1Which construction activities fall within the scope of a Florida Certified Structural Masonry Specialty Contractor?
A.Load-bearing and reinforced masonry work using concrete masonry units, brick, and similar masonry elements
B.Wood frame and truss erection only
C.Sheet metal and gutter installation
D.Underground utility trenching and pipe installation
Explanation: The structural masonry specialty license covers masonry construction — load-bearing and reinforced walls, columns, piers, and similar elements built of CMU, brick, or block. The other trades listed (structural carpentry, sheet metal, underground utility) are separate CILB specialty licenses with their own trade exams.
2A candidate seeking Florida structural masonry certification must pass which set of examinations?
A.The Structural Masonry Trade Knowledge exam and the Business and Finance exam
B.Contract Administration and Project Management only
C.The trade exam alone
D.Business and Finance plus a separate Sign Specialty exam
Explanation: Division II certified specialty contractors (including structural masonry) must pass two exams: the trade knowledge exam specific to their specialty and the common Business and Finance exam. Contract Administration and Project Management are Division I (general/building/residential) requirements.
3What is the minimum experience generally required to qualify for the Florida Structural Masonry Specialty Contractor license?
A.Four years of structurally related experience, including at least one year as a foreman
B.Two years of any construction work
C.Four years exclusively in concrete finishing
D.One year as a laborer with no supervisory time
Explanation: Florida CILB specialty contractor qualification calls for four years of structurally related experience with at least one year spent in a foreman or supervisory role. The experience must relate to the structural masonry scope, not general labor or unrelated concrete finishing alone.
4What are the administration details of the Florida Structural Masonry Trade Knowledge examination?
A.55 scored questions, 2.5 hours, open-book, computer-based through Pearson VUE, 70% to pass
B.120 questions, 6.5 hours, closed-book
C.80 questions, 5 hours, open-book
D.55 questions, 2 hours, closed-book
Explanation: The structural masonry trade exam is a 55-question, 2.5-hour open-book CBT administered through Pearson VUE and Professional Testing, Inc.; a 70% score is required to pass. The 120-question, 6.5-hour exam is the Business and Finance portion, and the 80-question, 5-hour figure describes the Specialty Structure trade exam, a different license.
5Which ASTM C270 mortar type has the highest minimum compressive strength and is used for below-grade, heavy-load masonry?
A.Type M (2,500 psi)
B.Type S (1,800 psi)
C.Type N (750 psi)
D.Type O (350 psi)
Explanation: Type M mortar has the highest minimum compressive strength at 2,500 psi and is specified for below-grade, heavy-load-bearing masonry such as foundations and manholes. Type S (1,800 psi) is also strong but more commonly used for reinforced walls; Type N (750 psi) and Type O (350 psi) are above-grade and interior uses.
6What are the nominal dimensions of a standard full-length concrete masonry unit used in structural walls?
A.8 in x 8 in x 16 in
B.6 in x 8 in x 12 in
C.4 in x 4 in x 8 in
D.12 in x 12 in x 24 in
Explanation: A standard structural CMU is nominally 8 in thick, 8 in high, and 16 in long; the actual manufactured size is 7-5/8 x 7-5/8 x 15-5/8, with the 3/8 in mortar joint restoring the 8x8x16 module. This modular dimension is the basis for CMU estimating at 1.125 blocks per square foot.
7What distinguishes masonry cement from Portland cement as a mortar ingredient?
A.Masonry cement is a pre-blended mix of Portland cement, plasticizers, and air-entraining agents formulated for workability and water retention
B.Masonry cement is pure ground clinker with no additives
C.Masonry cement cures to a higher compressive strength than Portland cement
D.Masonry cement is used only in concrete, not mortar
Explanation: Masonry cement is a factory-blended product containing Portland cement plus lime, air-entraining, and water-retaining admixtures, designed to produce workable, bondable mortar when mixed with sand and water. Portland cement alone is pure hydraulic cement used in both concrete and mortar but requiring added lime for masonry use.
8Which ASTM standard governs load-bearing concrete masonry units?
A.ASTM C90
B.ASTM C91
C.ASTM C270
D.ASTM C144
Explanation: ASTM C90, Standard Specification for Loadbearing Concrete Masonry Units, sets the minimum compressive strength, absorption, and dimensional requirements for structural CMU. ASTM C270 covers mortar, ASTM C144 covers masonry sand, and ASTM C91 relates to masonry cement.
9How is coarse masonry grout distinguished from fine grout under ASTM C476?
A.Coarse grout includes both fine and coarse aggregate (up to 1/2 in), while fine grout uses only fine aggregate (up to 3/8 in)
B.Coarse grout has a lower slump than fine grout
C.Fine grout achieves higher compressive strength
D.Coarse grout is used only above grade
Explanation: ASTM C476 defines fine grout (maximum aggregate 3/8 in, fine aggregate only) and coarse grout (adds coarse aggregate up to 1/2 in). Coarse grout is generally preferred for larger cells because it is more economical, while fine grout is used where grout space or rebar congestion limits aggregate size. Both must meet the 2,000 psi minimum.
10What minimum compressive strength must masonry grout meet at 28 days per TMS 602 and ASTM C476?
A.2,000 psi, or equal to the specified masonry strength f'm when f'm exceeds 2,000 psi
B.1,000 psi in all cases
C.3,000 psi minimum regardless of design
D.2,500 psi, matching Type M mortar
Explanation: TMS 602 requires grout to reach at least 2,000 psi at 28 days; where the specified compressive strength of masonry f'm exceeds 2,000 psi, the grout strength must equal or exceed f'm. Grout is tested per ASTM C1019 and mixed to a high slump of 8 to 11 inches.

