Introduction:
This comprehensive practice exam is designed to prepare candidates for the California C-
29 Masonry Contractor license. It assesses the essential skills required to manage and
execute masonry projects, ranging from structural load-bearing walls to decorative veneer
applications. The questions follow a multiple-choice and scenario-based format, mirroring
the official state examination. Candidates will be tested on their ability to interpret
,blueprints, calculate material quantities, adhere to building codes, and maintain rigorous
safety standards. There is a strong emphasis on practical application, professional
decision-making, and the structural integrity of masonry systems within seismic zones.
SECTION 1: QUESTIONS 1–35
1. According to California Building Code, what is the standard thickness of a mortar
joint for concrete masonry units (CMU)?
A. 1/4 inch
🔴 B. 3/8 inch
C. 1/2 inch
D. 5/8 inch
🔵 Explanation: The standard industry and code-compliant thickness for both
vertical and horizontal mortar joints in CMU construction is 3/8 inch to allow for
dimensional coordination.
2. When estimating a masonry wall that is 100 feet long and 8 feet high using standard
8x8x16 CMU, approximately how many blocks are required (excluding waste)?
A. 800 blocks
🔴 B. 900 blocks
C. 1,125 blocks
, D. 1,200 blocks
🔵 Explanation: A standard 8x8x16 block covers 0.889 square feet. For an 800 sq.
ft. wall (100 x 8), the calculation is .889 = 900 blocks.
3. Which type of mortar is specifically recommended for reinforced masonry in high-
seismic regions like California?
A. Type N
B. Type O
🔴 C. Type S
D. Type K
🔵 Explanation: Type S mortar provides high lateral strength and is required for
structural reinforced masonry where high flexural bond strength is necessary.
4. What is the primary purpose of a "weep hole" in a brick veneer wall?
A. To provide ventilation for the insulation
🔴 B. To allow moisture drainage from the air cavity
C. To allow for thermal expansion of the brick
D. To provide an anchor point for wall ties
🔵 Explanation: Weep holes are placed in the bottom course of veneer to allow
water that has penetrated the brick or condensed in the cavity to exit the wall
system.
, 5. In masonry construction, what is "slump" a measure of?
A. The hardness of the cured grout
B. The weight of the masonry units
🔴 C. The consistency and flowability of the grout or concrete
D. The rate of water absorption in a brick
🔵 Explanation: A slump test measures the consistency and workability of grout to
ensure it can flow into small cavities and around rebar without segregating.
6. Which tool is most appropriate for finishing a concave mortar joint to ensure water
resistance?
🔴 A. Jointer
B. Hawk
C. Slicker
D. Pointing trowel
🔵 Explanation: A jointer (or sled runner) is used to compress the mortar into a
concave shape, which is the most effective joint for shedding water.
7. What is the maximum lift height for "low-lift" grouting in a CMU wall?
A. 2 feet
🔴 B. 5 feet
C. 8 feet
