Surface protection of concrete structural members is necessary to protect the structure from damage due to environmental considerations. Corrosion of reinforcement due to permeability of water / moisture, chemical attack on structural members, structures nearby sea-coast etc. are all responsible ...

REPLACEMENT CONCRETE: MATERIALS AND APPLICATIONS
Replacement concrete is a method of repair for defective concrete when the defects or cracks in concrete have large area. In this method of concrete repair, defective concrete is removed from the structural member and area is prepared for repairs ...
Durability of Reinforced Concrete in Different Environmental Conditions
Durability and strength are two most important criteria for the design of reinforced concrete structures. These are the two requirements for the long term performance of concrete structures. Any deficiency in any of the two i.e. durability and strength, could ...
Cavitation Damage to Concrete Structures and its Prevention Methods
Cavitation damage to concrete structure surface is most common in case of spillway in dams. Cavitation damage leads to cracks on the concrete surface.
HOW TO CONSTRUCT DURABLE CONCRETE STRUCTURES
Achieving Durability of Concrete Structures: The durable concrete structures are to be conceptualised, specified, designed, contracted, constructed and maintained. To achieve the design life of the structure at reasonable maintenance cost, the following aspects are required to be taken care ...
Types of Chemical Attacks on Concrete Structures
Introduction When a concrete structure is prone to chemical actions its durability gets affected. The chemicals may cause cracking of concrete, volume change and deterioration of structure. The life of structure reduces and it can lead to failure of structures. ...
Selection of Durable Construction Materials for Concrete Structures
Durable concrete construction requires selection of durable construction materials. Selection and properties of these construction materials are discussed.
Permeability Test for Concrete Cover to Reinforcement
The durability of concrete structures depends on the permeability of reinforcement cover by concrete. It is this thin layer of concrete over reinforcement on which life of a structure depends. The permeability tester for concrete cover is a non-destructive instrument ...
