ACI Concrete Strength Testing Technician - Practice C1231/C1231M fully solved rated A+

ACI Concrete Strength Testing Technician - Practice C1231/C1231MSupplier, user - correct answer When qualification tests of unbounded pads are required, they are performed by the ______ or ______. False - correct answer This standard practice establishes a maximum number of pad reuses that may not be exceeded under any circumstances. True or False? 10 MPa (1500 psi), 80 MPa (12,000 psi) - correct answer Unbounded caps are not to be used for acceptance testing of concrete with compressive strength below _____ or above _____. False - correct answer Polyurethane or butyl pads with a Shore A durometer hardness of 50 that will be used on concrete with a compressive strength of 10 to 40 MPa (1500 and 6000 psi) need not be qualified prior to use. True or False? Date placed in service, pad durometer, number of uses - correct answer To keep track of pad usage, the user is required to maintain records that include: True - correct answer If a new neoprene pad with a Shore A durometer hardness of 50 is intended to test concrete cylinders with anticipated compressive strengths between 10 and 40 MPa (1500 to 6000 psi), it may be used "as is" from the manufacturer without further qualification testing. True or False? True - correct answer The term "unbonded cap" refers to the combination of a metal retainer and an elastomeric pad. True or False? True - correct answer Practice C1231/C1231M may be used instead of the capping requirements of Practice C617/C617M. True or False? True - correct answer The pads provide a uniform distribution of load from the bearing blocks of the testing machine by deforming in initial loading to conform to the contour of the ends of the cylinder. True or False?
