False
Gypsum solid block is manufactured only with a 50mm (2’’) thickness.
True

False
Bronze is a rich golden-brown metal
True
Soldering is a method to join metals, to make electrical connections
True
Rivets are devices used to join or fasten the metals.
True
Cement paste is cement mix used to glue masonry units to each other.
False
A first binding coat is called sand coat
False
this method should not be used where a strong joint is required.
Soldering
a type of soldering in which the operating temperatures are higher (but lower than in welding)
Brazing
used for the reinforcement of concrete slabs and floors, as well as for stuccoed work
Wire fabric
used to reinforce concrete slabs used in light construction
Welded-wire mesh or welded-wire fabric
is the process by which two metals are so joined that there is an actual union of the interatomic bonds.
Welding
is a mortar of cementitious material ( lime, gypsum or cement), sand and water which is applied in coats.
Plaster
are hollow masonry units, open at two ends with interior webs or partitions 19mm (¾”) to 25mm (1”) dividing the block into longitudinal cells.
Structural clay tile
Should be placed into the piers, columns, slabs leaving 20 bar diameters exposed to splice with the reinforcement of the hollow blocks
Dowel bars
It usually consists of an aluminum alloy core of one type clad with another, highly corrosion-resistant aluminum roofing and siding.
Corrugated aluminum
This is a medium carbon steel with its carbon content controlled to give both the strength and ductility necessary for its use.
Structural steel
Usually deformed bars of varying grades and diameters.
Reinforcement of concrete
This is rigidized sheet fabricated from low-carbon cold or hot-rolled steel sheets which are either galvanized or covered with some type of bituminous coating.
Corrugated steel
is ductile, malleable, nonmagnetic metal with a characteristic bright, reddish brown color.
Copper
This is called the statuary bronze.
True bronze
It is nonmagnetic at ordinary temperatures but becomes magnetic at 13°F.
Chromium
It resembles iron in strength and toughness and copper in its resistance to oxidation and corrosion.
Nickel
They are used for concrete reinforcement, lath for plaster, stucco, and cement, fencing, insect screens.
Steel mesh and wire cloth
They are being increasingly used as reinforcing for pre-stressed concrete, high strength bolts, special structural steels and cables for elevators, etc.
High-strength low-alloy steel
It is highly resistant to corrosion by air and salt water.
Copper
Are highly alloyed steels that contain more than 10% chromium
Stainless steels
Is used for fine white lead paints, red lead litharge
Corroding lead
subject to galvanic action
Aluminum
On exposure it soon reacts to form a surface layer of an insoluble green salt.
Copper
Has the highest electrical and thermal conductivity of any substances
Copper
Is characterized by brittleness and low strength.
Zinc
Fundamentally an alloy of copper and zinc .
Brass
It is normally covered with a thin film of stannic oxide.
Tin
It is an alloy of copper and tin.
True bronze
Is a steel-white metal which takes a brilliant polish.
Chromium
Is a inert silvery metal.
Nickel
Is a blue-gray, soft, very heavy metal.
Lead
Is the most magnetically permeable of the metals
Pure Iron
Moderately high coefficient of expansion.
Aluminum
are structural units of clay or shale formed while plastic and
subsequently fired.
Bricks
Courses of stone face which
is jagged, so as to present a
rough surface.
Rustic or rock work
