Question on: JSS2 Basic technology - Materials used in Construction

Despite its high compressive strength, concrete can be susceptible to cracking due to shrinkage or temperature variations if not properly reinforced or cured. It requires regular maintenance to address potential issues such as spalling or corrosion of embedded steel reinforcement. Protective coatings and sealants are applied to enhance durability and resist chemical attacks or weathering. Managing these maintenance challenges ensures concrete structures maintain their structural integrity and longevity over time, supporting sustainable construction practices.