About the FL Structural Masonry Exam

The Florida Certified Structural Masonry trade knowledge exam covers structural masonry construction using concrete masonry units, brick, and block: masonry materials and units (CMU, brick, mortar types, grout, cement, admixtures), formwork and framework construction (forms, ties, bracing, tolerances, cold-weather protection), reinforcing steel placement (rebar grades, cover, lap splices, hooks, stirrups, dowels, ties), concrete and masonry techniques (mixing, laying, bond patterns, joint tooling, curing, grouting, hot and cold weather), structural elements (walls, columns, pilasters, lintels, shear walls, movement joints, flashing, cavity walls, retaining walls), building codes and standards (FBC Building/Residential/Existing Building, ACI 318, TMS 402/602, ASTM C90/C270/C476, plan reading), project management and estimation (Walker's Estimator's Reference Book takeoff, labor, material cost), and safety practices (OSHA 29 CFR 1926 wall bracing, scaffolding, silica, trench safety).

FL Structural Masonry Study Tips from Top Performers

1Build a content-to-book map: FBC Building and Residential for masonry provisions and wind requirements, TMS 402/602 for masonry code and grout, ACI 318 for reinforced concrete and cover, Placing Reinforcing Bars for lap and hooks, Walker's for estimating, and OSHA 1926 for safety.
2Practice tabbing by task (mortar types, grout pour heights, concrete cover tables, lap splice factors, control joint spacing, wall bracing heights, CMU count per 100 sq ft) rather than by chapter so you can find high-frequency lookups quickly under the roughly 2.7 minutes per question average.
3Drill the calculations: blocks per 100 sq ft (112.5), mortar bags per wall, grout cubic yards from cell volume, rebar count from spacing, lap length from bar diameter, course count from wall height, lintel triangular load, form contact area, and labor-hours from production rate.
4Learn the mortar and grout facts cold: ASTM C270 Type M 2500 / S 1800 / N 750 / O 350 psi, ASTM C476 grout minimum 2000 psi or f'm, grout slump 8 to 11 in, and fine versus coarse grout aggregate limits, since these drive both code and calculation questions.
5Use a two-pass strategy on test day: answer quick knowledge and easy lookup questions first, mark long calculations and uncertain code questions for review, and keep your reference setup identical to the one you trained with.
