CMT module 1-2 Flashcards
These are group of materials that contains carbon as the basic element
and includes materials like timber, plastics, asphalt, bitumen, etc.
Organic Group
These are group of materials that contains the siliceous materials
essentially containing silica, calcareous and argillaceous materials like clay.
Some common building materials are metals: elements like iron, copper,
etc. and alloys of different elements.
Inorganic Group
These materials are categorized as solid in terms of physical form and
mostly they are used to bear loads such as stones, bricks, etc.
Solid Building Materials
These are materials that binds two or materials such as cement
(siliceous), lime (calcareous), clay (argillaceous), bitumen (organic), etc.
Binding Materials
These are materials that are used for decorative or finishing purposes
such as paint, varnish, distemper, etc.
Finishing Materials
These are materials used for insulation purposes such as rock wool,
glass wool, expanded clays, etc.
Insulating Materials
These materials are organic or ingenuous such as stones, timber,
metals, etc. which need only to be recovered and processed.
Naturally Occurring Material
These materials are made out from natural materials such as plastics,
concrete, mortars, etc.
Manufactured Material
are used to protect hands
against from possible injury by lifting
rough and heavy weight material,
scratching or abrasion or chemicals and
cold or heat.
Gloves
is used to protect the
eyes from particulates such as water
or chemicals from striking; and from
splitting fragments of sample
materials.
Safety goggle
is used
to protect the skin from
possible accidental spills
of chemicals.
Laboratory gown
are used to
determine the gradation or
particle distribution of aggregates
such as sand and gravel.
Set of Sieves
is used to
determine the moisture content or
water content of soils passing from
plastic to liquid state or condition.
Liquid Limit Device
is used
to determine the weight of a
sample or specimen.
Triple Beam Balance
is used to
determine the specific gravity of
liquids.
Blount Specific Gravity
is used
to determine the soundness of
cement.
Le Chatelier Apparatus
is used to
determine the setting time and
consistency of cement paste.
Vicat Apparatus
is
used to determine the setting
time and consistency of cement
paste.
Gilmore Needle Apparatus
are used
to determine the volume of
liquids.
Pycnometer Bottles
are used in the
preparation and molding of
concrete specimen.
