Study Notes
Physical Properties of Materials
- Color, density, melting point, and boiling point are examples of physical properties.
Mechanical Properties of Materials
- Mechanical properties describe a material's response to applied forces.
- These properties include strength, stiffness, toughness, hardness, ductility, and brittleness.
- For example, tensile strength measures a material's resistance to breaking under tension.
Fire Resistance of Materials
- Fire resistance refers to a material's ability to withstand the effects of fire.
- This includes its ability to resist heat, flames, and the formation of toxic fumes.
Concrete and Fire
- Concrete loses strength when heated, and can crack and crumble if exposed to fire.
- Concrete's fire resistance is determined by its thickness, the presence of steel reinforcement, and its composition.
Cement Manufacturing
- The main raw materials for cement manufacturing are limestone, clay, silica, iron ore, and gypsum.
- These ingredients are crushed, ground, and then heated in a kiln to produce clinker, which is then mixed with gypsum to form cement.
Chemical Properties of Materials
- Chemical properties describe a material's behavior in chemical reactions.
- For example, the flammability of a material refers to its tendency to burn easily.
