Heading: 1.2RE:Breaking Beams
Message:
On a recent job involving an Hanger ramp to the airstrip, the lab of record took 6x6x36 beams and will break half at 7 days and return the remainder in the cure tank and break the other half at 14 or 28 days. I looked in ASTM C 31 and could not find any reference one way or the other. Is this a proper proceedure?

Marc,

The Army Corp accepted 36" beams on the Fort Drum Project in the late 1980"s. I haven't seen this procedure for "double" breaking beams listed in ASTM. Look for technicians with strong backs as this size beam will weigh over 100 lbs. after the molds are stripped.
