“…The specimens used in this method are fairly compact requiring small amounts of material as compared with the notched beams employed in three-point bending tests. However, the implementation of this test type requires a more sophisticated fixture than that implied by the three-point bending test so that the number of results available in the literature from WS tests for concrete is scarce (Cifuentes and Karihaloo 2013;Korte et al 2014;Merta and Tschegg 2013;Veselý et al 2011). The fracture behavior is analyzed by wedging out the starter notch.…”

A new approach for measuring the specific fracture energy of concrete denoted modified disk-shaped compact tension (MDCT) test is presented. The procedure is based on previous ideas regarding the use of compact tension specimens for studying the fracture behavior of concrete but implies significant modifications of the specimen morphology in order to avoid premature failures (such as the breakage of concrete around the pulling load holes). The manufacturing and test performance is improved and simplified, enhancing the reliability of the material characterization. MDCT specimens are particularly suitable when fracture properties of already casted concrete structures are required. To evaluate the applicability of the MDCT test to estimate the size-independent specific fracture energy of concrete (G F ), the interaction between the fracture process zone of concrete and the boundary of the MDCTspecimens at the end of the test is properly analyzed. Further, the experimental results of G F obtained by MDCT tests for normal-and high-strength selfcompacting concrete mixes are compared with those obtained using the well-established three-point bending test. The procedure proposed furnishes promising results, and the G F values obtained are reliable enough for the specimen size range studied in this work.

“…However, many of the fracture tests proposed by the previous researchers are not able to cover all mixed mode conditions. One can find several fracture test specimens in the literature such as compact tension (CT) specimen (Wagoner et al 2005, Kim et al 2014, wedge splitting (WS) test (Brühwiler et al, 1990;Issa et al, 2003), three point bend (3PB) specimen (Korte et al, 2014;Seitl et al, 2017;, four point bend (4PB) specimen (Munz et al, 1980;Razavi et al, 2017;Fakhri et al, 2017;Ayatollahi & Aliha 2011) , Brazilian disk (BD) specimen Wei et al, 2015;Akbardoost et al, 2014;Ayatollahi & Aliha, 2009a), semicircular bend (SCB) specimen (Funatsu et al, 2014;Wei et al, 2017ab;Ameri et al, 2012Ameri et al, , 2016Aliha & Fattahi Amirdehi, 2017), center cracked or notched ring specimen (Dehghany et al, 2017;, triangular bend (ECT) specimen , edge notch disc bend (ENDB) specimen (Bahmani et al, 2017;Tutluoglu & Keles, 2011;Aliha et al, 2015Aliha et al, , 2016, Diagonally loaded square plate (DLSP) specimen (Ayatollahi & Aliha, 2009b), and double cantilever beam (DCB) specimen (Ranade et al, 2014;Lopes et al, 2016).

The use of cement concrete as a stronger and more durable material than asphalt concrete in construction of the pavements has been increased during the past decades. This review paper investigates the effect of various input variables for the design of continuously reinforced concrete pavements. A literature review is prepared based on the efforts performed by many researchers to investigate the effect of different factors including temperature change, shrinkage, material properties of the concrete, and concrete slab/ subbase bond properties on the displacements and stresses in the concrete slab. It is found that the important role of concrete slab/ subbase bond strength has not been investigated properly as compared to other input variables.

“…In literature we can found that researchers used various geometries for measurement of concrete fracture properties , e.g. TPB [13,17], WST [4,21], the combination of TPB and WST [29][30], disk shaped compact tension [14,32] and another configurations can be found in handbooks e.g. [22,28].…”

ABSTRACT. The modified disk shaped compact tension test is a configuration derived from standard compact tension test that is used for measuring fracture mechanical properties of primarily metallic materials. The compact tension configuration is commonly used for measurement fracture mechanical properties as e.g. fracture toughness, Young's modulus, work of fracture etc. The modified compact tension tests imply significant modifications of the specimen morphology in order to avoid premature failure. The modified compact tension test is not proper for quasi-brittle materials due to its complicated shape (steel-concrete interface), but it is easily extracted from drill core and we do not need large amount of material for obtaining fracture properties as we need for e.g. three-or four-point bend test. Since it is a new test method, a wide range of tests is needed to be done before it can be applied. In the paper the selected outputs of the experiments performed on normal and high strength concrete will be processed and the values of fracture mechanical parameters will be discussed.
