ACCESSORY MATERIALS

Water: Clean and free from deleterious acids, alkalis, and organic matter.

Admixtures: Complying with ASTM C 1384.

PART 3 – EXECUTION

EXAMINATION

Examine surfaces to receive masonry work and conditions under which masonry will be installed.

Do not proceed with masonry work until surfaces and conditions comply with requirements indicated in referenced masonry installation standard and manufacturer's printed instructions.

INSTALLATION

Mixing: As recommended by manufacturer.

Re-tempering:

Re-temper grout by adding additional mixing water only to replace water lost due to evaporation.

Discard standard grout 1.5 hours after initial mixing.

Discard self-consolidating grout 30 minutes after initial mixing.

Installation of grout shall be as specified under the following Sections and in accordance with ACI/ASCE-530.1:

Section 04 20 00 - Unit Masonry

Section 04 21 00 - Clay Unit Masonry

Section 04 22 00 - Concrete Unit Masonry

Section 04 43 00 - Stone Masonry

Protection: Cover the top of unfinished masonry work to protect it from the weather and to prevent accumulation of water in the cores of the masonry units.

PROTECTION

Protect installed work from damage due to subsequent construction activity on the site.

FIELD QUALITY CONTROL

Tests:

Frequency: As determined by the Architect based upon total time for construction of masonry with not less than two tests per each level of masonry construction, foundation to roof or floors.

Testing Laboratory: Independent of the Owner, Architect and Contractor; the testing laboratory, in addition to meeting requirements of ASTM E-329, and must be an approved laboratory competent to perform cement physical testing. All tests must be performed in strict accordance with the applicable ASTM standard.

Distribution of Results of Tests: Within 24 hours of results of tests, copies of the results shall be submitted to the Architect, Contractor, masonry contractor, and the grout supplier if applicable.

Grout Testing:

Testing per ASTM C 1019.

Testing per ASTM C 1611.

Three test specimens shall constitute one sample. A strength test shall be the average of the strengths of the specimen tested at the age specified.

Specimens shall be tested at 7 and 28 days.

The compression strength will be considered satisfactory if the average of three consecutive tests of the grout is equal to or greater than the specified strength and no individual strength test falls below the specified strength by more than 500 psi.
