1. Materials in Construction
Ms. Ali
Introduction to Construction

2. AIM:
How do we identify and classify
construction materials?

3. Learning Objectives: At the end
of this lesson SWBAT:
•Identify different physical properties of
construction materials.
•Compare and contrast the difference between
ferrous and nonferrous materials.
•Describe Primary and Secondary processing.

4. NYS Standards: Content
Standard(s): Mathematics, Science,
and Technology.
Standard 1: Students will use mathematical analysis,
scientific inquiry, and engineering design, as
appropriate, to pose questions, seek answers, and
develop solutions.
Standard 2: Students will access, generate, process,
and transfer information using appropriate technologies.

5. Do Now:
In your notebooks, write down three
materials that was used in the construction
of this room.

6. What is the purpose of
construction materials?
 Every construction project is meant to
fulfill a specific purpose, in order for that
purpose to be fulfilled, there must be
materials.

7. Choosing Materials:
Choosing:
Classification
Best fit
Performance
Maintenance

8. Classification:
•Knowing how materials are classified will give
you better knowledge and understanding of
how they should be used.
•Materials can be classified into:
Solids
Liquids
Gas

9. Solids:
• The most common construction materials are solids.
Solids can be classified into 4 groups:
1. Polymers
2. Metals
3. Ceramics
4. Composites

10. Polymers:
•Two or more molecules combining through a chemical
reaction create polymers. There are two types of
polymers, natural and synthetic.
•Natural Polymers: wood, plants, starch, protein
•Synthetic Polymers: Plastic, nylon, polyester
Plastics:
Widely used
Inexpensive

11. Matals:
•Metals are classified into two types: ferrous and
nonferrous.
•Ferrous: Containing a large amount of iron.( e.g.
Steel)
•Nonferrous: Containing little to no iron. (e.g. tin,
coppers, aluminum)

12. Ceramics:
Ceramics are a great construction material because they
are formable and not greatly affected by chemicals, weather
or heat. (glass, stone, tile)
•Abundant
•Are made from silicates
•Inorganic with crystalline structure
•Unaffected by heat, weather or chemicals
•Insulators
•Inexpensive (raw material)
•Comprise many construction materials

13. Composites:
•Mixture of two or more materials bonded by
adhesive
•Can be made of any combination of natural and
synthetic materials
•Synthetic (finished product)
•Improve quality
•Replacement for natural materials
•Examples of composites: particleboard, plywood,
fiberboard.

14. Processing
Primary Processing:
•Processing of raw materials into standard sizes
(consistency).
•Obtained by harvesting, mining, and drilling.
Secondary Processing:
 Converting raw materials into usable industrial
materials.
Lumber, nails, pipes and fuel oils.

15. Summary:
1. What considerations should we have when
selecting construction materials?
2. What is the difference between Primary and
secondary Processing?
3. Compare and contrast Ferrous and Nonferrous
materials.
