Theme: Concrete, without its ability to be durable, has less meaning and utility in the infrastructure sector. Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. It normally refers to the duration or life span of trouble-free performance. Different concretes require different degrees of durability depending on the exposure environment and properties desired. For example, concrete exposed to tidal seawater will have different requirements than indoor concrete.
Concrete will remain durable if:
· The cement paste structure is dense and of low permeability.
· Under extreme condition, it has entrained air to resist freeze-thaw cycle.
· It is made with graded aggregate that are strong and inert.
· The ingredients in the mix contain minimum impurities such as alkalis, Chlorides, sulphates and silt.
A durable material helps the environment by conserving resources and reducing wastes and the environmental impacts of repair and replacement. The production of replacement building materials depletes natural resources and can produce air and water pollution.
Concrete resists weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. Different concretes require different degrees of durability depending on the exposure environment and the properties desired. Concrete ingredients, their proportioning, interactions between them, placing and curing practices, and the service environment determine the ultimate durability and life of the concrete.
The design service life of most buildings is often 30 years, although buildings often last 50 to 100 years or longer. Because of their durability, most concrete and masonry buildings are demolished due to functional obsolescence rather than deterioration. However, a concrete shell or structure can be repurposed if a building use or function changes or when a building interior is renovated. Concrete, as a structural material and as the building exterior skin, has the ability to withstand nature’s normal deteriorating mechanisms as well as natural disasters.
