Lesson 1: Introduction Flashcards
(18 cards)
Construction Material and Testing deals with
•properties of common
construction materials
•examination of material
properties with respect to
design and use of end product
•design and control of aggregates,
concrete and asphalt mixtures,
principle of testing
•characteristics of test
•materials testing and equipment
Materials Engineer is responsible for
the
selection, specification,
and quality control of
materials
Classes of Criteria
•Economic Factors
•Mechanical Properties
Physical (Nonmechanical)
Properties
•Production/Construction Considerations
•Aesthetic Properties
•Sustainability
•Environmental Quality
Materials most frequently used
steel, aggregate, concrete,
masonry, asphalt, and wood
including soil
Material Advancement is the development of
better
quality, more
economical, and safer
materials
Material Advancement is commonly referred to as
high performance
materials
examples of high
performance materials
Polymers
▪ Adhesives
▪ Composites to
▪ Geotextiles
▪ Coatings
• cold formed metals
• Various synthetic products
• Super plasticizers
• Lightweight synthetic aggregates
• Fiber composite materials
PHYSICAL PROPERTIES defined as
properties that can be observed
or measured without changing
the composition of the material
Examples of physical properties
Porosity (n)
Void Ratio (e)
Water Absorption
Weathering Resistance
Water Permeability
Frost Resistance
Fire Resistance
Chemical Resistance
Durability
Mechanical properties defined as
properties that comprise a
response to the
applied load
Examples of mechanical properties
Strength
Compressive strength
Tensile strength
Flexural strength or bending strength
Impact Strength
Abrasion resistance
Hardness
Elasticity
Plasticity
Material behavior under stress
➢ ductility,
➢ brittleness,
➢ stiffness,
➢ flexibility,
➢ toughness,
➢ malleability and
➢ hardness
Material testing provide
Information about the tested materials prototypes or product samples
Why is material testing performed?
▪ Meeting requirements
of regulatory agencies
▪ Selecting appropriate
materials and treatments for
an application
▪ Evaluating product
design or improvement
specifications
▪ Verifying a construction/
production process
Types of Test Methods
- Non-Destructive
Materials Testing - Destructive Materials Testing
Other Testing Methods
Examples of Non-Destructive
Materials Testing
▪ Static and dynamic friction test
▪ Component testing
▪ Hardness test
