Equipment needed for capping process includes capping, Plates, alignment, melting
blank, blank devices, and blank pots
Plates for neat cement and high strength gypsum plaster cap Glass, metal, granite, diabase
should be made of blank, blank, blank or blank
Sulfur cap plate should be formed against blank or blank Metal, granite or diabase
plates
The purpose of the guidebar or bull's-eye level is to ensure True
the caps remaining perpendicular to the axis of the cylinder

Harden concrete cylinder should be capped with blank, High strength, Gyptian paste, cement paste, sulfur motor
blank, blank, or blank.
Plaster of pairs and mixtures of plaster of pairs and Portland False
cement are examples of suitable high strength plaster. True or
false
Sulfur, high strength Gypsum, cement cubes must demonstrate 5000 psi cylinder strength
a minimum expressive strength of blank or blank, whichever is
greater
, The cement paste should not be applied to the freshly 2 to 4, settling
molded cylinders for blank hours after molding. This is to allow
for blank of the concrete specimen.
Select all that apply the strength of most Neat cement paste A, B, D
depends on:
A. The water cement ratio.
B. Cure time, age of cap
c. Equipment used
D. Type of cement.
A slight twisting action will help eliminate blank and air blank Excessive paste, voids
when the capping plate is placed onto the mound of the neat
cement paste
Neat cement past cap should not be used on dry specimens Shrink, crack
because the caps may blank and blank when dry
The technician should remove all blank or blank materials from Oily, waxy
the end of the hard and concrete cylinders before Capping
Blank the pot and recharge the fresh material at intervals to Empty, five
ensure that the oldest material in the pot has not been used
more than blank times
When capping concrete cylinders with a compressor strength False

compound recovered from the capping operation or old cap.
True or false.
To avoid blank, the sulfur should be dry when it is added to Foaming, water.
