2.05 CONCRETE MASONRY UNITS
A. STANDARD WEIGHT CONCRETE MASONRY UNITS
1. Conform to ASTM C90-01a, grade "N", Type II, 8" x 16" and 12” x 16” modular units, thickness
as indicated on the drawings, minimum 1" face shells. Units 8" or more thick must have
minimum 1 1/4" face shells. Aggregate is to be gravel, air-cooled blast furnace slag, or crushed
stone. Units are to be acceptable visually, structurally, and free from undesirable defects
resulting from either manufacturer or handling, as judged by ARCHITECT.
The design compressive strength of the masonry, f'm = 1500 psi minimum (1900 PSI on net
area).
2. Units which have not been subjected to an approved method of steam curing must be stored for
30 days prior to use.
3. Sound transmission loss through 4" unpainted unplastered wall, must not measure less than
36 decibels.
4. Linear drying shrinkage must not be greater than 0.04% when tested as prescribed by National
Bureau of Standards.
5. Moisture content at time of delivery must not exceed 75% of relative humidity, as measured by
approved methods of Portland Cement Association.
6. Standard brick sized units are to be solid, but otherwise conform to these paragraphs.
B. ACCESSORY UNITS
1. 8" x 16" x 8" thick header block at locations indicated.
2. 8" x 16" knock out cut-lintel units, thickness as indicated.
