DESIGN OF CONCRETE STRUCTURES FOR DURABILITY

Design Engineers consider design of concrete structures to mean assessing: i) The size and strength of structural components and concrete strength grade to meet safety and serviceability limits. ii) The amount, size and distribution of reinforcements for strength and control cracks to ...

SELECTION OF CONCRETE REPAIR MATERIALS

Selection of concrete repair materials is based on evaluation of type of damage, types of materials to be used for repair and the local condition. Concrete repairing material must be compatible with the concrete being repaired. Variety of materials is ...

SURFACE PROTECTION METHODS FOR CONCRETE

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 ...

DURABILITY OF REINFORCED CONCRETE TO ENVIRONMENT

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 IN CONCRETE AND PROTECTION

Cavitation damage on concrete surface is most common in case of spillway in dams. This leads to cracks on the concrete surface which further increases the risk of damage to concrete by means of sulfate attack, freeze-thaw, alkali-silica reaction and ...

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

Chemical attacks on concrete structures causes deterioration of structure and its durability is affected. The life of structure reduces and it can lead to failure of structures. The various types of chemical attacks and their effects on concrete structures are ...

PERMEABILITY TEST FOR CONCRETE COVER

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 ...
