Evaluation the Compressive Strength in Concrete Structures Using the In-situ Test Methods
Journal Title: Journal of Civil Engineering and Environmental Sciences - Year 2016, Vol 2, Issue 1
Abstract
The new concrete Standards give rules for in situ checking if the hardened concrete in structure achieved the designed compressive strength according the request the class of concrete. Different concrete elements in structure request the different access during the examinations and different analytical analysis. Using the different examination methods will be the main aim on evaluations of concrete strength, always in comparing with requested design class. Core testing and other nondestructive methods assessing strength of surface concrete are generally less reliable than cores, but less damaged will used for final evaluations. More parameters influence the properties of concrete as the type and size of aggregates, cement type and content, placing the concrete, formwork parameters. The different factors analyzing in this paper are combine in the measurements from taking the core samples and results with hammer Schmidt, ultrasonic or other alternative methods. Also the evaluations of compressive strength for different concrete elements in different positions/different layers/ will be the detail expressed in analytical form, because in situ test isn’t possible to implement. Test selection for a particular examinations will be based on a combination of factors such as access, damage, cost, speed and reliability, but the basic features of visual inspection followed by a sequence of tests according to convenience and suitability will generally apply.
