Ensuring concrete durability and integrity: A cement quality perspective

摘要

Concrete is a composite material composed of cement, aggregates (coarse and fine), admixtures and water. It is the second most consumed material in the world, behind only water. Indeed, twice as much concrete is used in construction projects as all other building materials combined. Its popularity is primarily due to its: ? Flexibility - Concrete can be moulded into virtually any shape; ? Low cost - Especially compared to steel, aluminium and glass; ? Availability - The raw materials for cement are ubiquitous, as are aggregates and water; ? Durability - It is durable and long lasting.
