Post Tensioning (Part-II)

Contd. from Part-I …. The main equipments used in post tensioning operationing are: a) Stressing Equipmemts: These include jack & pump of suitable capacities. Proper calibration certificates for these equipments are quite necessary. For general idea, calibration tolerances for these max be +/- 2%. Calibrations are checked periodically in order to ensure accuracy throughout. Scrutiny … Continue reading

Post Tensioning (Part-I)

Post tensioning is an useful method of reducing size or increasing load bearing capacities of concrete structural elements like bridge decks, girders and suchlike. Unlike pre-stressing, where stresses are applied to steel well before pouring concrete, in case of post-tensioning the same are applied only after concrete attains sufficient strength. Like pre-stressing, Post tensioning too … Continue reading

Structural Steel in project sites (Part-II)

Contd. from Part-I…. Camber or sweep (where necessary), dimensions, layout etc. are checked as per fabrication & erection drawings. Priming & painting of structural steel members are examined as per relevant guidelines. Dry film thickness of paint coats may be checked with ELCO meter. Fabricated structural members are well identified with erection marks in order … Continue reading

Structural Steel in project sites (Part-I)

An integral element of most construction projects is structural steel and steelwork. Few points on inspection of the same in a construction project site, especially for construction personnel with no or very less experience in this field, are briefly discussed here: Upon arrival of structural steel at construction project site, various documents related to those, … Continue reading

Steel Reinforcement

In this article, a brief insight on Reinforcement Steel commonly used in Reinforced Cement Concrete (RCC) work in various construction sites in India is presented. The details would be pretty much same for any project outside India too…….. Continue reading
