- Min width of concrete or masonry footings for poorly-graded sands soil with load-bearing value 2,000 psf and 4-in brick veneer over frame for 2 stories house?
16”.
- Min thicknes of slab-on-ground floors?
3-1/2”.
- Reinforcing mesh in slab?
Min 6x6 - 10X10 welded wire mesh between center. and upper third of slab secured in place during pour.
- A strip of plaster or other material placed on a surface as a guide to thickness?
Screed, (skrYd).
- Names of stucco coats?
- Scratch.
- Brown.
- Finish.
- Masonry veneer requirements?
- Flashing sloped to drain.
- Weep holes max 33 in. o.c.
- Min 1” air space.
- Metal ties max 24 “ o.c.
- Material other than water, aggregate, or hydraulic cement used as an ingredient of concrete and added to concrete before or during its mixing to modify its properties?
Admixture.
- Granual material such as sand, gravel, crushed stone, and iron blast-furnace slag, used with a cementing medium to form a hydraulic cement concrete or mortar?
Aggregate.
- Concrete containing microscopic air cells to relieve internal pressure on the concrete from expansion of water when it freezes.
Air-ietrained. Typical air-entrained concrete contains 5%- 8% of air by volume.
- For buildings with unbalanced basements, the ratio of length to width. For structural sheathing or reinforced CMU shear walls, the ratio of height to width of the braced wall?
Aspect ratio.
- A horizontal grouted element within masonry embedded with reinforcement?
Bond beam.
- Mixture of Portland cement or any other hydraulic cement, fine-aggregate, coarce aggregate, and water, with or without admixtures?
Concrete.
- Type of concrete?
Type 1 - it is normal Portland cement and is used in most residential construction.
Type 2 - it is used for structures in water or soil containing moderate amounts of sulfate or when heat buildup is a concern.
Type 3 - It is used when high early strength is desired. It is not common in single-family residential construction.
Type 4 - It is low heat Portland cement and is used when the amount and rate of heat generation must be kept to a minimum. It is not common in single-family residential construction.
Type 5 - It is sulfite resistant Portland cement and is used when the water or soil is high in alkali.
- A coating intended to protect against the passage of water vapor through walls or other building elements. It is a lesser degree of protection than waterproofing?
Damp proofing.
- Conditions requiring a set of plans and specifications created by a registered (licensed) design professional and beyond the prescriptive requirements of the IRC.
Design required.
- The finished ground level adjoining the building at all exterior walls?
Grade.
- Load produced by use and occupancy of the building and not including wind, snow, rain, earthquake, flood, or dead loads?
Live loads.
- Concrete cast in one continuous operation with no joints, such as a footing and floor slab, or a footing and foundation stem wall?
Monolithic.
- The unit of measurement of water vapor transmission through a material, based on the number of grains of water vapor at a given pressure differential?
Perms. Vapor retarders are rated in perms.
- Structural concrete with no reinforcement or with less reinforcement than the minimum amount specified for reinforced concrete?
Plain concrete.
- Common method of measuring concrete strength. Most common concrete come in 2,000, 2,500, 3,000, 3,500 and 4,000 psi strengths?
PSI, (pound per square inch).
- Classification assigned to buildings based on location and severity of earthquake ground motion expected at the site?
Seismic design category.
- A term for walls designed to resist racking and distortion from wind or seismic forces?
Shear wall.
- That portion of a building that is between the upper surface of one floor and below the upper surface of the next floor above or the roof?
Story.
- That part of the building which is more than 6 feet above grade for more than 50% of the total building perimeter or more than 2 feet above ground at any point?
Story above grade,
- A method of field measuring of the stiffness of fresh concrete usually performed with a cone shaped device?
Slump test. More water in the mix means higher slump and weaker concrete. Both the type of concrete ordered and psi will affect slump.
- Materials that protect walls or other building elements from the passage of moisture as either vapor or liquid under hydrostatic pressure?
Waterproofing.
