CSLB B LICENSE GENERAL CONTRACTOR
ACTUAL EXAM QUESTIONS AND CORRECT
ANSWERS COMPLETE SOLUTION
●● Concrete Tool sequence
Answer: -Come-Along Rake: Rake used to pull and push concrete just
pumped out
-Screed Board (Straightedge): A long, perfectly straight board or metal
bar pulled
-Bull Float: A large, flat magnesium or aluminum blade on a long
extension pole
-Hand Mag Float (Magnesium Float)
Once its dried to finger test, Smooth top out.
Or Power Trowel (concrete helicopter)
The spinning pans smooth out high spots, fill in low spots, and bring up
the creamy cement paste.
-Trowel
Smooth out
Do not use excessive force
,-Concrete Edger: A small tool with a curved L-shaped lip.
-Groover (Jointer): A tool used to press straight lines into the concrete
slab at regular interval
-Broom: Drag a specialized stiff-bristled broom across the firm surface
●● Joint Spacing/depth
Answer: -Thickness times 2 for minimum spacing. Times 3 for
maximum spacing
-2 to 3 feet per inch of slab thickness
Depth is 1/4 of thickness
●● 4 joint types
Answer: -Construction Joints
When huge concrete pours have to be broken up. boundary between the
old, cured concrete and the fresh concrete poured later. Features like
interlocking keyways or steel dowel bars
-Control Joints
,Straight lines press with a groover, cut with a saw. Naturally cracks
weak spot. Hidden at the bottom of the groove instead of splintering
across the surface
-Expansion Joints
full-depth gaps between concrete slabs that contain filler material. Gets
hot, concrete expands. Filler absorb this movement. Stop buckle upward.
-Isolation joints
separate a concrete slab from any existing, immovable structures.
Different structures settle differently. This joint lets the slab move up
freely without damaging existing structures.
●● Cutting joint Rules
Answer: In hot climates within 12 hours of completion.
●● Curing times for Concrete
Answer: -2/4 hours initial set reached, no going bcak
-7 days for heavey objects
-28 full cure, heavy machinery
●● Sill Plate Rules
Answer: Foundation Grade Redwood, Preservative-Treated or Pressure-
Treated No. 2 or better
, Thickness: Min 2 inches. Must not be smaller than adjoining studs
Sill sealer thickness: 1/4
●● Anchor bolts rules
Answer: Hot-dipped galvanized
Minimum 2 bolts per plate
thickness: 1/2
Spacing: Max 6f, Min 1ft
Intendment: Min 7 inches
Ends: Max 1ft, Min 4inch
3 story or higher
5/8th inch anchor bolts
Wedge Anchors (Thunderstuds): You drill a hole, hammer the bolt in,
and tighten a nut.
-Flat Washer soft wood
-Split-Lock Washer machinery to stop a nut from vibrating loose.
DON'T USE: A lock washer
