Home My WebLink AboutS-347353STRUCTURAL CONCRETE MASONRY UNIT GENERAL NOTES 1. CONCRETE MASONRY UNITS: BLOCKS SHALL HAVE A LIGHTWEIGHT CLASSIFICATION AND CONFORM TO ASTM C90, LATEST EDITION. MINIMUM COMPRESSIVE STRENGTH OF UNITS OF 1,900 PSI WHEN AIR CURED FOR 28 -DAYS. MINIMUM COMPRESSIVE STRENGTH OF 1,500 PSI OF MASONRY WALL ASSEMBLAGE AT 28 -DAYS. 2. MORTAR: PROPORTION MORTAR TO CONFORM TO THE REQUIREMENTS OF ASTM C270 FOR TYPE S MORTAR. DO NOT USE MASONRY CEMENT. RETEMPER MORTAR ONLY BY ADDING WATER INTO THE MORTAR AND THEN WORKING WATER INTO THE MORTAR. RETEMPERING MORTAR BY DASHING WATER OVER THE MORTAR IS NOT PERMITTED. ANY MORTAR UNUSED WITHIN 2 1/2 HOURS OR GROUT THAT IS UNUSED WITHIN 1 1/2 HOURS AFTER INITIAL MIXING SHALL BE REMOVED FROM THE WORK. 3. GROUT: MINIMUM GROUT STRENGTH OF 2,500 PSI. INCREASE CEMENT CONTENT OF THE GROUT, AS NECESSARY TO ACHIEVE THE SPECIFIED MASONRY ASSEMBLY STRENGTH (fm) AND ADEQUATE WORKABILITY. GROUT COMPRESSIVE STRENGTH WHEN TESTED PER ASTM C1019 SHALL BE EQUAL OR EXCEED THE CONCRETE MASONRY UNIT STRENGTH. GROUT SHALL HAVE A SLUMP BETWEEN 9 AND 10- INCHES AT THE TIME OF PLACEMENT. ALL CELLS SHALL BE FILLED SOLIDLY WITH GROUT. ALL GROUT SHALL BE CONSOLIDATED BY MECHANICAL VIBRATION. 4. ADMIXTURES: ADMIXTURES ARE NOT PERMITTED IN MORTAR OR GROUT UNLESS FAVORABLY REVIEWED BY THE ENGINEER. 5. AGGREGATES: SAND FOR MORTAR SHALL CONFORM TO ASTM C144 EXCEPT NOT LESS THAN 3% OF THE SAND SHALL PASS THE NUMBER 100 SIEVE. SAND AND PEA GRAVEL FOR GROUT SHALL CONFORM TO ASTM C404, TABLE 1, COARSE AGGREGATE, EXCEPT WHEN OTHER GRADINGS ARE SPECIFICALLY APPROVED BY THE ENGINEER. 6. WATER: WATER USED FOR MORTAR AND GROUT SHALL BE CLEAN AND FREE FROM DELETERIOUS AMOUNTS OF ACIDS, SALTS, ALKALI, AND ORGANIC MATERIALS. 7. REINFORCEMENT: REINFORCING SHALL BE ASTM A615 -GRADE 60. REINFORCEMENT SHALL BE FULLY EMBEDDED IN GROUT. EMBEDDED ITEMS SHALL BE SECURED IN PLACE PRIOR TO GROUTING. PROVIDE A MINIMUM OF 1 -INCH GROUT AROUND BOLTS IN MASONRY. PLACE HORIZONTAL REINFORCING IN BOND BEAM UNITS. VERTICAL REINFORCING SHALL BE HELD IN PLACE AT TOP AND BOTTOM AND AT INTERVALS NOT EXCEEDING 200 BAR DIAMETERS. UTILIZE REBAR POSITIONERS TO ACHIEVE VERTICAL REINFORCING PLACEMENT. HORIZONTAL REINFORCING SHALL BE PLACED IN BOND BEAM UNITS, EXCEPT LINTEL UNITS SHALL BE USED OVER OPENINGS. 8. BEFORE PLACING BLOCK ON CONCRETE, CLEAN CONCRETE, ROUGHEN CONCRETE SO THAT AGGREGATE IS EXPOSED TO 1/4 -INCH AMPLITUDE AND APPLY BONDING AGENT. 9. LAY ALL MASONRY WITH COMMON OR RUNNING BOND. CONSTRUCT ALL MASONRY TO MAINTAIN AN UNOBSTRUCTED VERTICAL CONTINUITY OF THE CELLS TO BE FILLED. THE VERTICAL ALIGNMENT SHALL BE SUFFICIENT TO MAINTAIN A CLEAR, UNOBSTRUCTED VERTICAL FLUE IN ACCORDANCE WITH TABLE 7 OF THE SPECIFICATION FOR MASONRY IN ACI 530. 10. CONSTRUCTION JOINTS: WHEN GROUTING IS STOPPED FOR A PERIOD OF 1 HOUR OR LONGER, FORM HORIZONTAL CONSTRUCTION JOINTS BY STOPPING THE GROUT POUR 1 1/2 INCHES MINIMUM BELOW THE UPPER -MOST UNIT, EXCEPT AT THE TOP OF WALLS. 11. CONTROL JOINTS: LOCATE CONTROL JOINTS AS SHOWN ON PLANS OR AT 20' -0" MAXIMUM SPACING WHERE NOT SHOWN BUT NOT LESS THAN 2' -0" FROM A JAMB OR OPENING. PLACE LEDGER, LINTEL, OR TOP OF WALL BEAM REINFORCING CONTINUOUS THROUGH EXPANSION AND CONTROL JOINTS, WRAPPING BARS WITH 1/8 -INCH THICK BOND BREAKING TAPE 2' -0" BOTH SIDES OF JOINT. DO NOT SPLICE BOND BEAM REINFORCING WITHIN 6' -0" OF AN EXPANSION OR CONTROL JOINT. 12. SPECIAL INSPECTION: WHERE THE BUILDING, STRUCTURE OR STRUCTURAL ELEMENT REQUIRES SPECIAL INSPECTION AS NOTED ON THE PLANS AND THE REINFORCING SCHEDULE BELOW, PROVIDE SPECIAL INSPECTION IN ACCORDANCE WITH IBC CHAPTER 17. 13. INSPECTION: ALL WORK SHALL BE INSPECTED BY THE OWNER'S REPRESENTATIVE OR THE BUILDING OFFICIAL. THE CONTRACTOR SHALL MAINTAIN ALL WORK ACCESSIBLE AND EXPOSED FOR INSPECTION. INSPECTION SHALL INCLUDE BUT NOT BE LIMITED TO CHECKING CELLS FOR DEBRIS PRIOR TO GROUTING AND SIZE AND PLACEMENT OF REINFORCEMENT, ANCHORS, AND OTHER EMBEDDED ITEMS. SCHEDULE REINF SHALL APPLY IN ALL CASES UNLESS NOTED OTHERWISE ON SPECIFIC DETAILS OR SECTIONS.
