ABSTRACT
Concrete is a commonly used construction material in most parts of the world. However, much of the current available knowledge on concrete technology has been mainly generated in the more developed parts of the world. These regions are mostly in the temperate zone. Hence, much of the standard specifications for concreting practice are based on experience in these cooler regions of the world. When concreting in climatic conditions that are different from the normal range, one should consider these to be extreme climatic conditions.
