MATERIALS TESTING Flashcards
Refers to measurement of the characteristics and
behavior of materials to be used in specifying the
suitability of materials to various applications.
Examination of materials properties with respect to
design and use of product.
MATERIALS TESTING
Categories of materials testing
- Mechanical Testing
- Testing for thermal properties
- Testing for electrical properties
- Testing for resistance to corrosion, radiation, and
biological deterioration - Non-destructive Testing
aims to find out properties of the materials such as the yield
strength or hardness, toughness where the materials are
physically tested to destruction.
MECHANICAL TESTING
ability to be stretched into a wire
DUCTILITY
ability to absorb energy and
plastically deform without fracturing.
TOUGHNESS
break easily or suddenly without any plastic
deformation first.
BRITTLENESS
measure of how easily a material can be
scratched or indented.
HARDNESS
the quality of being easily shaped or molded
PLASTICITY
ability of a material to return to its original
form.
ELASTICITY
Compressive and tensile strength.
STRENGTH
It is a method of testing a material’s ability to operate safely
at different temperatures.
TESTING FOR THERMAL PROPERTIES
refer to a material’s ability to conduct electric current
TESTING FOR ELECTRICAL PROPERTIES
Testing for breakdown or deterioration of materials under
exposure to a particular type of environment.
TESTING FOR RESISTANCE, CORROSION, RADIATION, AND BIOLOGICAL DETERIORATION
- It is a kind of testing and analysis technique used to
evaluate the properties of materials, components, structure
or system for characteristic differences or welding defects and
discontinuities without causing damage to the original part.
NON-DESTRUCTIVE TEST
An item, material or supply consumed or used in a
construction project and incorporated in the
constructed building or structure.
CONSTRUCTION MATERIAL
TYPES OF CONSTRUCTION MATERIALS
- BRICKS AND BRICKWORKS
- FERROUS AND NON-FERROUS METAL
- AGGREGATES
- BITUMENS
- CEMENT
- CONCRETE
were hand-mounded from moist clay and
then sunbaked, as is still the practice in certain arid climates.
The firing of clay bricks dates back well over 5000 years and is
now a sophisticated and highly controlled manufacturing
process.
BRICKS AND BRICKWOODS
any metal that contains iron, such as
stainless steel. They are known for their tensile strength,
which makes them ideal for architectural and structural uses
such as the tallest skyscrapers, as well as bridges, railways and
more.
FERROUS METAL
EXAMPLES OF FERROUS METALS
alloy steel, carbon steel, cast iron and wrought iron.
every metal and alloy that does not contain
iron.
NON-FERROUS METAL
EXAMPLE OF NON-FERROUS METAL
aluminum, copper, lead, nickel, tin, titanium, and zinc
is broad category coarse- to medium-grained particulate
material used in construction, including sand, gravel, crushed
stone, slag, recycled concrete and geosynthetic aggregates.
the most mined materials in the world.
AGGREGATES
refers to a substance produced through the distillation of
crude oil.
known for its waterproofing and adhesive properties and is commonly used in the construction
industry, notably for roads and highways.
BITUMEN
refers to materials which act as adhesives.
- is a binder, a chemical substance used for construction that
sets, hardens, and adheres to other materials to bind them
together.
CEMENT
- is a composite material composed of fine and coarse
aggregate bonded together with a fluid cement (cement
paste) that hardens cures over time.
CONCRETE
TESTS CARRIED OUT ON AGGREGATES
a) Sieve Analysis
b) Water Absorption
c) Aggregate Impact Value
d) Aggregate Abrasion Value
TESTS CARRIED OUT ON BITUMEN
a) Determining bitumen content
b) Determining flash and fire point of bitumen
c) Determining penetration of bitumen
d) Determining softening point of bitumen
e) Determining specific gravity of bitumen
f) Determining ductility of bitumen
TESTS CARRIED OUT ON CEMENT
a) Fineness Test
b) Soundness Test
c) Consistency Test
d) Setting Time Test
Test of Fresh Concrete
- Slump Test
- Compacting Factor Test
- VeBe Test

- Bend Test
- Re-bend Test
- Shear Test
- Brinell Hardness Test
- Impact Test
- Torsion Test
standards are formal, technical requirements that
establish quality specifications for a wide range of materials,
products, systems, and services; they serve as the basis for
manufacturing, procurement, and regulatory activities
worldwide.
ASTM (AMERICAN SOCIETY FOR TESTING MATERIALS)
Portland cement, used in making
concrete-are found throughout building codes and
construction specifications, where they are used as a
precise shorthand for describing the quality of
materials or the requirements of their installation
ASTM C150
is a nonprofit association that represents
highway and transportation departments across the nation.
works to educate the public and key decision makers
about the critical role that transportation plays in securing a
good quality of life and sound economy for our nation.
