A+
A sample contains aggregate larger than that appropriate for the size of the moulds or
equipment. - Answer
It must be wet-sieved prior to testing
Air Content - Answer
The volume of air voids of plastic concrete, exclusive of pore space in aggregate
particles, determined through observations of the change of air volume in concrete with
a change in pressure.
Air Guage Dial - Answer
Permits direct reading to a minimum of 0.2% for air volumes in the usual range of 0-8%.
Air Meter Readings - Answer
Are to the nearest 0.1%.
Air Meter Rodding - Answer
15L - 25 strokes. Greater than 15L - 50 strokes.
Average specimen density - Answer
Should be 98-102% of the mix design plastic concrete density specified by the supplier.
Bearing Face Diameter 13mm greater than specimen? - Answer
Concentric circles no more than 0.8mm deep and not more than 1.2mm wide should be
inscribed to properly centre cylinder.
Bearing Surface Minimum Dimension - Answer
At least 3% greater than the specimen
Bearing Surfaces Should Not Depart from the plane... - Answer
More than 0.025mm. New blocks are manufactured at half that.
Bottom Bearing Block - Answer
At least 25mm thick when new, 22.5mm thick after resurfacing. Must be 3% greater
than specimen,
Calibration Cylinder - Answer
Volume in the range of 1-6% of the volume of the base container.
Capping Plate Temperature - Answer
20 to 30 degrees C.
Capping Recess/Mould - Answer
