COMPLETE SOLUTIONS.
True - (answer)T/F: Dry-press process uses IDRW porosity clays.
False - (answer)T/F: Column forms always require form ties.
False - (answer)T/F: Efflorescence may suddenly appear on masonry wall after it is built. This is an
indication of faulty construction.
True - (answer)T/F: Precast elements are sometimes joined together using gravity.
True - (answer)T/F: Bricks shrink considerably during drying and firing.
True - (answer)T/F: Concrete strength is specified by a compressive strength at 28 days.
False - (answer)T/F: Precast elements may be reinforced by pre-stressing or conventional reinforcing,
but never a combination of the two.
True - (answer)T/F: Insulating Concrete Forms become a permanent part of the structure.
False - (answer)T/F: Double T precast slabs are hard to handle due to their tipping issues.
True - (answer)T/F: A composite masonry wall is named because it features an outer wythe of stone or
brick and an interior wythe of CMU's.
False - (answer)T/F: The minimum recommended cavity depth is 2 feet.
True - (answer)T/F: Pre-stressing tensions the steel and places the concrete in compression, giving a
more efficient structural member.
True - (answer)T/F: Compared to site-cast concrete, pre-cast concrete erection is faster.

True - (answer)T/F: Mortar seals joints between the masonry units.
True - (answer)T/F: Stone masonry can be set/stacked without mortar.
True - (answer)T/F: Post tensioning reduces the necessary depth of a structure and helps reduce
cracking.

separate specific lengths.
Block-Outs - (answer)Openings formed and cast in concrete structures.
Haunch - (answer)A structural column component that provides direct support of a beam or slab
element.
- (answer)Pads that are inserted at points of precast concrete-to-concrete contact to avoid grinding at
these points of high stress.
Quicklime - (answer)Limestone and other minerals are finely ground and heated to produce calcium and
magnesium oxides
Igneous - (answer)Rock developed magma/volcanic eruption
Tunnel Kiln - (answer)Brick loads pass continuously from one into another.
Bull Float - (answer)Is drawn back and forth over the slab
Makes deep, long cuts into the solid rock - (answer)A long-bladed diamond saw, traveling on rails
Rowlock - (answer)Brick laid on its face, with end visible
Easier job site modification - (answer)Which of the following is NOT an advantage of pre-cast concrete?
This concrete isn't doing much work structurally anyway - (answer)A one-way concrete joint system can
be thought of as a very thick one-way slab with the concrete between the joints left out because...
