... for Flexural Toughness of Fiber Reinforced Concrete (Using Centrally Loaded Round Panel) , round panel tests affects the apparent performance and variability in performance of FRC mixtures. The effect of friction was investigated by comparing results obtained using steel support plates of the type described...

...E. S. Bernard; G. G. Xu With the increasing use of fiber-reinforced concrete (FRC) for civil infrastructure projects, challenges have become apparent in quality control (QC) testing for this material. The most common problem is high variability, but a secondary problem is identifying the most...

...E. S. Bernard; G. G. Xu The post-crack performance of fiber-reinforced concrete (FRC) is widely reported to exhibit a high degree of variability. Several reasons exist to explain this problem, most notably the small area of crack surface involved in most beam tests. Of less widely recognized...

... tests. Use of this supporting roller design will lead to a reduction in performance variability between laboratories and improve the confidence users can have in the post-crack properties of FRC. 12 08 2013 27 01 2014 28 02 2014 fiber reinforced concrete friction beam testing...

... variability characteristic of performance parameters obtained using beam tests has burdened the construction industry with unnecessarily expensive FRC designs, because the resulting margin between target performance and design requirements becomes excessively large. In response to this, demand has arisen...

...). The advantage of electrical testing is that it is relatively easy to perform, and the test method is relatively fast (it takes less than a minute). Over the past century, many studies have investigated different approaches for measuring electrical properties. This paper describes the variability associated...
