Building structures for the residential, commercial and infrastructure applications have to be inspected and maintained in order to fulfil the functional purpose of the particular structure. Especially in the case of infrastructure, wherein the capital costs are high, timely repair and rehabilitation is vital to keep the wheels of a country’s logistics chain in good shape. To ensure such tasks are implemented properly, the correct choice of materials and repair methodology along with proper assessment strategies are needed. Repair and Rehabilitation has therefore become a specialized field of expertise based on the wide variety of construction chemicals now available. Target Readership The book covers in full the topics prescribed for the Master’s Degree students of Engineering. However, given the fact that a vast number of building structures require urgent attention to implement proper repair strategies, a wide gamut of the topics are covered to facilitate a single knowledge source for consultants and academics alike.
