1. Materials in ConstructionMs. Ali Introduction to
Construction
2. AIM:How do we identify and classifyconstruction materials? 3.
Learning Objectives: At the endof this lesson SWBAT:Identify
different physical properties ofconstruction materials.Compare and
contrast the difference betweenferrous and nonferrous
materials.Describe Primary and Secondary processing. 4. NYS
Standards: ContentStandard(s): Mathematics, Science, and
Technology.Standard 1: Students will use mathematical
analysis,scientific inquiry, and engineering design, asappropriate,
to pose questions, seek answers, anddevelop solutions.Standard 2:
Students will access, generate, process,and transfer information
using appropriate technologies. 5. Do Now: In your notebooks, write
down threematerials that was used in the constructionof this room.
6. What is the purpose ofconstruction materials? Every construction
project is meant tofulfill a specific purpose, in order for
thatpurpose to be fulfilled, there must be materials. 7. Choosing
Materials:Choosing:ClassificationBest fitPerformanceMaintenance 8.
Classification:Knowing how materials are classified will giveyou
better knowledge and understanding ofhow 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. Polymers2. Metals3. Ceramics4.
Composites 10. Polymers:Two or more molecules combining through a
chemicalreaction create polymers. There are two types ofpolymers,
natural and synthetic.Natural Polymers: wood, plants, starch,
proteinSynthetic Polymers: Plastic, nylon, polyesterPlastics:
Widely used Inexpensive 11. Matals:Metals are classified into two
types: ferrous andnonferrous.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 theyare formable and not greatly
affected by chemicals, weatheror heat. (glass, stone,
tile)AbundantAre made from silicatesInorganic with crystalline
structureUnaffected by heat, weather or
chemicalsInsulatorsInexpensive (raw material)Comprise many
construction materials 13. Composites:Mixture of two or more
materials bonded byadhesiveCan be made of any combination of
natural andsynthetic materialsSynthetic (finished product)Improve
qualityReplacement for natural materialsExamples of composites:
particleboard, plywood,fiberboard. 14. ProcessingPrimary
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. 16. Homework: Due: Tomorrow!1. Finish your
crossword puzzles.2. Finish up your FlickR assignments!
