Properties and Characteristics of Construction Materials - JSS2 Basic technology Lesson Note

Understanding the properties of construction materials is essential for their effective use:

• Concrete: Exhibits high compressive strength but lower tensile strength. Its properties can be modified through additives and curing processes to enhance durability and performance.
• Steel: Offers high tensile strength, allowing for lighter and more flexible structural designs. It is susceptible to corrosion, necessitating protective coatings or alloying for enhanced durability.
• Timber: Combines strength with lightweight properties, making it suitable for various structural and aesthetic applications. Its moisture content and susceptibility to pests require proper treatment and maintenance.
