Pre-stressed concrete methods The methods of application of pre-compression (pre-stress) to concrete can be broadly classified as below: 1. External Prestressing 2. Internal Prestressing 3. Chemical Prestressing 4. Thermo Electric Prestressing  1. External Prestressing:  Image source -Google Images   This method involves generation of compressive force between the structural elements and its abutments using flat jacks. A member can be … Read more

The Basic Principle of pre-stressing The principle of prestressed concrete is to stress the member to a state of compression, such that when superimposed loads are applied the resulting tension developed only tries to reduce the compression already created by pre-stressing. As a result, no tension condition or permissible tension condition in the concrete can be … Read more

Check lists are main things to be known by a Civil engineer specially for site engineers where certain materials or work to be verified.    Here are some of Brickwork checklist 1.    The thickness of joint in brick masonry should not exceed 1 cm. 2.    The face joints should be raked to a depth of 15 … Read more

  Green Concrete -It is a form of concrete which is eco-friendly to the environment that uses less the energy in its production and produces less carbon dioxide when compared to the  normal concrete. The motto of Green Concrete is taken to mean, It should be environment-friendly concrete. As we know cement is the main … Read more

  Segregation in concrete is commonly thought of as separation of some size groups of aggregates from cement mortar in isolated locations with corresponding deficiencies of these materials in other locations. Effect of Segregation in Concrete Segregation in concrete reduces the strength of structural members of houses This may result in the failure of the building during … Read more
