Durability of Concrete-Effect of Temperature, Chloride & Sulphate

Durability is a major concern for concrete structures exposed to aggressive environments. Many environmental phenomena are known to significantly influence the durability of reinforced Concrete structures. Concrete durability, unlike its structural design properties, is difficult to estimate by indirect means, such as compressive strength or permeation properties. It may be argued that the inability to determine the durability potential of concrete has contributed to the massive current expenditure on repair and maintenance of structure. These conditions are typically found in the externally exposed elements of structure and buildings which may be exposed or sheltered from rain, which accounts for around 2/3 of all structural concrete used. The service life of most reinforced concrete building structures is therefore normally governed by concrete cover and subsequent reinforcement corrosion . In this book experimental investigation work consists of preparation of specimens, casting and testing of specimens, heating exposure technique, Attack of sulphate & chloride and testing of specimens included.
