How to Evaluate Concrete Piles?

Structure inspection manuals such as the Ontario Structure Inspection Manual (OSIM) mostly emphasizes on the visual inspection and physical condition of bridge structures. The visual inspection methodology in this guideline consists of close up visual assessment of defects in the superstructure and substructure. This methodology is limited to inspection of elements that are at the arms Read more about How to Evaluate Concrete Piles?[…]

Ultrasonic Testing of Anchor Bolts

Ultrasonic Testing of Anchor Bolts

Corrosion inspection of structural anchor bolts can be quite challenging. The reason is that access to these buried elements is often very difficult. The visible part of the bolt is usually in poor quality, and mechanical tests such as pull-out is not an option. Non-destructive ultrasonic testing of anchor bolts provide a very good method Read more about Ultrasonic Testing of Anchor Bolts[…]

Concrete Coring Structure Inspection

Main Challenges of Concrete Coring

Taking core samples from concrete structures is required for comprehensive assessment of durability and structural performance of the structure. The compression test on core samples is known as the most reliable method for assessing the compressive strength and a means of quality control. The procedure for taking core samples and testing them has been standardized Read more about Main Challenges of Concrete Coring[…]
