used to mold specimens. Place nonabsorbent blocks, cut to proper size and of the proper thickness or quantity, at the bottom of the space to achieve the necessary height of specimen.
See Fig. New lining material shall be used for each specimen. NOTE 6The lining, such as paper towel, is used to aid in stripping the grout specimen from the mold. Proper installation of the lining prevents irregularly sized specimens and varying test results, astm c1019 pdf free download. NOTE 1Front masonry unit stack not shown to allow view of specimen. NOTE 1Front masonry unit not shown to allow view of specimen.
In order to prevent this from occurring, new wooden blocks shall be soaked in limewater for 24 h, sealed with varnish or wax, or covered with an impermeable material prior to use. Soak in limewater for 24 h, seal with varnish or wax, or cover with an impermeable material prior to use. A nonabsorbant material of equivalent stiffness to the plywood is permitted. Test Specimens 5, astm c1019 pdf free download.
NOTE 4Frequency of sampling and age of test is to be determined by the specier of this test method and is usually found in the construction documents. Such approval shall be based on comparative testing of grout specimens constructed from molds as described in 6. Approval shall be limited to a single specimen shape, method of forming, masonry units used, and grout mix. A conversion factor based on comparative testing of a minimum of ten pairs of specimens shall be used to modify results astm c1019 pdf free download alternative methods.
NOTE 7Other methods of obtaining grout specimens and specimens of different geometry have been employed in grout testing, but are not described in this test method. Other methods used to obtain grout specimens include: drilling grout-lled cores of regular units; lling cores of masonry units specically manufactured to provide grout specimens; lling compartments in slotted corrugated cardboard boxes specically manufactured to provide grout specimens; and forming specimens from different sized masonry units of the same or similar material.
Since test results vary with methods of forming the specimen, specimen geometry, astm c1019 pdf free download, and grout mix, comparative test results between specimens made with molds described in 6. Sampling Grout 7. After the nal slump adjustment has been made, sample grout as the grout is being placed. The elapsed time between obtaining the rst and nal portions of the sample shall be not more than 15 min.
Grout Specimen Molds 6. NOTE 5The location of specimen construction should be protected and as free from perceptible vibration as possible. If the grout is placed between two different types of masonry units, both types shall be used to construct the mold, astm c1019 pdf free download. Equivalent certication programs should include both written and performance examinations. Distribute the strokes uniformly over the cross section of the mold. Cover immediately with a damp absorbent material such as cloth or paper towel.
Keep the top surface of the specimens damp by wetting the absorbent material and covering with a nonabsorbent, nonreactive material to retain the moisture. Do not disturb the specimens. Strike off the top surface of the specimen with a straightedge to produce a at surface that is even with the top edge of the mold. Keep the top astm c1019 pdf free download of the specimen damp by wetting the absorbent material and covering with a nonabsorbent, nonreactive material.
Do not disturb the specimen until the molds are removed. NOTE 9The viscosity of self-consolidating grout changes with time. Thus the depression may require lling prior to the thirty minute limit. Transport the grout sample to the mold location. Remix the sample with a shovel or trowel to ensure uniformity prior to lling molds. Keep remaining grout sample protected until used to ll any depression in the sample due to astm c1019 pdf free download water loss.
Temperature and Slump Test 8. Compressive Test Specimen 9. Begin lling the compressive strength molds within 15 min of obtaining the nal portion of the sample.
Astm c1019 pdf free download each layer 15 times with the tamping rod. Rod the bottom layer through its depth. Slightly overll the mold.
Rod the second layer with the tamping rod penetrating 12 in. Store an indicating maximum-minimum thermometer with the specimens and record the maximum and minimum temperatures experienced prior to the time the specimens are placed in the nal curing environment.
Transportation, Curing, astm c1019 pdf free download, and Testing of the Specimens C 11 NOTE 11Various conditions, such as the use of set retarders or low ambient temperatures, may necessitate delaying mold removal until well after 24 h. Care should be taken to ensure the specimens have achieved sufficient strength for transportation, which may include delaying mold removal and transportation until 48 h.
Store there until day of testing. Keep specimen damp until tested. NOTE 12Practice C refers to capping cylindrical specimens; therefore, the alignment devices may need to be modied to ensure proper use with the rectangular prism specimens of this method. All other sections of Practice C are applicable. Measure and record the height of each face at midwidth.
Measure and record the amount out of plumb at mid-width of each face. Calculations Calculate the average corrected compressive strength by dividing the maximum load by the average cross-sectional area and multiplying the result by the conversion factor. Express the result to the nearest 10 psi 50 kPa. NOTE 13The coefficient of variation of test results of specimens formed by the alternative method should be less than or equal to that of the specimens formed in accordance with 6.
Precision and Bias Thus the standard deviation for this test method is higher than when using a nonabsorbent mold, astm c1019 pdf free download. Report C 11 There is less control of grout ingredients, conditions of the molds, and initial curing environment in eld-prepared specimens. The reproducibility of the procedure in Test Method C for measuring compressive strength is being determined and will be available on or before December It is not feasible to specify the reproducibility of the procedure at this time because of the variables in specimen preparation and curing.
A more detailed statement will be provided later. The following summary of available data is provided for review, astm c1019 pdf free download. Astm c1019 pdf free download standard deviations for those values were Additional tests on laboratory specimens had the characteristics found in Table 1. Keywords Approved Feb.
Committee C12 has identied the location of selected changes to this standard since the last issue C 08a that may impact the use of this standard. Approved Jan.
