QUESTIONS WITH CORRECT
ANSWERS GRADED A+
◍ Does not provide additional strength, but it does improve mortar plasticity,
water retention, water tightness, and bonding ability..
Answer: Lime
◍ What ASTM is the standard spec for masonry cement.
Answer: ASTM C 91
◍ What ASTM is the standard spec for mortar cement.
Answer: ASTM C 1329
◍ High strength mortar recommended for use in reinforced masonry below
grade or in contact with the earth, as foundation and retaining walls subject
to high lateral or compressive loads; compressive strength is 2500 psi.
Answer: Type M mortar

sometimes used for repair. Generally limited to interior non-loadbearing
applications..
Answer: Type O mortar

strength are more important than compressive strength; compressive
strength is 1800 psi.

area of the grout space.
Answer: area of vertical reinforcement shall not exceed 6 percent of the area
of grout space

__________ apart..
Answer: 6.1.3.3 groups of parallel reinforcing bars bundled in contact to act
as a unit shall be limited to two in any one bundle. individual bats in a
