questions and answers 100% correct
The test method of ASTM C39 consists of applying a compressive coaxial load to
molded cylinders or cores at any rate True or False? - correct answer False, a
prescribed rate
Results obtained from the compressive strength test method will depend on many
things, such as the size and ____ of the specimen, batching, _____ procedures, the age,
temperature and _____ conditions during curing. - correct answer Shape, mixing
moisture
This test method (ASTM C39) is used to determine ______ _____ of cylindrical specimens.
- correct answer Compressive strength
,The calibration of the testing machines must be verified under four conditions; within
_____ months of the last calibration, upon original installation or after _____, after
making _____ or adjustments, and whenever there is a reason to suspect the ____ of the
indicated loads. - correct answer 13, relocation, repairs, accuracy
The machine must be power operated and apply the load intermittently. True or False?
- correct answer False, apply the load continuously
Supplemental means of loading for calibration may be power or hand operated. True or
False? - correct answer True
The percentage of error for loads used in the testing machine should not exceed _____
of the indicated load. - correct answer ± 1.0%
, The testing machine should have two steel bearing blocks; a spherically seated block
and a solid block. True or False? - correct answer True
The _____ and _____ of the spherically seat bearing block must be designed so the steel
in the contact area doesn't permanently deform when loaded to the capacity of the
testing machine. - correct answer Ball, socket
The curved surface of the socket should be _____ and lubricated with ______ at least
every _____ months. - correct answer Clean, petroleum-type oil, six (or as specified by
the manufacturer of the test machine)
