Unified Soil Classification System

A

The most widely used system for classifying soils. In this system, the soils are primarily classed as coarse-grained (gravels and sands), fine-grained (silts and clays), and highly organic.

Q

K-value

A

The thermal conductivity of a material.

20
Q

varnish

A

A clear coating consisting of resins dissolved in a volatile liquid. Varnish produces a hard, smooth, and glossy protective film.

21
Q

ram

A

The driving device of a hydraulic elevator, which is powered by liquid under pressure within a cylinder. Also referred to as a plunger.

22
Q

sheeting

A

Vertical members used to temporarily hold the face of an excavation during construction.

23
Q

safety glass

A

Laminated glass, consisting of a thin sheet of transparent plastic laminated between two layers of clear glass. Also referred to as shatterproof glass.

24
Q

cribbing

A

A cellular framework that is filled with rock or soil to retain an earth embankment.

25
Q

elastomeric flooring

A

Synthetic resins applied in liquid form, producing a durable, seamless floor surface.

26
Q

perm

A

The unit or permeability for a given material, expressing the resistance of the material to the penetration of moisture. One perm is equal to the flow of one grain of water vapor through one square foot of surface area per hour with a pressure difference of one inch of mercury.

27
Q

sound transmission class (STC)

A

A single-number rating for the evaluation of a particular cross-section in terms of it’s transmission of airborne sound. The higher the STC rating, the more effective the construction is at stopping airborne sound.

28
Q

check

A

A lengthwise separation of wood caused by nonuniform seasoning.

29
Q

selective-collective

A

An elevator operating system in which all calls are answered in the direction of a car’s travel, and calls in the opposite direction are ignored until the travel direction is reversed.

30
Q

terne plate

A

Steel coated with lead and tin, used for roofing and flashing.

31
Q

bronze

A

An alloy of copper and tin.

32
Q

base shoe

A

A quarter round trim piece used to cover the joint between the finish flooring and the base.

33
Q

carriage

A

An inclined timber beam that supports the steps of a wooden stairway.

34
Q

annealed glass

A

Ordinary window glass that has been cooled slowly to avoid locked in thermal stresses.

35
Q

bond

A

An arrangement of the elements of a masonry wall to provide strength by lapping the units. Also refers to the pattern formed by the exposed faces of the units.

36
Q

anodizing

A

A process of coating aluminum with a hard oxide film by electrolytic action to prevent corrosion and improve appearance.

37
Q

sand

A

Granular material, ranging from about 3/8” to 1/200”.

Q

unit lock

A

A preassembled lock that is installed quickly and efficiently in a rectangular notch cut in the door edge.

43
Q

head joint

A

The vertical mortar joint between ends of masonry units.

44
Q

edge-grained lumber

A

Lumber with rings at 45 degrees to 90 degrees with the wide face. Also called vertical-grained lumber.

45
Q

smelting

A

Extracting metal from it’s ore.

A

Tinted glass that absorbs a high percentage of solar radiation. Also referred to as actinic glass.

48
Q

Atterberg limits

A

The arbitrary limits which define the boundaries between the different states of rigidity or fluidity of fine-grained soils.
